ODRL Community Vocabulary

This document contains a community-supplied set of general terms that are useful across difference use cases where the usage of ODRL policies is desirable.

Introduction

The ODRL Community Vocabulary provides a set of RDF classes, predicates, and named entities that conform with the ODRL Information Model [[odrl-model]] and extends the ODRL Core Vocabulary [[odrl-vocab]]. These terms have been used by the community across multiple ODRL Profiles and, as such, have been deemed useful to be collected and maintained by the ODRL CG.

New additions to this vocabulary can be submitted through GitHub issues and will be discussed by the ODRL CG community to be integrated.

Policy

Preference

IRI	https://example.org/odrl-comm#Preference
Label	Preference Policy
Type	rdfs:Class, owl:Class, skos:Concept
Subclass of	odrl:Policy
Disjoint with	odrl:Agreement, odrl:Offer, odrl:Privacy, odrl:Request, odrl:Ticket, odrl:Assertion
Definition	A Preference Policy is a policy that contains information about the assigner's preferences over an Asset which MAY not be satisfied.
Note	A Preference Policy MUST contain at least one Permission or Prohibition rule, an Action, a target Asset and a Party with Assigner function (in the same Permission or Prohibition). The Preference Policy MAY contain a Party with Assignee, but MUST not grant any privileges to those Parties.
Example	If a preference policy set by a party A does not match a request policy from party B, the request can still be accepted if party A accepts party B's request conditions.

IRI	https://example.org/odrl-comm#isNotA
Label	Is not a

Label	Semantic equivalence
Type	odrl:Operator, owl:NamedIndividual, skos:Concept
Definition	Indicates that a given value is equal to, an instance or a subclass of the Right Operand of the Constraint.

Definition	Indicates that a given value is a subclass of the Right Operand of the Constraint.
Example	The purpose constraint of a rule can be a subclass of research and development such as academic research, non-commercial research or commercial research.
Note	Right operand value MUST use vocabularies that explicitly define subclass relationships, e.g., using rdfs:subClassOf.
