From: Renato Iannella A permissions and obligations expression system should provide a flexible and interoperable information model that supports transparent and innovative use and resue of digital content across all sectors and communities. The ODRL Information Model supports the business models of open, educational, government, and commercial communities through profiles that align with their specific requirements whilst retaining a common semantic layer for cross-domain interoperability. The ODRL permissions and obligations expression language provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for describing statements about digital content usage. The ODRL Information Model describes the underlying concepts, entities, and relationships that form the foundational basis for the semantics of the ODRL statements . The basis for the deliverables for the Permissions & Obligations Expression Working Group are the reports created by the W3C ODRL Community Group. The ODRL Community Group has developed a family of specifications to support transparent and innovative use of digital assets in the publishing, distribution and consumption of content. The ODRL specifications have been adpoted by a number of leading industry sectors, such as the Mobile sector and the News industry. The outputs of the ODRL Community Group were the ODRL Version 2.1 specifications that were a major update for ODRL and superseded the original ODRL Version 1.1 [[odrl]] (published as a W3C NOTE) The basis for the deliverables for the Permissions & Obligations Expression Working Group are the reports created by the W3C ODRL Community Group.

+The final outputs of the ODRL Community Group were the ODRL Version 2.1 specifications that were a major update for ODRL and superseded the original ODRL Version 1.1 [[odrl]] (published as a W3C NOTE) The following documents are part of the ODRL Community Group report series:
-This specification was derived from the ODRL Community Group's outcomes, and details of the differences are maintained in the Changes from the ODRL Community Group Reports Appendix.

Relationship to the W3C ODRL Community Group Reports
- The mission of the Permissions & Obligations Expression Working Group is to define a semantic Information Model for expressing permissions and obligations statements for digital content based on the ODRL V2.1 Core Model [[odrl21-model]] (as the baseline information model). + The ODRL Information Model defines the underlying semantic model for permissions and obligations statements describing digital content usage. The information model covers the core concepts, entities and relationships that provide the foundational model for content usage statements.
-The ODRL information model is formally specified using UML notation [[!uml]] and utilises the key words “MUST”, “MAY”, “REQUIRED”, and “OPTIONAL” in accordance to [[!RFC2119]]. To make keywords easily distinguishable, this document uses syntax highlighting (formatted coded typeface) to indicate model entities, attributes, and concrete values for the attributes.
