Dear Simon,

Thank you verry much for your contribution!

I'd however prefer not to model the Primitive Values as classes,
because this causes another indirection that
hits heavily on query performance. Direct use of RDF literal
for any primitive value is one choice.

I created a new representation of the CIDOC CRM in OWL. The details about this can be found on 
However just quickly summarising it:
The existing OWL implementation did not meet my satsifaction. The OWL file is being served with the wrong content type (can be fixed easily 
though). The URIs used for the terms are relative to the document and therefore depend on the hosting server and change with every version 
which makes them rather unsuitable for a Linked Data context. Also the way the URIs are constructed (with dots) is problematic in various 
RDF syntaxes. Apart from that new OWL 2 constructs like property chains lent themselves rather nicely for implementing the model so I felt I 
might as well create my own ontology. The result of this is available in the Turtle and RDF/XML formats and valid within OWL 2 DL.

I think I cannot post to your mailing list since it's members only but if you want to forward my email there for discussion I'm fine with that!

Looking forward to your feedback,
