ODRL Version 2.1 Ontology
The Open Digital Rights Language (ODRL) provides flexible and interoperable mechanisms to support transparent and innovative use of digital content in publishing, distribution, and consumption of digital media across all sectors and communities. The ODRL Policy model is broad enough to support traditional rights expressions for commercial transaction, open access expressions for publicly distributed content, and privacy expressions for social media.

ODRL Actions vocabulary
Asset
Asset is anything which can be subject to a policy. Asserting that something the target of a policy implies that it is an Asset.
Party
An entity which can participate in policy transactions. Use an instance of the Party class where it's necessary to associate a Scope with the relationship; in other cases, simply reference the party directly.
Policy
A top level entity for describing policies.
Instances of ConflictTerm describe policies for resolving conflicts.
Conflict term
Permissions
Permissions take precedence over prohibitions.
Prohibit
Prohibitions take precedence over permissions.
Instances of UndefinedTerm describe policies for processing unsupported actions.
Undefined values
Ignore
Undefined actions should be ignored.
Invalid
The policy is invalidated.
Support
Undefined actions do not invalidate the policy, but notification for review must occur.
conflict
Relates a conflict-resolution mechansim to a Policy. If no mechanism is specified, the default is invalid.
undefined
Relates the mechanism used for handling undefined actions to a Policy. If no mechanism is specified, the default is invalid.
permission
Relates the description of an individual Permission to a Policy. A permission can be specified either in terms of an Action alone, or an instance of Permission relating an Action and one or more other attributes.
prohibition
Relates the description of an individual Prohibition to a Policy. A prohibition can be specified either in terms of an Action alone, or an instance of Prohibition relating an Action and one or more other attributes.
inheritance allowed
A boolean value indicating whether this policy can be inherited from.
inherits from
Relates a policy to another policy from which terms are inherited.
profile
indicates the identifier of the ODRL Profile for which the policy expression conforms to
Rule
An abstract common ancestor to Permissions, Prohibitions and Duties.
Permission
A Permission is a rule which indicates the actions the assignee is permitted to perform on the associated asset. In other words, what the assigner (supplier) has granted to the assignee (consumer).
Prohibition
A Prohibition is a rule which indicates the Actions that the assignee is prohibited to perform on the related Asset.
Duty
A Duty is a rule which indicates requirements which must be fulfilled in order to receive the permission.
Instances of Action are things one might be permitted to do or prohibited from doing to a work.
Action
Constraint
Parent class of all Constraints.
relation
Relation is an abstract property which creates an explicit link between an Action and an Asset. Sub-properties of relation are used to define the nature of that link.
output
The output property specifies the Asset which is created from the output of the Action.
target
The target property specifies the Asset upon which the Action is performed.
function
Function is an abstract property whose sub-properties define the roles which may be fulfilled by a party in relation to a Rule.
action
The operation relating to the asset for which permission is being granted. A permission must include exactly one action.
constraint
One or more constraints which affect the validity of the Permission; e.g. if the Action play is only permitted for a certain period of time.
duty
A Duty indicates requirements which must be fulfilled in order to receive the permission.
unit
The unit of measurement used for the constraint value.
operator
The Boolean operator applied to a constraint and its operand.
right-operand
The operand applied to an instance of a constraint. Do not use the right-operand property directly within a Constraint. Instead, a Constraint instance must contain exactly one triple which makes use of one of the sub-properties of right-operand.
status
The current value of the constraint. The range of the status property is identical to that of the operand property selected used in the constraint.
Operator
Instances of the Operator class represent boolean operators
Equal to
Indicating that a given value equals the operand of the Constraint.
Greater than
Greater than or equal to
Has part
Is a
Is all of
Is any of
Is none of
Is part of
Less than
Less than or equal to
Not equal to
Use
The Assigner permits/prohibits the Assignee to use the Asset as agreed. More details may be defined in the applicable agreements or under applicable commercial laws. Refined types of actions can be expressed by the narrower actions.
Grant use
The Assigner permits/prohibits the Assignee to grant the use the Asset to third parties. This action enables the Assignee to create policies for the use of the Asset for third parties. nextPolicy is recommended to be agreed with the third party. Use of temporal constraints is recommended.
Compensate
The Assigner requires that the Assignees compensates the Assigner (or other specified compensation Party) by some amount of value, if defined, for use of the Asset.

A new asset is created and may have significant overlaps with the original Asset. (Note that the notion of whether or not the change is significant enough to qualify as a new asset is subjective). To the derived Asset a next policy may be applied.

The Assigner permits/prohibits the Assignees to produce a digital copy of (or otherwise digitize) the Asset from its analogue form.

(Note that the notion of whether or not the change is significant enough to qualify as a new asset is subjective).
