Issue 68: How to model isA relations between types

Starting Date:

Status: 
Done
Closing Date:

Background: 

In the light of formalizing better the relation between Types and CRM Entities, and modelling the events of inventing classification terms and systems, the definition of a property in the CRM that expresses isA semantics as the ISO2788 "BTG" relationship seems to be useful. Other relationships used for thesauri, like RT, UF etc, do not have the same relevance for the kind of reasoning the CRM intends to support.

Current Proposal: 

Introduction of a new property with "BTG" semantics: 
E55 Type
has broader term (has narrower term): E55 Type

Outcome: 

Proposal accepted, Monterey 22/2/2002.
