    • Uses private, voluntary tools to create a public good - more freely* available content
  •  
  • Core Licensing Suite: Creator/Licensor chooses license options NonCommercial No Derivatives ShareAlike Every Creative Commons licenses allows the world to copy and distribute a work provided that the licensee credits the creator/licensor In addition creator/licensor may apply the following conditions:
  •

    • </rdf:RDF>
  • Rights Description Use Cases Discovery Expression Commerce Management(1)
  • Rights Description vs. Rights Management(2) Copy/Use promotion vs. Copy/Use protection Encourage fans vs. Discourage casual pirates Resource management vs. Customer management Web content model vs. 20 th century content model Not mutually exclusive in theory.
  • Why Semantic Web? Small organization, no central registration for every license Decentralization: Let a thousand search engines bloom; web as API Existing RDF tools could take advantage of CC RDF
  • Why RDF-in-HTML comments? (yuck)
    • Considered:
    • Robots.txt-like
    • HTML meta tags
    • LINK to external RDF file
    • RDF-in-HTML comments wins because
    • Metadata colocated with human visible HTML, only single copy & paste for licensors
    • Full power of RDF
    • Metadata colocated with HTML even better (coming soon)
  • CC Search History I
    • Postgresql/tsearch2/python prototype (early 2004)
      • Sloooowwwww, but did what a prototype should do
  • CC Search History II
    • CC-Nutch (late 2004)
      • Nutch aims to be open source search engine comparable to commercial web scale search engines
      • Built on top of Lucene full text index
      • CC plugin only ~500 lines of code (not counting UI, CC-required additions to Nutch core)
      • http://search.creativecommons.org uses Nutch, >1m CC-licensed pages indexed
  •  
  • CC Search History III
    • Yahoo! Search for Creative Commons (early 2005)
      • Search CC-licensed subset of Yahoo!’s index (~15m* pages)
      • *very rough guesstimate
  •  
  •  
  •  
  • CC Search History IV
    • Google CC search (November 2005)
      • Search CC-licensed subset of Google’s index (~45m* pages)
      • *very rough guesstimate
  •  
  •  
  •  
  • CC Search History V (the future) Better metadata formats Image and Video search Derivatives search Content commerce search “ Live” web search “ Management” (desktop, workgroup) Semantic mashups
  • Future CC metadata formats
    • “ Semantic XHTML” AKA “lowercase semantic web” AKA “microformats” (now)
    • <a rel=“license” href=“ http://creativecommons.org/licenses/by/2.5/ ”>
    • “ Hard Core Semantic XHTML” AKA RDF/A AKA XHTML2 metadata (in working group)
    • GRDDL (gleaning resource descriptions from dialects of languages)
  •  
  •  
  •  
  • Image and Video search Better metadata formats Image and Video search Derivatives search Content commerce search “ Live” web search “ Management” (desktop, workgroup) Semantic mashups
  • Searching for Derivative Works
  • Creative Commons (0)
  • Creative Commons (0)
  • Creative Commons (0)
  • Creative Commons (0)
  • Derivatives search RDF/XML snippet: <dc:source rdf:resource=”http://ccmixter.org/media/files/victor/3385”/> Query like Yahoo! link: search or Technorati Cosmos search source:http://ccmixter.org/media/files/victor/3385 “ Who sampled this” as the new “who linked to this”
  • Content commerce search Transaction costs should be low even if rights are reserved Commercial terms and other commerce described by metadata associated with a work Find me work I can use at a price I can pay for usage rights warranty/paper trail (even if rights not reserved) Reintermediate consumer and creator
  • “ Live” web search (feeds) Feeds are explicitly metadata-rich (unlike typical web page) Existing blog search ignores metadata Web search will become more like blog search, vice versa?
  • “ Management” (desktop, workgroup) Desktop search (OS-level) Content creation and media player integration XMP (Flash 8 support?) Semantic Wikis
  • Semantic mashups
  • Issues for Semantic Search on the Public Web Metadata quality Trust Scalability Usability Compatibility Critical mass State of the art IR works very well – high expectations!
  • Issues for Open Licensing and Flash CC is for “content”, offers broad range of choices Free/Open Source licenses have code covered very well Flash can be used for pure content (e.g, movies), pure software “applications” Flash developers and designers come from a different pool than software developers, different mindset. Maybe? Flash development customers need to be educated about CC and open source
  • Non-Issues for Open Licensing and Flash Tons of CC-licensed content (images, music, video) available for use in your next Flash production!
