IPTC's RightsML, based on W3C CG's ODRL is the standard for expressing permissions and restrictions for digital content for the news industry. The latest report on progress in implementing RightsML, including a new Python library for creating rights expressions in XML and JSON. https://github.com/iptc/rightsml-dev

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
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

3. ODRL v2

The Core ODRL model supports permissions, restrictions and duties

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...
http://www.w3.org/community/odrl/two/xml/

5. ODRL Encoding (2/3)
There is an official draft for an ODRL ontology

6. ODRL Encoding (3/3)
And an updated draft for ODRL in JSON

7. Driving Adoption
• Working with W3C CG to refine and simplify ODRL 2.0
• Provide more examples and templates
• Create a reference implementation of RightsML software
• Address RightsML in binaries via ODRL in JSON

8. Examples and Templates
• Lots of work on documentation
– http://dev.iptc.org/RightsML
• Simple restrictions examples, designed to be templates
– Geography
– Time
– Distribution channel
– Default “read the editors’ notes”
– Action
– Duty to pay
– http://dev.iptc.org/RightsML-Examples-Simple-Cases
• Re-worked the original examples
– http://dev.iptc.org/RightsML-10-Implementation-Examples
– Using the “simple” examples as building blocks

9. Refining ODRL
• Working with ODRL W3C CG
– Simplify, enhance ODRL
– Improve documentation
• Adding profile attribute
• Adding datatype and unit to constraints
• Slim down the Common Vocabulary
– Remove terms that really belong in their own profiles
– OMA
– CC / CCREL
– ONIX
• IPTC-sponsored legal review of Common Vocabulary

10. Introducing the “licensed” Library
• Create ODRL and RightsML documents
• Supports XML and JSON encodings
– Targets the “to be approved” XML encoding
– Ontology support on the roadmap
• Experimental pure Python library
– Implementations in Javascript and Java planned
• https://github.com/iptc/rightsml-dev/tree/master/licensed
• Helped me discover (and fix) various problems
– In both ODRL specs and RightsML documentation

11. Rights in Binaries
• 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
• Express ODRL and hence RightsML in JSON
– Easy to embed in XMP (unlike RDF or XML)
– Designed to be simpler, more “natural” JSON, akin to NINJS
– Try it out and provide feedback
– Drafted within W3C ODRL Community Group
– http://www.w3.org/community/odrl/work/json/

12. Rights and IPTC Photo Metadata
• Next IPTC Photo Metadata update will add support
– http://dev.iptc.org/RightsML-Requirements-for-Embedding-
Rights-in-Binaries
– A field and a way to convey how to handle it (e.g. MIME type)
• XMP already supports 3+ rights representations
– CC, PLUS, PRISM
– What should providers do? Recipients?
– How should rights in XMP be displayed e.g. in Adobe panels?

13. RightsML and the iptc.org website
• RightsML added to the “main” iptc.org website
• http://www.iptc.org/site/RightsML/
• Continues to be documented in detail on the “dev” site
• http://dev.iptc.org/RightsML

14. How to Drive Adoption?
• What are the hurdles preventing adoption?
• Is there anything else that IPTC can do to help?
