    Rights Examples
    “No New York”
    “Not for Yahoo”
    “No Canada mobile”
    “No sales”
    “Any non-commercial use, requires attribution”
    “No Internet/Mobile usage without Football Association Premier League (FAPL) license”
    “No mobile use until 2 hours after the match, website users are obliged to comply with DFL restrictions”
  • 3. IPTC and Rights
    In March 2010, we reviewed IPTC rights support
    NITF, NewsML 1, the G2 Family
    Each offers semi-structured natural language statements
    Conclusion a machine-readable solution is required
    Principally for use within the G2 family of standards
    IPTC would prefer to select an existing language, rather than developing a new REL entirely from scratch

  • 4. Rights Expression Language?
    A machine-readable language to convey rights associated with a piece of content
    Automatically answer the question
    Can we use this content for this particular purpose?
    Rights:
    Permissions and restrictions on the use of a piece of content
    Granted by a rights holder to a user
    Basic Structure:
    {Party A} grants {Party B} the right to {Action C} with {Item D} under {Condition E}

  • 5. IPTC and Rights
    We identified candidate languages
    PRISM, ODRL, PLUS, ACAP, DDM
    Asked for members to supply example natural language rights statements for experimentation
    Examples gathered from TR and AP
    We decided to get involved with ACAP v2
    Started to create a news profile for ODRL v2
    Michael attended a DAM conference
    Questions were raised about patents on RELs

  • 6. Next Steps
    IPTC members can contribute in a number of ways:
    Supply more rights expression examples for evaluation
    Get involved in the ACAP effort
    Help develop the news-specific vocabularies
    Help determine (confirm) the rights expression language
