Issues Fixed:
Added rdf:HTML
and rdf:langString
from
RDF 1.1.
Update deprecated MySQL engine type syntax. Patch from olberger on github.
Make configure restore CPPFLAGS after virtuoso test. Helps portabilty and Debian hardening.
Fixes to Win32 builds with MSVC2008 from Michael Stahl.
Several alignment and error path fixes from clang and llvm.
Fix rasqal_query_results_next_triple()
call with NULL.
Patch from Michael Stahl.
Issues Fixed:
Requires Raptor 2.0.7 or newer
librdf_model_contains_statement()
now returns > 0
only for invalid statements according to the API contract.
NULL statements are considered invalid.
Fixes Issue #0000489
All the constructors now normalize the nodes (Raptor terms) so that equality is a cheap pointer comparison. Fixes Issue #0000443.
librdf_query_results_get_binding_value()
and
librdf_query_results_get_binding_name()
now fail when
called with negative offsets.
Serializing (using Raptor) now sets the statement graph field to make serializing to N-Quads work.
Loading the same storage multiple times no longer gives a runtime error.
librdf_storage_contains_statement()
now returns >
0 only for invalid statements according to the API contract. Uses
librdf_statement_is_complete()
for testing statement
validity.
hashes storage: Make matching a statement work when using graph names (redland contexts). Fixes Issue #0000515
mysql storage: Defaulted storage configuration host to 'localhost' if it is not given. Opening a store with missing configuration now reports the required keys.
postgres storage: Fixed a bad malloc result test during query
allocation that probably caused
librdf_model_find_statements()
to fail. Fix from
'zoggy' on github - thanks. Made loading triples from a stream to
postgresql actually work via
librdf_model_add_statements()
. Defaulted storage
configuration host to 'localhost' if it is not given. Opening a
store with missing configuration now reports the required keys.
Added librdf_latin1_to_utf8_2()
with size_t args.
Deprecates librdf_latin1_to_utf8().
Added librdf_utf8_to_latin1_2()
with size_t args and
new default arg for replacing out of range characters. Deprecates
librdf_utf8_to_latin1().
Added librdf_world_set_raptor_init_handler()
and
librdf_world_set_rasqal_init_handler()
methods to set
handlers for configuring internal raptor and rasqal after they have
been constructed but before they are initialized; before
raptor_world_open()
or rasqal_world_open()
are run, respectively. Added new typedefs
librdf_raptor_init_handler
and
librdf_rasqal_init_handler
for the handlers.
Added librdf_license_string
and
librdf_home_url_string
static strings to public API
following Raptor and Rasqal naming convention.
No longer gives an error when the same storage module is attempted to be loaded more than once. This is a harmless error and can be generated by installations that include the shared library storage module in a '.so' file and the '.la' file associated with it. Fixes Issue #0000460
Multiple fixes for newer GCC warnings.
Multiple internal fixes for signed int conversions especially around size_t and allocation.
Removed old debugging memory allocation options
--with-dmalloc
for dmalloc and
--with-memory-signing
for internal signing of memory
blocks. Valgrind and static analyzers replace this.
Multiple portability fixes for building out of the source tree. Out of source tree 'make check' and 'make dist' should both work. Thanks to Daniel Richard G. for the patches.
Multiple internal error path cleanup issues and int/size_t issues found via clang static analyzer.
configure now looks for Oracle DB (aka Sleepycat DB aka Berkeley DB) 5.3
autogen.sh now supports the NOCONFIGURE variable like Lib{XML2,XSLT}, aborts the run if an progrma fails and creates the NEWS if it does not exist to aid building from GIT and 'make dist'.
Issues Fixed:
Added new API functions librdf_alloc_memory()
,
librdf_calloc_memory()
and librdf_free_memory()
to allow freeing memory allocated inside librdf shared library, such
as on windows with DLLs. (Lauri Aalto)
Fixes Issue #0000475
Export librdf_new_hash()
to the public API.
BDB Hash now uses the newer 7 args open form in preference to the 6 args form. (Peter O'Gorman / pogma). Fixes Issue #0000468
Reverted librdf_new_statement_from_statement()
to the
pre-raptor_term
deep copy contract for the function.
(Lauri Aalto)
Fixes Issue #0000478
Added librdf_new_statement_from_statement2()
providing a shallow copy of statement which was the
post-raptor_term
semantics of
librdf_new_statement_from_statement()
.
(Lauri Aalto)
Fixes Issue #0000478
Virtuoso storage:
Fixed the parser test to actually test 3 parsers rather than a non-deterministic number. Emits warnings when parser constructor fails since a syntax may not be supported.
Set up the libltdl build dependencies and linking flags properly. Fixes Issue #0000485
Portability changes were made to rdfproc for windows.
Add the REDLAND_CALLBACK_STDCALL
attribute macro in
the serializer log handler for windows.
Multiple librdf and rdfproc(1)
changes to allocate
and free memory using librdf_alloc_memory, librdf_calloc_memory and
librdf_free_memory to ensure memory is allocated correctly across
libraries (DLLs). (Lauri Aalto).
Several code style changes were made.
Rasqal minimum version is now 0.9.25 for the new
rasqal_world_get_query_language_description()
function.
Issues Fixed:
BDB Hash (name 'bdb'): Add checks for Oracle Berkeley DB 5.1, 5.0
and 4.9 and updated configure
messages with the new
name. The 5.x storage has the same API but has a new on-disk format
that will require a use of the db-upgrade(1)
utility in
the utils directory.
Fixed librdf_hash_get_as_boolean()
'false' string
fixed to actually be a False value.
librdf_node_write()
is defined to now always write
N-Triples format.
Blank node ID generation and mapping from parsing is now consistently made across Redland librdf rather than relying on some Raptor defaults. Fixes Issue #0000432
Fixed URI reference leak in
librdf_new_node_from_uri_local_name()
and
librdf_new_node_from_normalised_uri_string()
constructors.
Do not report programmer errors via logging, just runtime errors.
Added
librdf_parser_parse_iostream_as_stream()
and
librdf_parser_parse_iostream_into_model()
from patch by Norman Gray with style fixes by Lauri Aalto. Thanks.
Fixes Issue #0000375
Added librdf_query_language_get_description()
to
return the full description of of the query language. Deprecates
librdf_query_languages_enumerate()
Restored librdf_statement_decode_parts()
to the
public ABI/API which was accidently removed. It has been deprecated
for librdf_statement_decode2()
for some time and now
always fails.
Storage Hashes (name 'hashes'): Fixed a reference leak and shared values issue when cloning a storage. The BDB hash type (current default) was updated for Oracle DB 5.1; see above.
Storage SQLite (name 'sqlite'): Do not add duplicate statements if a context is given. Fixes Issue #0000418. Fixed a librdf_node reference leak when serializing model with context nodes.
Made functions that were already declared in a public header file and documentation into part of the API.
Added but deprecated for Raptor equivalents (they are wrappers for them):
int librdf_unicode_char_to_utf8(librdf_unichar c, unsigned char *output, int length); int librdf_utf8_to_unicode_char(librdf_unichar *output, const unsigned char *input, int length);
Added:
unsigned char* librdf_utf8_to_latin1(const unsigned char *input, int length, int *output_length); unsigned char* librdf_latin1_to_utf8(const unsigned char *input, int length, int *output_length); void librdf_utf8_print(const unsigned char *input, int length, FILE *stream);
The internal Redland librdf AVL Tree implementation was removed
and the 'trees' storage changed to use the AVL Tree implementation in
Raptor (raptor_avltree
) which is newer and has bug fixes
beyond the Redland librdf version.
Redland librdf was ran through the
LLVM clang static code
analyzer and several issues fixed, mostly in unused variables and
values computed that were needed but also included a few use of
uninitialized variables especially in error cases. one problem
fixed was in librdf_world_set_feature()
to actually set
the value for the genid base and genid counter features
(LIBRDF_WORLD_FEATURE_GENID_BASE
and
LIBRDF_WORLD_FEATURE_GENID_COUNTER
respectively)
configure
now tries harder to find the Oracle
Berkeley DB library using Debian multiarch directories if present.
