Graffiti ToDo List
==================
- generalize RDF storage, implement SPARQL
- unit, functional, and performance test suite (in progress)
- separate library for RDF storage (done)
- investigate alternative backends: FramerD, 3store, Redland
-- depends on separate library for RDF storage
-- depends on test suite
- security: Squish literal condition safety (done), limited number of
query clauses (done), dry-run of user-defined query, approvable
resource usage
- query result set representation
- optional patterns and negation (done)
- parametrized queries (done)
-- cache prepared statements
- support blob literals
-- depends on parametrized queries
- vocabulary entailment: RDF, RDFS, OWL
- RDF aggregates storage internalization (Seq, Bag, Alt)
- query introspection
- storage workflow control (triggers)
- transparent (structured) RDF query storage
-- depends on RDF aggregates storage
-- depends on storage workflow control
- subqueries (query premise)
-- depends on transparent query storage
- chain queries
-- depends on native RDF storage
