Creative Commons Metadata Example <ul><li><rdf:RDF xmlns=&quot;; </li></ul><ul><li>xmlns:dc=&quot;; </li></ul><ul><li>xmlns:rdf=&quot;;> </li></ul><ul><li><Work rdf:about=&quot;;> </li></ul><ul><li><dc:title>An Example Article</dc:title> </li></ul><ul><li><dc:date>2003-10-01</dc:date> </li></ul><ul><li><dc:type rdf:resource=&quot;; /> </li></ul><ul><li><license rdf:resource=&quot;; /> </li></ul><ul><li></Work> </li></ul><ul><li><License rdf:about=&quot;;> </li></ul><ul><li><permits rdf:resource=&quot;; /> </li></ul><ul><li><permits rdf:resource=&quot;; /> </li></ul><ul><li><requires rdf:resource=&quot;; /> </li></ul><ul><li><requires rdf:resource=&quot;; /> </li></ul><ul><li><prohibits rdf:resource=&quot;; /> </li></ul><ul><li><permits rdf:resource=&quot;; /> </li></ul><ul><li><requires rdf:resource=&quot;; /> </li></ul><ul><li></License> </li></ul><ul><li></rdf:RDF> </li></ul>
  10. 12. Rights Description Use Cases Discovery Expression Commerce Management(1)
  11. 13. 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.
  12. 14. 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
  13. 15. Why RDF-in-HTML comments? (yuck) <ul><li>Considered: </li></ul><ul><li>Robots.txt-like </li></ul><ul><li>HTML meta tags </li></ul><ul><li>LINK to external RDF file </li></ul><ul><li>RDF-in-HTML comments wins because </li></ul><ul><li>Metadata colocated with human visible HTML, only single copy & paste for licensors </li></ul><ul><li>Full power of RDF </li></ul><ul><li>Metadata colocated with HTML even better (coming soon) </li></ul>
  14. 16. CC Search History I <ul><li>Postgresql/tsearch2/python prototype (early 2004) </li></ul><ul><ul><li>Sloooowwwww, but did what a prototype should do </li></ul></ul>
  15. 17. CC Search History II <ul><li>CC-Nutch (late 2004) </li></ul><ul><ul><li>Nutch aims to be open source search engine comparable to commercial web scale search engines </li></ul></ul><ul><ul><li>Built on top of Lucene full text index </li></ul></ul><ul><ul><li>CC plugin only ~500 lines of code (not counting UI, CC-required additions to Nutch core) </li></ul></ul><ul><ul><li> uses Nutch, >1m CC-licensed pages indexed </li></ul></ul>
  16. 19. CC Search History III <ul><li>Yahoo! Search for Creative Commons (early 2005) </li></ul><ul><ul><li>Search CC-licensed subset of Yahoo!’s index (~15m* pages) </li></ul></ul><ul><ul><li>*very rough guesstimate </li></ul></ul>
  17. 23. CC Search History IV <ul><li>Google CC search (November 2005) </li></ul><ul><ul><li>Search CC-licensed subset of Google’s index (~45m* pages) </li></ul></ul><ul><ul><li>*very rough guesstimate </li></ul></ul>
  18. 27. 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
  19. 28. Future CC metadata formats <ul><li>“ Semantic XHTML” AKA “lowercase semantic web” AKA “microformats” (now) </li></ul><ul><li><a rel=“license” href=“ ”> </li></ul><ul><li>“ Hard Core Semantic XHTML” AKA RDF/A AKA XHTML2 metadata (in working group) </li></ul><ul><li>GRDDL (gleaning resource descriptions from dialects of languages) </li></ul>
  20. 32. Image and Video search Better metadata formats Image and Video search Derivatives search Content commerce search “ Live” web search “ Management” (desktop, workgroup) Semantic mashups
  21. 33. Searching for Derivative Works
  22. 34. Creative Commons (0)
  23. 35. Creative Commons (0)
  24. 36. Creative Commons (0)
  25. 37. Creative Commons (0)
  26. 38. Derivatives search RDF/XML snippet: <dc:source rdf:resource=””/> Query like Yahoo! link: search or Technorati Cosmos search source: “ Who sampled this” as the new “who linked to this”
  27. 39. 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
  28. 40. “ 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?
  29. 41. “ Management” (desktop, workgroup) Desktop search (OS-level) Content creation and media player integration XMP (Flash 8 support?) Semantic Wikis
  30. 42. Semantic mashups
  31. 43. 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!
  32. 44. 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
  33. 45. Non-Issues for Open Licensing and Flash Tons of CC-licensed content (images, music, video) available for use in your next Flash production!