This is yet another heuristic and rather a hack. For a consistent
approach the --with-bdb
, --with-bdb-lib
,
--with-bdb-include
and --with-bdb-dbname
options to configure
should be used.
Use raptor.h
header from Raptor V2.
Removed Raptor V1 support code as librdf no longer supports Raptor V1.
Updated RPM spec file to make Redland librdf package require Raptor V2 (raptor2 package) and Rasqal (rasqal package).
Add sanity checking when initialising Raptor so that there are always parsers and serializers, or something went very wrong and librdf will not work, so return an error.
Removed internal cache module that no code used, didn't seem to entirely work and was never in the public API.
Now configure generates the (untested) win32_rdf_config.h for (untested) WIN32 builds.
Raptor minimum version is now 2.0.0. Raptor V1 support was removed.
Rasqal minimum version is now 0.9.22. Removed use of deprecated Rasqal functions that were conditioned on older rasqal versions.
Issues Fixed:
Mark librdf_node_to_string()
and
librdf_node_to_counted_string()
as deprecated.
librdf_new_parser()
now logs failure to find a parser
for the given name, type and/or uri rather than just returning NULL.
Added librdf_parser_get_description()
deprecating
librdf_parser_enumerate()
.
Fixes Issue #0000325
Added (librdf_query_results_formats_get_description()
deprecating
librdf_query_results_formats_enumerate()
.
Removed toy 'triples' query language. Use 'sparql' instead.
librdf_new_serializer()
now log failure to find a
serializer by the given name, type and/or uri rather than just
returning NULL.
Added librdf_serializer_get_description()
deprecating
librdf_serializer_enumerate()
.
Fixes Issue #0000325
The graph name is now provided to Raptor serializers so that they can write out quads, if supported. At present this works with the 'nquads' serializer.
librdf_new_storage()
,
librdf_new_storage_with_options()
now log failure to
find storage by the given name rather than just returning NULL.
Add new generated version defines to librdf.h:
LIBRDF_VERSION
, LIBRDF_VERSION_STRING
,
LIBRDF_VERSION_MAJOR
, LIBRDF_VERSION_MAJOR
LIBRDF_VERSION_MINOR
and
LIBRDF_VERSION_DECIMAL
(already in earlier versions).
Removed all code in user build of library that calls abort() and replaced with an error log, then failure.
The main changes in this release are:
librdf.h
to be used as the top-level header in addition to redland.h
Issues Fixed:
The main header file for Redland librdf is redland.h
but some applications used librdf.h
direct, which no
longer works in 1.0.11 since some Rasqal symbols were needed.
librdf.h
now includes the raptor and rasqal headers and
redland.h
is a simple wrapper around librdf.h
Redland librdf now links with symbols in libraries used indirectly (only Raptor) to help systems that use GNU ld with a different linking model to previous versions. This is quite technical and hard to understand but see Fedora's change in implicit DSO linking and Understanding the (Proposed) Change to DSO Linking that were introduced in Fedora Core 13 released in February 2010. Redland librdf was packed with patches to fix this, which are now merged into the sources.
Added librdf_stream_get_context2()
returning a
librdf_node*
deprecating
librdf_stream_get_context()
that returns a void pointer.
Fixes
Issue #0000392.
Export librdf_statement_is_complete
to bindings languages.
Fixes
Issue #0000329
Rasqal minimum version has been 0.9.19 for some time but is now
enforced in configure
.
Updated configure
to work with newer autoconf that
enforces AC_LANG_SOURCE
.
Updated examples to build with Raptor V2 also.
The node and statement destructors for the Raptor V2 build now allow NULL pointers like the Raptor V1 versions. Related to Issue #0000391 which had already been fixed for other classes.
The main changes in this release are:
--enable-raptor2
is given to configure
.Issues Fixed:
This release adds support for building with Raptor V2 API as an alternate to the Raptor V1 API. When built with Raptor V2 , librdf uses the Raptor V2 URI, Term and Statement to fully implement the librdf equivalents. Specifically when this is enabled the following are typedefed as equivalent:
librdf_uri
= raptor_uri
librdf_node
= raptor_term
librdf_statement
= raptor_statement
Added --enable-raptor2
to enable librdf to build with
Raptor V2 API. This requires a rasqal built with Raptor V2 API (with
the --enable-raptor2
argument to Rasqal's
configure
). The librdf configure
will
check that Rasqal was built this way and only enable Raptor V2 API
support if it will work.
The minimum Raptor version is now 1.4.19 (or Raptor V2 beta 1.9.0+)
Tests now use the in-memory storage if the BDB (Sleepycat DB) storage is not available.
Updated to prevent an error when used with autoconf 2.68+
Exposed librdf_hash_from_string()
function to public
API for converting from a string to a librdf_hash
object. This is useful for building storage options.
Added librdf_hash_to_string()
function for converting
a librdf_hash
back ito a string, intended to be the
opposite of librdf_string_to_hash()
and takes a filter
arg to help hide arguments such as 'password'.
Added a LIBRDF_FROM_RAPTOR
log facility.
Added librdf_model_write()
deprecating
librdf_model_print()
debug routine.
Added librdf_new_node_from_counted_uri_string()
to make an RDF node from a URI string and length avoiding a strlen()
.
Added librdf_node_get_counted_blank_identifier()
to return ID with length.
Added librdf_new_node_from_counted_blank_identifier()
with counted ID string.
Added librdf_node_new_static_node_iterator()
with
world arg added deprecating
librdf_node_static_iterator_create()
without it.
librdf_node_write()
added to write a redland node to
an iostream, formatted as N-Triples.
Adjusted librdf_node_print()
to use
librdf_node_write()
. If anyone was relying on this
unsupported debug format, this changes the result. Fixes
Issue#0000124
Deprecate librdf_node_to_string()
,
librdf_node_to_counted_string()
for
librdf_node_write()
since these were really only meant
for internal use.
Adjusted librdf_node_to_string()
,
librdf_node_to_counted_string()
to use construct an
iostream to a string and use librdf_node_write()
to
create the strings. Thus the format is now an N-Triples term rather
than the older debug format. These functions are still for debugging
and deprecated for librdf_node_write()
.
Fix rasqal query engine integration to allow querying over the Redland graph names (context URIs) and binding variables to the names. Fixes Issue #000382.
Fix query engine to prevent runtime warning for models with no contexts (graphs) when using GRAPH in a query.
Added librdf_query_languages_enumerate()
function
to list supported query languages.
Made the Virtuoso storage engine (name 'virtuoso') use the internal Rasqal query results formatting API rather than an internal copy of a few query result formatters.
Added
librdf_new_query_results_formatter2()
with
name, mime type and fomrat URI args deprecating
librdf_new_query_results_formatter()
and
librdf_new_query_results_formatter_by_mime_type()
with a mixture.
Altered all query result formatters to all take format name,
mime_type and uri args. Added
librdf_query_results_to_counted_string2()
,
librdf_query_results_to_string2()
,
librdf_query_results_to_file_handle2()
,
librdf_query_results_to_file2()
deprecating the
functions without the 2 suffix.
librdf_serializer_serialize_stream_to_iostream()
and
librdf_serializer_serialize_model_to_iostream()
now
document their ownership transfer of the raptor_iostream
object. Fixes
Issue #0000372
Added librdf_statement_encode2()
,
librdf_statement_encode_parts2()
,
librdf_statement_decode2()
taking a world arg,
deprecating those without the 2 suffx and no world arg.
Added librdf_statement_write()
using librdf_node_write()
to format the statement as
N-Triples.
Adjusted librdf_statement_to_string()
to
use librdf_statement_write() to write statement in N-Triples format
rather than the previous format.
