W3C has published a set of URI-s to uniquely identify OWL 2 Profiles.
These URI-s are needed for the upcoming SPARQL specification, but their
usage can be more general and not bound to specific technologies.
The URI-s for the OWL 2 Profiles are:
- OWL 2 DL:
- OWL 2 EL:
- OWL 2 QL:
- OWL 2 RL:
Each of these URI-s can return, depending on content negotiations, XHTML+RDFa, RDF/XML, or Turtle content; the URI-s above with html, rdf, or ttl suffixes, respectively, can also be used to get to those versions directly.
