=head1 NAME

TM::PSI - Topic Maps - PSI (published subject identifiers)

=head1 DESCRIPTION

This package provides predefined subjects, all of which will be preloaded in B<every> map which is
instantiated with the L<TM> package hierarchy. When the subjects are defined also their relationship
are kept here (example: I<isa is an instance of an assertion>).

Every such subject is defined by its

=over

=item B<item identifier>

The internal identifier, which does not really mean much.

=item B<subject identifier>

The subject indicator(s), which is ultimately B<the one> which identifies any of the subjects here.

=back

B<NOTE>: For none of the subjects declared here a subject address exists. All concepts are
TM-related concepts.

The subjects are sorted:

=over

=item B<TMRM>-related

These are the minimal subjects which make a map what it is. Examples are C<isa> and
its related role (type) C<class> and C<instance>, and C<is-subclass-of> and its related
roles.

=item B<TMDM>-related (XTM things)

These are the additional concepts which are mandated by TMDM.

=item B<AsTMa>-related

Here are more concepts which are needed by the AsTMa= language(s), such as C<template> or
C<ontology>.

=item B<TMQL>-related

Here are more concepts which are needed by TMQL.

=back

To learn about these predefined concepts, you can do one of the following

   use TM::PSI;
   warn Dumper ($TM::PSI::core, $TM::PSI::topicmaps_inc, $TM::PSI::astma_inc, $TM::PSI::tmql_inc);

=head2 Taxonometry

Two association types are predefined by the standard(s): C<is-subclass-of> and C<isa>.  Together
with these roles are defined C<subclass>, C<superclass> and C<instance>, C<class>, respectively.

The TM::* suite of packages has these not only built in, but also works under the assumption that
these association types and also the roles B<CANNOT> be subclassed themselves. This means that no
map is allowed to use, say, C<is-specialization-of> as a subclass of C<is-subclass-of>.  The costs
of this constraint is quite small compared to the performance benefits.

=head2 Infrastructure Concepts

To make the whole machinery work, every topic map must contain infrastructure topics such as
C<name>, C<occurrence> etc. They are topics like the topics a user may put into the map. While
this is the right thing to do, in practical situation you often will want to filter out these
I<infrastructure topics>.  You can always get a list of these via