Added librdf_stream_write()
deprecating
librdf_stream_print()
debug routine.
librdf_storage_context_remove_statement()
now checks
that statement is non-NULL and allows NULL context. Now matches
function spec.
Storage Postgresql (name 'postgresql'). Fix the
contains-statement method as called by
librdf_storage_contains_statement()
to work using patch
from Andrew Malton - thanks.
Storage Trees (name 'trees'). Fix the crash bug when comparing nodes one of which has a language and the other doesn't. Issue #0000350.
Storage Virtuoso (name 'virtuoso'). Fix to use the internal Rasqal
query formatting API to allow returning any result format. This is
not using a very efficient mechanism since it results in about 3
copies of the result set: in librasqa;, librdf and virtuoso but it
works and does not duplicate code. Update the storage to support
newer Virtuoso versions such as recent ODBC extensions. Added support
for
SQL_DESC_COL_LITERAL_LANG
SQL_DESC_COL_LITERAL_TYPE
and
SQL_DESC_COL_BOX_FLAGS
from
Virtuoso ODBC Implementation -
Virtuoso ODBC RDF Extensions for SPASQL.
Tested with Virtuoso 5.0.13 open source edition.
Added librdf_new_uri2()
taking a counted URI string
argument, avoiding strlen()
s.
Export librdf_world_set_raptor()
and
librdf_world_get_raptor()
to get/set the raptor world.
These are only used when librdf is built with Raptor V2.
struct librdf_query_factory_s
methods
new_results_formatter
and
new_results_formatter_by_mime_type
are replaced by one
new_results_formatter
method that takes name, mime type
and format URI args. It also gains a
new_results_formatter2
factory method for query results
formatting. The only implementor of this factory is the internal
Rasqal query results formatter.
Exposed several functions (some new) that make sense to higher-level libraries bound to librdf via SWIG:
librdf_hash_from_string()
to build a hash from a string; useful for encoding storage options.librdf_hash_to_string()
to turn a hash into a string; useful for decoding storage options.librdf_model_add_typed_literal_statement()
to add a typed literal statement direct to a graph.librdf_new_node_from_normalised_uri_string()
to create a URI node.librdf_new_node_from_uri_local_name()
to create a URI nodelibrdf_node_get_li_ordinal()
to get the 1 from a rdf:_1 predicate node.librdf_parser_check_name()
for checking parser names.librdf_query_results_is_syntax()
to check if query result is a syntax.librdf_query_results_to_file2()
supplementing the deprecated librdf_query_results_to_file()
librdf_query_results_to_string2()
supplementing the deprecated librdf_query_results_to_string()
librdf_serializer_check_name()
for checking serializer names.librdf_serializer_serialize_stream_to_file()
to go along with it's pair that serializes a model to a file.librdf_serializer_serialize_stream_to_string()
to go along with the pair that serializes a model to string.librdf_world_set_logger()
to set for logging callbacks.rdfproc(1)
utility now send non-result information
messages to stderr, indented to make this more useful for scripting.
It also gains '-q' (--quiet) and '-V' options (--verbose) to control
this output - entirely removing it (quiet) or being more verbose.
That is '-q -v' is equivalent to the default verbosity. Change based
on patch by Norman Gray in issue - thanks! Fixes
Issue #0000334
rdfproc(1)
utility now fails with error when using -n
(make a new storage) to a read only operation such as a query. Fixes
Issue #0000383.
Switched to GIT source control.
Added HACKING.md documenting code style.
Added examples/example8.c
to show how to serializer
query results to strings when queries return either variable bindings
or triples forms.
The main changes in this release are:
Added a Virtuoso storage by Patrick van Kleef
Support Rasqal 0.9.17 API
Fix compiling against sqlite 3.6.17 or newer
Fix modular storage dynamic loading linking problems.
Building requires installed Raptor (1.4.17 or newer) and Rasqal
(0.9.16 or newer) libraries, preferably with pkg-config
to provide the compile/link details.
Issues Fixed:
Default to environment LIBS, CPPFLAGS, LDFLAGS in
configure
to address Gentoo issue
267405
Make redland-src-config work for external raptor and rasqal again. This is for the maintainers only.
Put modular build libltdl includes and libs into INTERNAL macros
librdf_parser_check_name()
added to check if a parser name is
valid:
int librdf_parser_check_name(librdf_world* world, const char *name);
Support Rasqal 0.9.17 API changes including versioned triple
factory and triple sources, RASQAL_LITERAL_UDT
user-defined datatype literals. Use
rasqal_literal_get_rdf_term_type
when available or
fall back to internal version.
librdf_serializer_check_name()
added to check if a
serializer name is valid:
int librdf_serializer_check_name(librdf_world* world, const char *name);
Update storage module link dependencies so that they depend on librdf library to prevent unresolved symbol errors.
More validation of storage module names.
Storages 'file' and 'uri'. These get new storage option
format
with a name value to set the on disk / remote
URI) syntax format. For the both storages it has to be a legal
parser name and for the file storage it has to be a legal serializer
name too. This pretty much limits the values to ntriples, rdfxml and
turtle for the file storage (depending on how raptor is built).
Storage 'postgresql'. Replace deprecated PQescapeString with PQescapeStringConn that takes a PGconn connection handle and when encoding takes into consideration any connection properties such as character encodings in force.
Storage 'sqlite'. Change define SQLITE_API to REDLAND_SQLITE_API to allow redland to compile with sqlite 3.6.17 or newer where the SQLITE_API macro is defined. Thanks to Samuli Suominen for the report and fix.
Storage 'virtuoso'. Added a Virtuoso storage patch from Issue#0000284 by Patrick van Kleef with some parts omitted for passing through SPARQL queries that used rasqal internals.
Export the list helper class to the public API, primarily for use by external storage modules.
rdfproc
utility: for the 'parse' command, get the
warning count from the warning_count_node, not the (just freed)
error_count_node.
Fix totally bogus memset in librdf_cache_set_common()
that zeroed junk on the stack rather than the memory expected.
The main changes in this release are:
Made storages modular by default - separate dynamically loaded
modules discovered from presence in the
PREFIX/lib/redland
directory.
or from the directory defined in the
REDLAND_MODULE_PATH
environment variable directory.
Building requires installed Raptor (1.4.18 or newer) and Rasqal libraries.
Issues Fixed:
librdf_new_node_from_blank_identifier()
read memory after free bug.librdf_storage_postgresql_get_contexts()
fixDeveloper builds from Subversion now require libtool 2.2.0 or
newer to libtoolize
from configure.ac
.
configure
now discovers Berkeley DB 4.7
configure
options --with-raptor=internal
and --with-rasqal=internal
were removed.
Removed openssl digest support - not used much and an extra large dependency. MD5 and SHA1 remain builtin.
Fix to librdf_statement_encode_parts()
for buffer
overrun error that could occur with certain size buffers. Patch from
Lou Sakey - thanks.
Made the redland storage module API
librdf_storage_factory
public. What was called the
storage context is now less confusingly called the storage
instance.
Moved iterator and stream get_method
flags to public
API as new enums since they are used by the storage modules API.
Moved librdf_log()
and librdf_log_simple()
into public API to allow external storage modules to log messages.
More checks for failure during storage instance allocation.
postgresql storage: Fixes for "Numerous leaks, potential NULL pointer use, and dropped postgresql errors and buffer overruns in the postgresql storage module" based on patches in Issue #0000286.
sqlite storage: Fixes to prevent deadlocks with BEGIN
IMMEDIATE
instead of the default BEGIN DEFERRED
.
No longer writes to the sqlite database when just querying. Several
other fixes.
trees storage: Several fixes.
Multiple Win32 build fixes based on patches from Lou Sakey - thanks.
Added librdf_parser_guess_name2()
to SWIG API.
Added LRU cache for internal use.
Several autogen.sh updates for libltdl.
Use libtool's libltdl
to dynamially load storage
modules. Will link in a copy from sources if not present in the
system from libtool.
Internal raptor and rasqal sources removed - now use
pkg-config(1)
to find external libraries to compile and
link to.
