I think that might have been my post. I received some private replies  
telling of CRM-based RDF being used at some museums, but unlikely to  
ever be made open to the public.

There's much to like about CRM -- not the least of which is the active  
and helpful community -- but I've concluded that it's overly  
normalized for what I'm trying to do, which is to link data about  
ancient inscriptions to data about places of the classical world.  
Inscriptions are found or observed at places, but in the CRM this  
relationship is always mediated by an event: an inscription is  
discovered during a "finding event", which occurred at some place. We  
are not ready to mint resources for all these events, most of which  
will never be reused, and so we're bypassing and using non-CRM  
properties to relate inscriptions and places.
