ODRL Version 2.2 Ontology
The Open Digital Rights Language (ODRL) is a policy expression language that provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for representing statements about the usage of content and services. The ODRL Vocabulary and Expression describes the terms used in ODRL policies and how to encode them.

Alternative serialisations
The ODRL 2 vocabulary is published both in human- and machine-readable forms. A GET request made to the canonical namespace URI will cause HTTP Content Negotiation to occur, which means that the most appropriate variant will be served according to your request. However, if you explicitly wish to retrieve a particular serialisation, you can also do so using the following URLs:
