Unique URI-s for OWL 2 Profiles

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: http://www.w3.org/ns/owl-profile/DL
• OWL 2 EL: http://www.w3.org/ns/owl-profile/EL
• OWL 2 QL: http://www.w3.org/ns/owl-profile/QL
• OWL 2 RL: http://www.w3.org/ns/owl-profile/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.
