Issue 247: E74 Group - Generalization

Background:

I was wondering if the class "E74 Group" could be generalized as follows: 
"E74 Group" 
     Subclass of "E1 Entity"; 

"P107 has current or former member (is current or former member of)" 
     Domain "E74 Group" 
     Range "E1 Entity". 

With this generalization would be possible to represent groups of any entities (not just E39 Actors). 

For example, in the legislative process, a bill may be part of a group of bills that move together, as they dealt with similar matters. The bill group membership (or the exclusion) is formalized by a document (petition). In the field of cultural heritage, there are examples of groups like this?

Do not be fooled by the name E74 Group! E74 Group is by definition groups of actors. The group of legislation (each an E28 Conceptual Objects)that you are mention is itself, another E28 Conceptual Object). The part decomposition function (using the appropriate Properties depending on the sort of things that have whole-part relationships) generally deals with this kind of thing.

Outcome: 

In 31st joined meeting of the CIDOC CRM SIG, ISO/TC46/SC4/WG9 and the 24th FRBR - CIDOC CRM, the sig decided that no action required. Coincidental aggregations of things can be modelled by enumeration with respect to environment or context, and need not be assigned to an individual persistent identity as a whole.