Fixes for AVL Tree: update parent pointers when deleting - patch from Aymeric Barthe - thanks.
Added internal support for upcoming Raptor V2 API. Not yet enabled.
Added librdf_world_get_raptor()
and
librdf_world_set_raptor()
methods.
Added librdf_parser_guess_name2()
with librdf_world parameter
and deprecated librdf_parser_guess_name()
without it.
Wrapped deprecated functions with REDLAND_DISABLE_DEPRECATED
blocks.
The main changes in this release are:
Updated to use Rasqal 0.9.16 (Rasqal 0.9.16 release notes) from 0.9.15. NOTE: Rasqal's ABI and API changed so Redland 1.0.8 requires 0.9.16 or newer.
Updated to use Raptor 1.4.18 (Raptor 1.4.18 release notes) from 1.4.16.
Added a new in-memory indexed storage 'trees' using AVL Trees
Issues Fixed:
NOTE: The next release of redland will NOT include raptor and rasqal in the tarball, they will be separate download dependencies.
NOTE: In the next release of redland, the
redland-config
utility that provides the compile and link args will be deprecated, generate a warning when run and will turn into a wrapper forpkg-config redland ...
It will be removed in a future release.
configure
was updated to ensure that redland 1.0.8+
will work with rasqal 0.9.16 to 0.9.99 only.
librdf_parser_set_feature()
now handles setting
feature values as strings or integers, depending on the required
type (although Raptor will handle this too).
Added librdf_parser_parse_file_handle_as_stream()
and
librdf_parser_parse_file_handle_into_model()
helper
methods.
librdf_serializer_set_feature()
now handles setting
feature values as strings or integers, depending on the required
type (although Raptor will handle this too).
Added a new in-memory storage named "trees" by Dave Robillard that uses AVLTrees internally for faster indexed triple store/querying. This is an alpha quality storage since it is brand new and it may be changed in future.
LIBRDF_URI_RDF_MS
, LIBRDF_URI_RDF_SCHEMA
public API macros changed definition to pass in a world parameter.
Added librdf_get_concept_ms_namespace()
and
librdf_get_concept_schema_namespace()
to make the
concept macros above work.
Added an rss2atom example program.
Update configure to use autoconf 2.5.x AC_CHECK_TYPES
for testing byte, u32 and u64.
Fixes for resilence under low memory and allocation failures.
Applied some updates from running the Linux 'sparse' utility.
Allow get_context method calls in stream/iterator map functions. Originally reported on redland-dev 6 May 2008 by John Fieber.
The storage method
librdf_storage_find_statements_in_context()
now uses the
storage factory method find_statements_in_context if it exists,
instead of always using the find_statements factory method and
filtering.
The main changes in this release are:
Updated to use Rasqal 0.9.15 (Rasqal 0.9.15 release notes) from 0.9.14. NOTE: Rasqal's API will change in 0.9.16 so Redland 1.0.7 requires 0.9.15 exactly - no newer, no older.
Updated to use Raptor 1.4.16 (Raptor 1.4.16 release notes) from 1.4.15.
Added modular storage backends. When
--enable-modular
is given to configure, all the storage
major backends are compiled as dynamically loadable modules. The
memory, file and uri storages are always available. This is not
enabled by default as it is a new feature.
Issues Fixed:
configure
was updated to ensure that redland 1.0.7
will work with rasqal 0.9.15 only due to the future API change coming
in the next rasqal version.
Make lots of writable static data truly constant especially from
writable static data from rdf_concepts. This causes a
SOURCE COMPATIBILITY BREAK: the
rdf_concepts.h
public API node and uri
macros now require a librdf_world*
parameter.
Added librdf_parser_set_uri_filter()
and
librdf_parser_get_uri_filter()
to set and get parser
URI filters, passed on into raptor.
Several SQLite storage improvements and fixes were made:
Added librdf_uri_compare()
to compare uri objects
rather than rely on stringifying them and comparing the strings.
Many low memory and error path, resource leak fixes for parsers, streams, module factory construction and module initialising.
librdf_serializer_set_namespace()
now allows NULL uri
and prefix to be given.
librdf_storage_mysql_transaction_commit()
now
terminates if there is no work to commit.
autogen.sh version comparsion was fixed so that 1.10 is seen as newer than 1.9.
The main changes in this release are:
Updated to use Rasqal 0.9.14 (Rasqal 0.9.14 release notes) from 0.9.13.
Updated to use Raptor 1.4.15 (Raptor 1.4.15 release notes) from 1.4.13.
Plus a new transactions API for changes to the graph, implemented and tested for MySQL.
Added a new query results formatter class to turn a query results object into a syntax.
Added a model transaction API:
librdf_model_transaction_start()
to begin the transactionlibrdf_model_transaction_start_with_handle()
to begin it
using an existing connection pointer (such as a MySQL connection)librdf_model_transaction_commit()
to commit the changeslibrdf_model_transaction_rollback()
to abort them (automatic
if not commited before a close)librdf_model_transaction_get_handle()
to
get a handle associated with a connection.Fixes Issue #0000038
Implemented the Transaction API for MySQL (tested) and PostgreSQL (not tested).
Invert test in librdf_model_add_submodel()
.
Fixes Issue#0000175
Added librdf_parser_guess_name()
to guess a parser
name from content, similar to how a parser is constructed from
content.
Added functions to return the namespaces declared during a parse:
librdf_parser_get_namespaces_seen_count()
to return the
number seen, librdf_parser_get_namespaces_seen_prefix()
to
get the prefix string and
librdf_parser_get_namespaces_seen_uri()
to get the
librdf_uri*
.
Added a new Query Results Formatter class building
librdf_query_results_formatter*
objects
to turn a query results into a syntax such as SPARQL query results
formats, JSON. New functions:
librdf_new_query_results_formatter()
and
librdf_new_query_results_formatter_by_mime_type()
.
librdf_free_query_results_formatter()
librdf_query_results_formatter_write()
to write the query results to an iostream.librdf_query_results_formats_check()
and librdf_query_results_formats_enumerate()
Added librdf_query_results_is_syntax()
to
check if a query result is a syntax, and not any of the other
possibilities - bindings, boolean or graph.
Default to serializer named "rdfxml" if no name is given to ensure another rdfxml serializer such as XMP is not returned.
The MySQL storage implements the transaction API. It batches up all the pending insertions and aggregates them so that any set of triple writes during the transaction sequence are all done at one point, with 4 INSERTs only.
Added a supporting
functions librdf_hash_interpret_template()
to
interpolate variables into strings using a librdf_hash of
key/values.
The MySQL storage now takes an optional storage option 'layout' that can choose between the v1 and v2 SQL schemas (only the table type has changed). The SQL fragments are described in Turtle files that are installed and read on startup.
Packagers note: two new files are installed into PREFIX/lib/redland for the MySQL schemas. Without them installed, the MySQL storage will not work.
Removed the configure
script option
--enable-parsers
since Raptor is always required and
always used inside Redland whether or not any parsers were configured.
Use pkg-config
Libs.private in
redland.pc
for internal dynamically linked libraries.
redland-config
gains an --private-libs option to hold
private libraries moved from --libs which now only contains -L and a
-lrdf.
Added a building utility touch-mtime.pl
to handle touch -r
which does not work on SunOS.
Fixes
Issue #0000159
Added librdf_world_open()
for every public API
constructor or function that mentions librdf_world* and could have
failed to run librdf_world_open()
after
librdf_new_world()
. This makes
librdf_world_open()
entirely optional.
Fixes
Issue #0000173
rdfproc
gains an --transactions / -T option for
enabling transactions on the command line and an --results / -r
option to set the query results formatter name.
Do not throw away the rasqal node type information now, it is needed
later on in FILTER
comparisons.
Fixes
Issue #0000153
Fix reference count problem in storages that caused connections to fail to free in MySQL. Fixes #0000150
Fix reference count / memory leak in file storage.
