Wide review for W3C POE Deliverables

Dear Jean-Pierre,

We write to you in your role as W3C rep at the European Broadcasting Union. Your organisation offered at charter-time to review drafts published by the W3C Permissions and Obligations Expression (POE) Working Group as they are published and send comments.

The W3C Permissions and Obligations Expression (POE) Working Group [1] is delighted to announce the publication of updated Working Drafts of the ODRL Information Model [2] and ODRL Vocabulary & Expression [3]. We would welcome your organisation's feedback.

The ODRL Information Model [2] offers a framework for the underlying concepts, entities, and relationships that form the foundational basis for the semantics of ODRL expressions. The aim of the ODRL Information Model is to support flexible Policy expressions by allowing the author to include as much, or as little, expressive detail about the terms and conditions for Asset usage, the Parties involved, and obligations.

The ODRL Vocabulary & Expression [3] describes the potential terms used in ODRL Policy expressions and how to serialise them. The terms form part of the ODRL Ontology and formalise the semantics. The wide set of terms in the vocabulary provides the support for communities to use ODRL as the primary language to express common use cases.

These deliverables are the outcome of collaborative effort from the Working Group to meet the identified requirements in the POE Use Cases and Requirements NOTE [4]. We believe the ODRL Information Model document and ODRL Vocabulary & Expression are now technically near completion, and would appreciate your final comments before the WG embarks on the W3C Candidate Recommendation process. We are also eager to hear how you are implementing, or plan to implement, the ODRL Vocabulary & Expression to enable us to better understand the serialisaton choices and normative terms.

Please send any comments via the following methods:

1 - Email to <public-poe-comments@w3.org> which is archived [5]
2 - Create an Issue on the POE GitHub Repository [6]

Please send feedback by the 30th April 2017.

We look forward to hearing from you and will respond to all comments.

The W3C Permissions and Obligations Expression Working Group.
