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.
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.
Within this document, the following namespace prefix bindings are used:

| 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 from party B, the request can still be accepted if party A accepts party B's request conditions. |

| Type | odrl:Operator, owl:NamedIndividual, skos:Concept |
| Definition | Indicates that a given value is of a similar type 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 | This Operator must be used to cover hierarchical relationships between Left and Right Operands, such as rdf:type, rdfs:subClassOf, skos:broader, owl:sameAs, or skos:exactMatch. The Right Operand value MUST use vocabularies that explicitly define subclass relationships, e.g., using rdfs:subClassOf, to be used with this Operator. |

| Type | rdf:Property, owl:ObjectProperty, skos:Concept |
| Definition | Indicates that a Party issued a Policy. |
| Note | Associating a Party with a Policy using the issuedPolicy property does not grant any privileges to the corresponding Party. |
| Example | Method used to indicate that a party, e.g., Alice, has issued a policy, e.g., related to her preferences for data sharing. |

| Note | Can be used for compensation duties where the financial payment is a percentage of the total transaction amount. Value must be between 0 and 100 (decimal inclusive). |