The main changes in this release are:
Updated to use Rasqal 0.9.13 (Rasqal 0.9.13 release notes) from 0.9.12.
Updated to use Raptor 1.4.13 (Raptor 1.4.13 release notes) from 1.4.9.
Plus several API additions and many bug fixes.
configure
now removes un-necessary tests for C++ or
F77++ compilers that libtool stupidly insists on. Add lots of
gcc -W
flags when they are supported and in maintainer
mode.
Made configure --with-threads
work.
Fixes
Issue #0000125

Updated to use Raptor 1.4.8 (Raptor 1.4.8 release notes)
A large source re-arrangement was performed for raptor and rasqal inside redland. All C sources and headers that build the libraries were moved to the src dir, general documentation in the doc dir and utilities in the utils dir for each sub-library.
Version Control change: Redland will be switching to use Subversion for version control after the 1.0.3 release. Please check the Redland Subversion site for the latest status or the online Redland installation notes for the redland specific subversion installation information.
A new PostgreSQL storage backend was added contributed by Shi Wenzhong based on the MySQL storage backend. Fixes issue #0000046
The autogen.sh script for building from CVS was revamped to be more modular.
configure
now takes an --enable-gtk-doc
option to enable building of the documentation using the
gtk-doc
utility. It is by default enabled only if the
utility is available.
The GNOME gtk-doc
program is now used to
automatically extract documentation from source comments into
reference documentation. This is then merged with templates and
additional documentation to provide a reference manual for redland
as XML document which is turned into HTML along with GNOME devhelp
support.
Some win32 build fixes were made.
librdf_world_get_genid()
was changed to include the
process ID in the generated blank ID.

librdf_world_set_uris_hash()
Added examples/example7.c to read from an RDF/XML file, add a triple and write it back.
The changes in this release are:
ORDER BY
and some SPARQL syntax updates.
The main changes in this release are to update to use Rasqal 0.9.9 (Rasqal 0.9.9 release notes) to provide improved SPARQL query support for the revised syntax Raptor 1.4.6 (Raptor 1.4.6 release notes) to provide a new GRDDL parser as well as updated RSS enclosures support with the RSS tag soup parser and RSS 1.0 serializer.
The digest and hash classes now expose public API constructors, destructors and methods via their header files.
Added --with-memory-signing
to check when memory is
allocated / freed across Redland libraries.
Added Win32 portability fixes and build configuration (John Barstow)
The following changes were made to the bindings API as
exported by the SWIG interface file Redland.i
:
The digest class was added:
constructor librdf_new_digest
,
destructor librdf_free_digest
and methods librdf_digest_init
,
librdf_digest_update
,
librdf_digest_update_string
,
librdf_digest_final
and

.
Added a librdf_new_empty_iterator
helper to make an
always-empty iterator.
Added LIBRDF_FROM_MEMORY
facility.
All methods returning an librdf_iterator
or
librdf_stream
now return an empty iterator/stream rather
than NULL when returning an empty result sequence. Errors are still
returned as NULL.
Removed unused LIBRDF_NODE_TYPE_RESERVED1
(#3) from
librdf_node_type
enum.
Update to use Rasqal 0.9.9 API. Redland 1.0.1 will not build with older Rasqal releases.
The query API gains methods librdf_query_get_limit
,
librdf_query_set_limit
,
librdf_query_get_offset
and
librdf_query_set_offset
for setting and getting query
result limit (max results) and offsets (result to start from).
Fixed some across-library memory allocation/frees between redland and rasqal that caused problems on win32. Requires rasqal 0.9.9 or newer.
Added a librdf_new_empty_strea
helper to make an
always-empty strea.
The MySQL store now uses a portable method across endiannesses to create a 64bit key. This fixes Issue #0000023 (Morten Frederiksen)
NOTE: This matches the algorithm used for little-endian systems but big-endian stores will need to serialize the store before upgrading and reload afterwards.
The MySQL store now uses connection pooling to prevent making a new connection to the database for each request. Fixes Issue #0000027 (Morten Frederiksen)
The SQLite store now does not skip items with the factory methods for serializing, finding statements, serializing contexts and getting context statements. Fixes Issue #0000006
All store methods that return an librdf_iterator
or
librdf_stream
now return an empty iterator/stream rather
than NULL when returning an empty result sequence. Errors are still
returned as NULL.
Added REDLAND_INLINE
macro, which can be overridden if
inline is not wanted.
This is Redland 1.0.0.
The main changes in this release are to update to use Rasqal 0.9.6 to provide improved SPARQL query support for optionals, CONSTRUCT, ASK, builtins, Raptor 1.4.4 to provide better serializing to RDF/XML and RSS 1.0 and better RSS tag soup parsing and a new experimental SQLite storage supporting SQLite V2 and V3 libraries.
The storages compiled into redland can be individually selected
with the --enable-storages=
LIST configure
option.
The default for --with-dmalloc
is now no. Reason:
valgrind.
Removed configure altering the search PATH - which was a bad idea as it makes the configure environment different from the user's.
Added /opt/local
to the BerkeleyDB / SleepycatDB
search path to help darwinports.
To help Redland built as an OSX Framework with ObjectiveC, Redland
public headers can be put in a different directory structure if
LIBRDF_OBJC_FRAMEWORK
is defined in the build
environment. In this case the headers are found in a subdirectory
Redland
. This only applies to the public Redland header
files that #include
other public header files -
redland.h
including librdf.h
,
librdf.h
including several rdf_*.h
files
and Rasqal's rasqal.h
including
raptor.h
. (Patch from René Puls)
rdfproc
RDF processor utility program changesAdded a size
command calling
librdf_model_size
.
Added librdf_model_contains_context
to find a context
node in a model.
The librdf_model_sync
now returns a success or failure
int.
Updated to Raptor 1.4.4 providing an updated RSS tag soup parser with fixes for RSS 0.9, RSS.1.1 and Atom.
The constructor now finds the correct parser when given NULL arguments for mime type or type URI.
Update to Rasqal 0.9.5
providing improved SPARQL support: new optionals handling,
CONSTRUCT
to make RDF graphs, formatting of query
results in the SPARQL XML format along with many other improvements
and fixes.
Added base_uri argument to librdf_new_query
Added
librdf_query_results_to_counted_string
,
librdf_query_results_to_string
,
librdf_query_results_to_file_handle
and
librdf_query_results_to_file
to get the results of a query written to a syntax using
Rasqal's rasqal_query_results_write and Raptor's XML writer API.
Added boolean returning methods:
librdf_query_results_is_bindings
,
librdf_query_results_is_boolean
,
librdf_query_results_is_graph
for testing result formats
and librdf_query_results_get_boolean
to get a boolean
result back.
Updated to Raptor 1.4.4 providing a new XML writer API, an improved RDF/XML serializer allowing user namespace declarations and relative URIs, a new RSS 1.0 serializer.
The serializers now respect any user-declared namespaces done with
librdf_serializer_set_namespace
by passing it on to the
Raptor serializer with raptor_serialize_set_namespace
.
At present only the Raptor RDF/XML serializer uses these
user-declared namespace hints.
The constructor now finds the correct serializer when given NULL arguments for mime type or type URI.
The storages compiled into redland can be individually selected
with the --enable-storages=
LIST configure option.
SQLite Storage. A new experimental storage supporting SQLite V2 and V3 libraries.
MySQL storage. Return failure early if the connection failed rather than try to continue opening the storage.
MySQL storage. Only use mysql_real_escape_string
if
a connection was made. Do not try to free resources such as the
mysql DB connection owned by iterators after an error, let
librdf_free_iterator
tidy up. (Patch from Morten
Frederiksen)
Handle resolving against a base URI with an omitted path.
Removed librdf_concept_labels
- never used or
exported.
This is Redland 1.0 Release Candidate 2.
