W3C has published a set of URI-s to uniquely identify Semantic Web entailment regimes.
These URI-s are needed for the upcoming SPARQL and RIF specifications, but their
usage can be more general and not bound to specific technologies.
The URI-s for the various entailment regimes are:
- Simple Entailment:
- RDF Entailment:
- RDFS Entailment:
- D Entailment:
- OWL Entailment with Direct Semantics:
- OWL Entailment with RDF Based Semantics:
- RIF Entailment:
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.
