Rights expression for the news industry, using RightsML and ODRL. Updates on the IPTC's Machine Readable Rights Day and the Rights 1.0 spec. Plus documentation and examples of using RightsML and the work so far to embed rights in photo binaries, using JSON.

2. Machine Readable Rights and the
News Industry
• Rights day as part of IPTC’s Amsterdam meeting
• Good mix of people
– technologists, standards bearers, photographers, lawyers ...
• Particular focus on photo metadata
• Embedding rights or use an identifier to link to a registry?
• Various consortia trying to tackle rights
– LCC, PLUS, CEPIC ...
• Summary of meeting, presentations, videos

3. 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
http://dev.iptc.org/RightsML
http://www.w3.org/community/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. ODRL v2
© 2013 IPTC (www.iptc.org) All rights reserved 4
The Core ODRL model supports permissions, restrictions and duties
http://www.w3.org/community/odrl/two/model/

5. ODRL Encoding
© 2013 IPTC (www.iptc.org) All rights reserved 5
The ODRL model is designed to be encoded in various formats
So far, only the XML encoding has been standardized
http://www.w3.org/community/odrl/two/xml/
Experiments in RDF / OWL
http://www.w3.org/community/odrl/wiki/SemanticWeb
And JSON

6. Driving Adoption
• How do we drive adoption of RightsML?
• Finish the RightsML 1.0 spec
• Provide examples and templates
• Solve RightsML in binaries

7. Finish the RightsML 1.0 Spec
• Updated RightsML 1.0 Experimental Phase draft
– RightsML_1.0EP1-revisionDRAFTclean+dirty_2013-06-19.pdf
• Clarify relationship between ODRLv2 and RightsML 1.0
– RightsML as a standard
– RightsML as an implementation guide
– Founded on ODRL, but only need to read RightsML docs
• Validating RightsML 1.0
– ODRL XSD alone is insufficient
– We propose to also validate vocabularies and business rules
• Probably using Schematron http://www.schematron.com/spec.html

8. Examples and Templates
• Documentation and examples
– http://dev.iptc.org/RightsML
– http://dev.iptc.org/RightsML-10-Implementation-Examples
– Spec is important but implementation is often by copying the
examples
• Additional restrictions examples being developed
– Geography
– Time
– Distribution channel
– Default “read the editors’ notes”
• MRR Survey
– http://www.surveymonkey.com/s/iptcmrr2013

9. Rights in Binaries
• Clear theme: rights metadata for photos
– 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 a bit inelegant
• Express ODRL model (and hence RightsML) in JSON
– Work within W3C ODRL Community Group