Redland's License was changed from LGPL 2.1/MPL 1.1 to LGPL 2.1/Apache 2
The main changes in this release are to update to use Rasqal 0.9.5 to provide initial SPARQL query support and to use Raptor 1.4.2 to provide serializing to RDF/XML and N-Triples.
rdfproc
RDF processor utility program changesUpdated to allow an optional base URI for the
serialize
command and to handle the three forms
of query results - bindings, graph or boolean.
Added librdf_model_to_string
and
librdf_model_to_counted_string
to serialize a model to a
string using the Serializer class functionality. Exported
librdf_model_to_string
to the language bindings.
Now requires Rasqal 0.9.5 which provides initial support for the SPARQL Query Language for RDF, W3C Working Draft, 12 October 2004 from the W3C RDF Data Access Working Group (DAWG).
Pass on errors and warnings via the existing Redland logging mechanism. Previously they all went to stderr, the default.
Switched to use Raptor 1.4 series serializing classes so now provides RDF/XML and N-Triples serializing and will gain any fugure serializing formats as Raptor adds them.
Using the Raptor support, the serializers can now serialize to
strings in addition to the existing serializing to FILE* and files.
This is performed by the new methods:
librdf_serializer_serialize_model_to_file_handle
(deprecating librdf_serializer_serialize_model
),
librdf_serializer_serialize_model_to_string
and librdf_serializer_serialize_model_to_counted_string
.
Exported librdf_serializer_serialize_model_to_string
to the language bindings.
librdf_storage_context_add_statement
and
librdf_storage_context_add_statements
-
With a NULL context, call the non-context method as documented.
Fixed bogus '+' in get_contexts
method in the mysql
storage.
librdf_world_get_feature
now returns a
librdf_node*
, librdf_world_set_feature
takes a librdf_node*
value. Export these to
the language bindings.
Revert the statement class usage counting - it broke things.
This is Redland 1.0 Release Candidate 1.
The main changes in this release are the addition of the Query and Query Results classes, and the removal of the language bindings into the new Redland Bindings package.
The interface between the Redland library and Redland Bindings
when done via swig is by the
swig interface file Redland.i
which is now installed in
/usr/share/redland/Redland.i
.
Several patches for building Redland natively on Win32
were provided by Jose Kahan. These included
adding an win32_rdf_config.h
hard-coded config
for Win32, using that in the all the C source files and adding an
REDLAND_STATIC
define to help statically linking Win32
builds of Redland.
Redland 0.9.17 requires Raptor 1.3.2 and Rasqal 0.9.1. Installed
versions are used if available by default, otherwise the copies in
the source tree will be used. The
--with-raptor=
and
--with-rasqal=
configure options with
values internal
or system
can be
used to select when both are available.
Removed all the language binding-specific configuration code
including options such as --with-perl
that are now used
by Redland Bindings.
Updated the RPM spec file to remove building of the redland-perl and redland-python RPMs which are now made in the redland-bindings package.
Added -lrdf
to the pkgconfig redland.pc file (Curtis Hovey)
Redland requires automake 1.7 and autoconf 2.54 to build from CVS.
The Query
(librdf_query
) and
Query Results
(librdf_query_results
) classes are new in Redland 0.9.17.
They provide RDF query support with
RDQL
using Rasqal
0.9.1, which is now included in the Redland distribution.
The Query class has the following functions and methods:
librdf_new_query
(constructor)librdf_new_query_from_query
(constructor)librdf_new_query_from_factory
(factory constructor)librdf_free_query
(destructor)librdf_query_execute
The Query Results class has the following methods:
librdf_query_results_as_stream
librdf_query_results_get_count
librdf_query_results_next
librdf_query_results_finished
librdf_query_results_get_bindings
librdf_query_results_get_binding_value
librdf_query_results_get_binding_name
librdf_query_results_get_binding_value_by_name
librdf_query_results_get_bindings_count
librdf_free_query_results
(destructor)A new example example5.c was created to demonstrate using the query classes.
An enhanced logging API was added to provide enhanced information
from log messages, error and warnings such as from parsing. The new
world method librdf_world_set_logger
allows setting of
the log handler callback which gives a
librdf_log_message
. Parts of this the structure can be
read by using the following new accessors methods:
librdf_log_message_code
librdf_log_message_level
librdf_log_message_facility
librdf_log_message_message
librdf_log_message_locator
The locator returns an raptor_locator
that gives the
line, column, byte offset, URI and/or filename of the message.
Raptor 1.3.2+ provides accessor methods for that structure
that are described in
libraptor.3.
Check that duplicate statements are not added to models with the
librdf_model_add_statement
and
librdf_model_add_statements
methods. The methods for
adding statements with a context do not check.
Added librdf_model_query_execute
method to execute a
librdf_query
against a model, returning an
librdf_query_results
Added librdf_model_load
method that uses Raptor
parser guessing to load content from a URI into a model.
The contexts methods now give a run time warning if called when the model does not support contexts or the are not enabled. The methods affected are:

.
Fix assert bug in librdf_node_get_blank_identifier
that caused it to always fail.
A bug was fixed in librdf_node_get_li_ordinal
to not always fail, returning -1
Deprecated methods librdf_parser_set_error
and
librdf_parser_set_warning
which never worked. The
new logging API works correctly with this code.
Where possible, check that duplicate statements are not added to
stores with the librdf_storage_add_statement
and
librdf_storage_add_statements
methods. The methods for
adding statements with a context do not check.
The "mysql" storage was updated by Morten Frederiksen to revise the schema and to add two new features, controlled by new boolean storage options:
bulk
: whether model/storage method add_statements
should be optimized, until a model/storage sync operationmerge
: whether to maintain a table with merged modelsContext methods will now give a run time warning if called and contexts are not supported or enabled. The methods affected are:
librdf_storage_context_add_statement
librdf_storage_context_remove_statement
librdf_storage_context_serialise
librdf_storage_get_contexts
Fixed a memory leak
inside librdf_storage_find_statements_in_context
.
A bug was fixed in method
librdf_storage_node_stream_to_node_create
to allow the
second node parameter to be NULL, so that methods
librdf_storage_get_arcs_out
and
librdf_storage_get_arcs_in
that can use it to work.
A small but important fix to make the installed C headers work
correctly again. The rdf_uri.h file had #include
rdf_digest.h
which is an internal header and not installed.
This required removing two functions from the public API that
returned librdf_digest*
, but neither of them could be
used since rdf_digest.h was not shipped.
Patched librdf.h and raptor.h to #include stdio.h
so
that the empty program #include <redland.h>
main() {}
now works (ditto for raptor).
This version of Redland updates to use Raptor 1.2.0 (raptor news) along with the new syntax Turtle Terse RDF Triple Language.
Three new storage modules were added:
The details of these modules are explained in much greater detail in the storage modules overview including the features that they support.
The runtime is now compiled with assertions to check for illegal
use of NULL pointers in arguments, these will give warning messages
(which can be disabled with --disable-assert-messages
).
The storage and model classes now track when open iterator and
streams are operating on them and will not release resources until
all the open iterators and streams are finished.
There are many changes are to properly use and return UTF-8
strings as unsigned char*
for URIs (looking forward to
Internationalized Resource Identifiers, IRIs emerging) and for RDF
literal strings, plus other fixes to work better with C++ correcting
the use of const
. Redland and Raptor now both compile
cleanly with g++ 3.2, 3.3 and all warnings enabled.
rdfproc
RDF processor utility program changesrdfproc was extensively updated and it can now more easily work with any type of Redland store and has better support for working with contexts. The detailed changes are as follows:
password
from standard input, to prevent
exposing it as a parameter.write=yes
storage option)._:
abc as blank node arguments.Redland 0.9.15 requires Raptor 1.2.0 either installed otherwise the copy in the source tree will be installed.
--with-mysql=
CONFIG added to point to the
mysql_config program for the MySQL backing store
--with-threestore
added to enable the
AKT Triplestore
--disable-assert
added to disable
compiling run-time assertions.
--disable-assert-messages
added to disable
compiling run-time assertion messages.
