NAME

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

DESCRIPTION

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

Every such subject is defined by its

item identifier

The internal identifier, which does not really mean much.

subject identifier

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

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

The subjects are sorted:

TMRM-related

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

TMDM-related (XTM things)

These are the additional concepts which are mandated by TMDM.

AsTMa-related

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

For the details, please look into the code ;-)

@@@ TODO: describe properly @@@

NOTE: This is still subject to quite dramatic changes. Grounding is such a beast.
