Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.

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". TMQL-related Here are more concepts which are needed by TMQL. 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); Taxonometry Two association types are predefined by the standard(s): "is-subclass-of" and "isa". Together with these roles are defined "subclass", "superclass" and "instance", "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 CANNOT be subclassed themselves. This means that no map is allowed to use, say, "is-specialization-of" as a subclass of "is-subclass-of". The costs of this constraint is quite small compared to the performance benefits. Infrastructure Concepts To make the whole machinery work, every topic map must contain infrastructure topics such as "name", "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 infrastructure topics. You can always get a list of these via @@@ fix docu @@@@@ $tm->mids (keys %{$TM::PSI::topicmaps->{mid2iid}}); SEE ALSO
