I'm certainly no expert. :-) But I think CIDOC-CRM in it's current RDF versions is a bit problematic from a Linked Data POV. The OWL representation [2] has the wrong content type (this is certainly something that can be fixed) and it doesn't have a stable namespace (the term URIs are all relative to the current OWL file). As far as I can see, the way the identifiers are built they cannot be abbreviated in Turtle either. And I'm not happy with the definition of inverse properties. I started manually converting the CRM into OWL (using some OWL 2 constructs like versionIRI and property chains as well) and under a stable purl.org namespace [4]. I'm not done with the properties yet but you can retrieve Turtle and RDF/XML versions and get an idea of what it looks like.
