This is a unique, top-level Class URI for various Semantic Web entailment regimes. Instances include Simple entailment, RDF, RDFS, and D entailments, entailments with Direct and RDF Based Semantics of OWL, and RIF entailment. For the specific entailment regimes, use these URI-s:
- Simple Entailment: (http://www.w3.org/ns/entailment/Simple)
- RDF Entailment: (http://www.w3.org/ns/entailment/RDF)
- RDFS Entailment: (http://www.w3.org/ns/entailment/RDFS)
- D Entailment: (http://www.w3.org/ns/entailment/D)
- OWL Entailment with Direct Semantics: (http://www.w3.org/ns/entailment/OWL-Direct)
- OWL Entailment with RDF Based Semantics: (http://www.w3.org/ns/entailment/OWL-RDF-Based)
- RIF Entailment: (http://www.w3.org/ns/entailment/RIF)

Unique identifiers for the OWL 2 Profiles:
- DL: (http://www.w3.org/ns/owl-profile/DL)
- EL: (http://www.w3.org/ns/owl-profile/EL)
- QL: (http://www.w3.org/ns/owl-profile/QL)
- RL: (http://www.w3.org/ns/owl-profile/RL)
- Full: (http://www.w3.org/ns/owl-profile/Full)
Note that, strictly speaking, OWL DL and OWL Full are not referred to, formally, as “profiles” by the OWL 2 Profiles specification. However, “each profile is defined as a syntactic restriction of the OWL 2 Structural Specification, i.e., as a subset of the structural elements that can be used in a conforming ontology,…” (see the OWL 2 Document Overview). In this sense, and for practical purposes, including a URI for OWL DL and Full is correct. Indeed, OWL DL can be seen as a sytactic restriction of OWL that is particularly well suited for OWL 2 Direct Semantics, whereas OWL Full is a “profile” without any syntactic restriction, and is usually associated with the usage of the OWL 2 RDF-Based Semantics. Note also that there are no separate URIs for the 2004 version of OWL DL; OWL 2 DL, published in 2008 supersede that version. Nor is there a URI for OWL Lite.
