7. Does it allow commercial use?

8. Are derivative works allowed?

9. How do we attribute the work?

12. A place creators to collect work references

13. A platform for digital copyright registry exploration

14. Free Software: AGPL 3, available from code.creativecommons.org

17. Allow applications to query registrations

18. Allow creators to mark works as “registered”

20. Support registries other than CC Network

23. This is an exploratory project; we probably don't have all the answers

24. We should just get out of the way

26. Integrate registration information on CC Deeds

27. Allow others to play

28. Prior Art

30. We encode this in the generated HTML

31. Our deeds look at the Referrer to find this

33. And we consume it

35. We could parse the RDFa client side if not for that restriction

37. Retrieves it and extracts RDFa

39. Registering Works

41. We also record the license URI

42. Publish a single page per Registration

43. A Registration may include multiple Works

44. RDFa is used to encode the registration information

46. We could insert the RDFa with Javascript but that severely increases demand on consumers

53. We want to make sure it doesn't break

54. We can use a stock RDFa parser to test this

56. Querying Registrations

58. Others may implement differently so useful to perform “discovery”

59. We can publish assertions about the service

60. Ideally the “protocol” assertion contains enough information for developers to build a client implementation

64. On failure, HTTP 404

65. “Validating” Registrations

67. How can other agents trust claims we publish?

68. Need an additional piece of “confirmation”

72. Reciprocal Ownership Metadata “ Identity” Work

73. The Deeds Are An Application

74. Network + License Badges

78. sioc:memberOf

79. Metadata Instead of Coupling

80. Metadata Instead of Coupling

85. Time outs

87. Vocab mix-n-match is fine: use established vocabularies whenever possible (DC, etc).

88. If you're a market leader (or hope to be), commit to publishing a minimum set of information.

89. Think about your URIs – you're making a commitment to maintain them.

90. Ongoing Work & Improvements

93. Need to supply the details of a specific Offer

96. Would like to write assertions as SPARQL queries instead of JSON array traversal

98. jSPARQL YAHOO.cc.mta.MTA_INFO = { select: [ &quot;offer&quot;, &quot;material&quot;, &quot;disease&quot;, &quot;offer_permits&quot;], where: [ { pattern: [ &quot;?offer&quot;, &quot;http://www.w3.org/1999/02/22-rdf-syntax-ns#type&quot;, &quot;http://mta.sciencecommons.org/ns#Offer&quot; ] }, { pattern: [ &quot;?offer&quot;, &quot;http://mta.sciencecommons.org/ns#agreement&quot;, document.URL ] }, ... }

99. JSPARQL Querying YAHOO.cc.mta.MTA_INFO = { select: [ &quot;offer&quot;, &quot;material&quot;, &quot;disease&quot;, &quot;offer_permits&quot;], where: [ { pattern: [ &quot;?offer&quot;, &quot;http://www.w3.org/1999/02/22-rdf-syntax-ns#type&quot;, &quot;http://mta.sciencecommons.org/ns#Offer&quot; ] }, { pattern: [ &quot;?offer&quot;, &quot;http://mta.sciencecommons.org/ns#agreement&quot;, document.URL ] }, ... } var query = new RDFQuery(store); var results = query.query2(YAHOO.cc.mta.MTA_INFO); // iterate over our result set query.walk2(results, { action : function (obj) { // obj has attributes for each selected value document.write(obj.offer); }});

101. What if I want to know about all the records?

103. Easily deployed with WSGI

104. [real soon now]