A redland-python RPM package is now provided and the default RPM packaging now provides the MySQL store, in addition to the in-memory and BDB previously packaged. The new file and uri stores are also available. The full list of store modules is described further in the storage modules overview.

Updated to match API changes above. Fixes for OSX 10.3
Updated to match API changes above. Fixes for perl 5.8.1 and
later which changed how MakeMaker
installed. Let perl
install the files rather than try to force it based on the prefix
argument to configure. Make Parser method parse_string_into_model
call the correct Redland function. Added OSX Java directories
to JDK search path.
Updated to match API changes above. Redland is now started up and shutdown once in the PHP module code and does not need to called directly.
Updated to match API changes above. Fix Node literal_values
to work with datatype URIs. Export the NS class. Added
a FileStorage class for the storage type file
.
Removed use of the python Distutils which was often
getting the linking wrong.
Updated to match API changes above.
Updated to match API changes above.
Redland now ships with both portable MD5 as well as (new in 0.9.15) SHA1 digest implementations used if neither is available via an optimised library.
This version of Redland is an update mostly to synchronise with the Raptor version 1.0.0 (RDF/XML and N-Triples parser) - see Raptor NEWS for the changes since 0.9.12.
New in this version is the rdfproc utility which allows command line creation of redland stores, parsing of syntaxes and manipulation of the model.
Added --with-raptor
to either choose the system
or internal raptor library. If omittted, redland will guess
and choose either the system one, if new enough or the internal
one (always present).
Added a librdf_hash_put_strings
helper method to put a pair of
string values into a hash. Useful for making model or storage
options.
Resource (URI) / literal / blank nodes are now interned on
construction so there is only one object for each distinct
librdf_node
object. This reduces memory and makes
copying cheaper at the cost of an increase in construction cost.
Copying nodes is very common, since not only is it done for nodes but
any time a statement is used or returned. This interning was already
done for the URI class but the change required
librdf_node
to be made immutable, which was done in
0.9.13.
Added librdf_storage_context_as_stream
deprecating
librdf_storage_context_serialise
to be consistent with the
*as_stream method name changes to model.
Added librdf_new_storage_with_options
taking an
librdf_hash*
of options rather than the string of librdf_new_storage
.
Added new optional storage factory methods context_add_statements and context_remove_statements. If omitted, the storage class implements them with context_add_statement and context_remove_statement.
Optimised the stream and iterator internals to do less factory method calls when looking for new items or the end of stream/iterator. This should make them slightly faster.
Renamed Redland statics to be librdf_*
rather than
redland_*
. Added a one-line
librdf_short_copyright_string.
Fixed the broken use of UNIVERSAL::isa
This version of Redland is a major update to 0.9.12 changing the
node class. librdf_node
objects are now immutable once created,
higher-level language APIs no longer have deal with sharing or
copying internals, some additional API support for parsing content
from strings.
This includes the stable and complete version 0.9.12 of the Raptor parser which supports all of the revised RDF/XML syntax.
Initial work was added on an ECMA CLI interface using the C# ("C sharp") language.
Blank nodes generated by parsing the syntaxes are now generated more unique (not guaranteed) based on the Redland startup time and a serial number.
The Perl, Python and Java APIs now always return new nodes and statements removing the need to consider sharing at this level. This means that the following operation is legal in Perl, Python and Java:
# perl $n=RDF::Redland::Node->from_uri("http://example.org/foo"); $s=new RDF::Redland::Statement($n, $n, $n); $model->add($s); # python n=RDF.Uri("http://example.org/foo") s=RDF.Statement(n, n, n) # n is used as a resource RDF.Node here model.add_statement(s)
Several improvements were made to the building and configuring including a better attempt to find matching Sleepycat/Berkeley DB header and library files (and support BDB up to 4.1), searching for installed Java JDKs and Tcl headers. Each of the language interfaces can be individually enabled to be build, tested and installed with the main C library.
The librdf_node
class was modifed to make objects
immutable once constructed, they cannot be modified. The following
set methods were consequently removed.
librdf_node_set_blank_identifier
librdf_node_set_li_ordinal
librdf_node_set_literal_value
librdf_node_set_type
librdf_node_set_typed_literal_value
librdf_node_set_uri
The following utility methods were added (covering
all the librdf_node_get_type
values):
librdf_node_is_blank
- return non-0 if the node is a blank nodelibrdf_node_is_literal
- return non-0 if the node is a literallibrdf_node_is_resource
- return non-0 if the node is a URI(These are reflected into the same methods on the Perl, Python and Java node classes)
LIBRDF_NODE_TYPE_LI
as returned by librdf_node_get_type
was deleted, it was never used.
To support datatyped literals, the following method was added:
Added ibrdf_model_sync
to sync the model to the backing store.
Added librdf_model_as_stream
and
librdf_model_context_as_stream
to replace
librdf_model_context_serialise
and
librdf_model_context_serialize
respectively. This was
done both to reduce the confusion with the
librdf_serializer
class and the mixture of US/UK
spelling of that word. The old functions will remain for now.
Added librdf_parser_parse_string_as_stream
and
librdf_parser_parse_string_into_model
to allow parsing
content from strings.
Added librdf_statement_is_complete
to test if a
statement has all the subject, predicate and object fields assigned.
Partial statements cannot be added to a model but can be used in
matching statement queries with
librdf_model_find_statements
.
Added librdf_storage_sync
to sync the backing store.
(This is slightly internal to Redland, you should not be calling this
directly)
Updated to make the object constructors less verbose and to allow
Redland URI objects and native perl URIs to be used in place of
Redland Nodes where convienent (such as in making Statements). All
existing code should work but can be shortened.
A new --with-perl
configure argument to enable the perl
interface.
A major update to use Python 2.2+ idioms and features by Edd
Dumbill with help from Matt Biddulph for unit tests. A new
--with-python
configure argument to enable the python
interface. Edd wrote the following change log.
General changes
Additions for the new API calls as outlined above (such
as model/storage sync, parsing from strings etc.). New configure
argument --with-jdk
to pick the JDK in order to
find the JNI headers. See the java API
page for details.
Updates in configuring and building these interfaces and new
--with-php
, --with-ruby
and --with-tcl
configure arguments. See the corresponding API pages and
installation documentation for details. Tcl now tries to guess the
includes directories.
librdf_model
class into model interface
(librdf_model
) and implementation class
(librdf_model_storage
).--with-threads
that locks key shared
classes to allow separate threads to work in the same memory
space. The current locked classes are URI and World.This version of Redland is a major update to 0.9.11 incorporating a much more improved, complete and stable version 0.9.7 of the Raptor parser and a significant new feature, contexts. The high-level language APIs received some updates and the start of two new languages APIs were added: Ruby and PHP.
Several incompatible API changes were made in this release that effect the C interface and all the higher level language APIs. These were made to support contexts and to fix some inconsistencies in the interface about object ownership.
The persistent storage format was changed to support RDF typed literals and this requires an upgrade of any existing Berkeley/Sleepycat DB stores created by Redland 0.9.11 or earlier. A utility redland-db-upgrade is provided that will create an updated store from an existing one.
A Perl script utils/update-api-0912.pl can help automate the API changes as far as possible or warn about those that cannot be automatically updated.
This feature allows a Node to be given whenever a statement is
added to a model which can can be retrieved from any model query that
returns answers as an Iterator of Nodes or a Stream of Statements.
Both of these classes gained a new method get_context
that returns the original Node that was given when the statement
corresponding to the answer was added to the model.
The context node can also be used to add and remove sets of statements to/from a model, and each statement with a given context node can be listed as a stream of statements.
Adding this feature required substantial internal changes to these two classes and the internal storage apis and implementations along with moderate code changes at the application level, which are described below.
This feature can be used for the following (not an exhaustive list):
The Iterator
get_next
method was split into get_object
always returning a pointer to a shared object and the
next
method to advance the iterator.
The get_object
method is generally called
current
in the higher level language APIs.
(Iterator and Stream now have consistent method names; they may be merged in future.)
The get_object
method now always returns a pointer to
a shared object. If this object is needed outside the scope of an
iteration, it must be copied, which for Nodes is the copy constructor
librdf_new_node_from_node
.
C example for Redland 0.9.11 and earlier:
while(!librdf_iterator_end(iterator)) { node=(librdf_node*)librdf_iterator_get_next(iterator); /* do something with the node */ }
Redland 0.9.12:
while(!librdf_iterator_end(iterator)) { node=(librdf_node*)librdf_iterator_get_object(iterator); /* do something with the node */ librdf_iterator_next(iterator); }
A new method get_context
was added returning a Node
for the context of the original Statement that generated the Iterator
Node.
C Iterator context example:
while(!librdf_iterator_end(iterator)) { node=(librdf_node*)librdf_iterator_get_object(iterator); context_node=(librdf_node*)librdf_iterator_get_context(iterator); /* do something with the node and its context */ librdf_iterator_next(iterator); }
The Model
add_statement
method no longer takes ownership of the
passed in statement object. The caller now retains ownership and can
reuse the statement several times and has responsibility for freeing it
if need be (when it isn't shared).
C example for Redland 0.9.11 and earlier:
librdf_model_add_statement(model, statement);
Redland 0.9.12:
librdf_model_add_statement(model, statement); librdf_free_statement(statement);
C streaming statement example for Redland 0.9.11 and earlier:
while(!librdf_stream_end(stream)) { librdf_statement *statement=librdf_stream_next(stream); /* This statement is new, so could be added directly */ librdf_model_add_statement(model, statement); }
Redland 0.9.12:
while(!librdf_stream_end(stream)) { librdf_statement *statement=librdf_stream_get_object(stream); /* This statement is now shared so can still be just added */ librdf_model_add_statement(model, statement); }
librdf_model_add_string_literal_statement
lost the
xml_space argument.
A new method was added to add a Statement with an RDF datatyped literals object:
int librdf_model_add_typed_literal_statement(librdf_model* model, librdf_node* subject, librdf_node* predicate, char* string, char *xml_language, librdf_uri *datatype_uri);
This should be used in preference to
librdf_model_add_string_literal_statement
which remains
in the API as a wrapper around the above.
New methods were added to add, remove and list Statements to contexts.
/* Add a single statement to the model with context */ int librdf_model_context_add_statement(librdf_model* model, librdf_node* context, librdf_statement* statement); /* Add all statements on the stream to the model with context */ int librdf_model_context_add_statements(librdf_model* model, librdf_node* context, librdf_stream* stream); /* Remove a single statement from the model with the given context */ int librdf_model_context_remove_statement(librdf_model* model, librdf_node* context, librdf_statement* statement); /* Remove all statements from the model with given context */ int librdf_model_context_remove_statements(librdf_model* model, librdf_node* context); /* List all statements in the model with the given context */ librdf_stream* librdf_model_context_serialize(librdf_model* model, librdf_node* context);
The Node class gained a new constructor:
librdf_node* librdf_new_node_from_typed_literal( librdf_world *world, const char *string, const char *xml_language, librdf_uri* datatype_uri);
that should be used in preference to
librdf_new_node_from_literal
which remains in the API as
a wrapper around the above.
librdf_node_new_nodefrom_literal
lost the
xml_space argument.
The Parser class has an updated
Raptor parser
version 0.9.7 - parsers named raptor
for RDF/XML
(MIME Type application/rdf+xml
)
and ntriples
for N-Triples. See the
Raptor NEWS
for the detailed changes since 0.9.5 in the last release of Redland.
The Java SiRPAC parsers sirpac-stanford
,
sirpac-w3c
and the W3C LibWWW parser libwww
have been removed. Raptor replaces them.
The Serializer class gained a new method:
int librdf_serializer_serialize_model_to_file( librdf_serializer* serializer, const char *name, librdf_uri* base_uri, librdf_model* model);
This writes the serialized model to a filename
(rather than a file handle as done by
librdf_serializer_serialize_model
)
which is easier to use from higher level language APIs until a
cross-language I/O abstraction is available.
The class gained an RDF/XML serializer that can be called
either by the name rdfxml
or the
MIME Type application/rdf+xml
. The
examples in each language have been updated to demonstrate
using this.
The built in storage factories (memory
,
hashes
) now both support contexts. These are enabled by
adding the storage option contexts='yes'
to the options
string. The hashes storage additionally supports indexing predicates
as an extra hash which can be enabled with index-predicates='yes'
.
This makes triple queries of the form
(subject unknown, predicate known, object unknown) fast.
C Example of creating a 0.9.12 storage that does contexts using on-disk Berkeley/Sleepycat DB:
storage=librdf_new_storage(world, "hashes", name, "hash-type='bdb',write='yes',new='yes',contexts='yes'");
The Stream
next
method was split into get_object
always returning a pointer to a shared Statement and the
next
method to advance the iterator.
The get_object
method is generally called
current
in the higher level language APIs.
(Iterator and Stream now have consistent method names; they may be merged in future.)
C example for Redland 0.9.11 and earlier:
while(!librdf_stream_end(stream)) { statement=(librdf_statement*)librdf_stream_next(stream); /* do something with the statement */ }
Redland 0.9.12:
while(!librdf_stream_end(stream)) { statement=(librdf_statement*)librdf_stream_get_object(stream); /* do something with the statement */ librdf_stream_next(stream); }
A new method get_context
was added returning a Node
for the context of the Statement.
C Stream context example:
while(!librdf_stream_end(stream)) { statement=(librdf_statement*)librdf_stream_get_object(stream); context_node=(librdf_node*)librdf_stream_get_context(iterator); /* do something with the statement and its context node */ librdf_stream_next(stream); }
The Perl interface
moved to the RDF::Redland
package (the RDF
namespace was deprecated in 0.9.11).
The interface was updated to receive Redland error and warning
messages callbacks. These can be set using the
RDF::Redland::set_error_handler
and RDF::Redland::set_warning_handler
subroutines
taking a subroutine argument. They are called with a single
scalar argument which is the Redland message.
The interface was updated to match the Interator and Stream changes described above.
Perl iterator example for Redland 0.9.11 and earlier:
while(!$iterator->end) { my $node=$iterator->next; # do something with the node }
Redland 0.9.12:
while(!$iterator->end) { my $node=$iterator->current; # do something with the node $iterator->next; }
Perl stream example for Redland 0.9.11 and earlier:
while(!$stream->end) { my $statement=$stream->next; # do something with the statement }
Redland 0.9.12:
while(!$stream->end) { my $statement=$stream->current; # do something with the statement $stream->next; }
Perl example of using the Serializer class:
# Use any rdf/xml parser that is available my $serializer=new RDF::Redland::Serializer("rdfxml"); $serializer->serialize_model_to_file("output.rdf", $uri, $model);
The Python interface gained pydoc comments, along with an HTML derived version.
The interface was updated to receive Redland error and warning messages callbacks as python exceptions. These can be caught using the standard python try {} catch {} blocks.
The interface was updated to match the Interator and Stream changes described above.
Python iterator example for Redland 0.9.11 and earlier:
while not iterator.end(): node=iterator.next() # do something with the node
Redland 0.9.12:
while not iterator.end(): node=iterator.current() # do something with the node iterator.next()
Python stream example for Redland 0.9.11 and earlier:
while not stream.end(): statement=stream.next() # do something with the statement
Redland 0.9.12:
while not stream.end(): statement=stream.current() # do something with the statement stream.next()
Python example of using the Serializer class:
# Use any rdf/xml parser that is available serializer=RDF.Serializer() serializer.serialize_model_to_file("output.rdf", model)
The Java classes were updated to have
a finished()
method that the user can call to cleanup
objects replacing the rather useless Java finalize()
method that gives no guarantees to when it is called.
The Java API is still experimental and may change further.
