IPTC Rights Expression Working Group Autumn 2013


Published on

RightsML is the standard rights expression language for the news and media industry. Based on W3C's ODRL, IPTC RightsML lets providers, intermediaries and customers express and evaluate precise, machine processable permissions, restrictions and duties. The goal is to promote the efficient and accurate use of entitled content.

  1. 1. Rights Expression Working Group Stuart Myles * Associated Press * 22nd October 2013
  2. 2. RightsML Publishers need to express rights on the uses of content Often need to enforce rights on behalf of 3rd parties Clients need to know permissions and restrictions Rights are a key criteria for selecting content RightsML is an IPTC standard, based on ODRL Machine processable permissions, restrictions and duties Derived from media industry requirements Can be embedded within content (e.g. G2, ATOM) or stand alone Designed for automatic evaluation

  4. 4. ODRL Encoding (1/3) The ODRL model is designed to be encoded in various formats So far, only the XML encoding has been standardized... © 2013 IPTC ( All rights reserved 4

  7. 7. Driving Adoption • How do we drive adoption of RightsML? • Finish the RightsML 1.0 spec • Provide examples and templates • Solve RightsML in binaries © 2013 IPTC ( All rights reserved 7
  8. 8. Finish the RightsML Spec • Reviewed the RightsML spec from start to finish – Firmed up the descriptions, removed ambiguity – Eliminated some artificial restrictions – RightsML_1.1-EP2-spec-DRAFT_1.pdf • Clarify relationship between ODRL and RightsML – RightsML as a standard – RightsML as an implementation guide – Founded on ODRL, but only need to read RightsML docs • Validating RightsML – ODRL XSD alone is insufficient – We propose to also validate vocabularies and business rules • Probably using Schematron • Still to come... © 2013 IPTC ( All rights reserved 8
  9. 9. Examples and Templates • Documentation and examples – – – Spec is important but implementation is often by copying the examples • Additional restrictions examples have been developed – – – – Geography Time Distribution channel Default “read the editors’ notes” • Templates, designed to be copied and filled in © 2013 IPTC ( All rights reserved 9
  10. 10. Rights in Binaries • Clear theme: rights metadata for photo and video – An id linking to a registry with rights metadata is one approach – Embedding rights metadata in binaries needs to be supported • IPTC experimented with embedding ODRL in XMP – Quickly determined that XMP won’t support arbitrary RDF – We toyed with using double-escaped XML • But concluded that it was an ugly hack a bit inelegant • Express ODRL model (and hence RightsML) in JSON – – – – – – Drafted within W3C ODRL Community Group Try it out and provide feedback Do we like the features borrowed from JSON-LD? Is it a “natural” JSON implementation? Does that matter? Does it work within ninjs? © 2013 IPTC ( All rights reserved 10
  11. 11. RightsML MOTION – Standards Committee MOTION (to the Standards Committee): To approve RightsML version 1.1 as specified by RightsML_1.1-EP2-spec-DRAFT_1.pdf © 2013 IPTC ( All rights reserved 11
  12. 12. Rights Road Map • Try out RightsML and give us feedback – – – – – – Does the spec need further clarifications? Are the use cases, templates and examples helpful? Can you contribute any? What else would help to drive adoption? • Outreach – EU Media Mixer – IPTC Photo Metadata group © 2013 IPTC ( All rights reserved 12
