Another ontology/vocabulary which is centred around events is the CIDOC
CRM (Conceptual Reference Model). [1] It is "a formal ontology intended
to facilitate the integration, mediation and interchange of
heterogeneous cultural heritage information", and comes out of the
museums community. There is an OWL representation [2] which has been
developed by a group at Erlangen-Nuremburg University. It certainly
doesn't lack definitions ;-)
I would be interested to hear what Linked Data folks make of it as a
potential framework for expressing more general event-related
assertions, i.e. going beyond its stated scope. I would also value a
more expert opinion than my own as to whether the current expression of
the CRM (either the OWL or RDF [3] version) is "fit for purpose" as a
Linked Data ontology.
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.
