In 29th CRM-SIG meeting, we discussed about defining an RDF file for CRM CORE in the light of new extensions presented in the following figure 
The CRM-SIG decided
(1) to produce a subset for things, texts, images, persons, Martin Doerr will describe this thing and he will send it for comments
(2) to make explicit some simplification rules
(3) to simplify isA hierarchy without losing semantics
(4) to start to make the profile and to put as issue in the WEB.
In 31st joined meeting of the CIDOC CRM SIG, ISO/TC46/SC4/WG9 and the 24th FRBR - CIDOC CRM and in the frame of this issue the CRM-SIG decided that:
(a) a documentation about CRM family models is needed. This is should be in a central place in the website. Barry and Mark Fichner will work on this.
(b) the SIG should invite for integrated extensions. Steve will write the process whish should be uploaded to the cidoc - crm site. This document should include (a) invitation for extensions (b) what is the procedure (c) what is the current situation.
