Dear Robert,

This are good points. I believe such overview information should appear 
on the CRM site, however, someone needs to maintain and update.

WRT technical implementation, per default CRM-SIG provides RDFS. OWL is 
more powerful, but implementers must be careful not to impose 
constraints that come in conflict with more rare exceptions and the need 
to accommodate mutually contradictory alternatives of historical facts.

The idea is further that even Relation databases can implement an 
effective management of CRM instances, if data entry control software 
checks consistent use of entity types and relation types, which 
represent classes and properties. In the past, we have seen such 

Some implementations may implement only small parts of the CRM.

LIDO is regarded to be an XML implementation with a loss-free mapping to 
the CRM in RDFS or OWL, and as such compatible, and promoted by CIDOC. I 
think there are enough systems around of this kind. Of course, they 
cannot be queried by superproperties, possibly some properties and 
classes are parametrized as types, which creates the needs again to 
control consistency between both.

We at FORTH have implemented such systems in XML.

About who uses what, and what is the S/W, I think we need a questionnaire.

About relevant standards, I think we need a questionnaire.

Both I think is part of this issue. Relevance needs to be defined: 
content size? subject coverage? expressive power?. Also, archives and 
libraries keep cultural materials and use their standards in quite 
different ways.

In 2009, I wrote a chapter for the Ontology Handbook
