2. Our roadmapA brief January recapWhats new?Special focus:DOIs & ARKsBy I like http://www.flickr.com/photos/ilike/1174736310/ 3. California Digital Library (CDL) 4. Back in January Requirements for dataset description Common element: long-term identifier, e.g. DOIs A organization for promoting DOIs fordatasets: DataCite A tool for creating & managing: EZID Metadata for describing datasets 5. What is new? Requirements for dataset description Common element: persistent identifier, e.g. DOIs A organization for promoting DOIs fordatasets: DataCite A tool for creating & managing: EZID Metadata for describing datasets 6. EZID: long-term identifiers made easy take control of themanagement anddistribution of your research, share and get credit for it,and build your reputationthrough its collection anddocumentation Primary Functions 1. Create long-term identifiers 2. Manage identifiers over time 3. Manage associated metadata over time 7. http://n2t.net/ezid 8. http://n2t.net/ezid 9. http://n2t.net/ezid 10. http://n2t.net/ezid 11. http://n2t.net/ezid 12. http://n2t.net/ezid 13. http://n2t.net/ezid 14. http://n2t.net/ezid 15. http://n2t.net/ezid 16. DataCite Metadata 3.0 Update ISO 26324:2012: DOI Dublin Core Application Profile A few new additions to controlled lists additions to the description of dataset? Collection time Collection geo-location 17. DOIs and ARKs both can work like regular hyperlinks. both can refer to asubset or portion ofa resource. both become persistentwhen the target URLis maintained. http://content.cdlib.org/ark:/13030/tf0v19n605/, courtesy of UC Davis Special Collections 18. DOIs vs ARKs Case sensitive Special feature supports granularity Informative Less costly 19. DOIs vs ARKs: suffix pass-through string: ark:/99999/Big4 /*prefix suffix location: http://x.y.z/foo/Big4/db/* 20. DOIs vs ARKs: suffix pass-through string: ark:/99999/Big4/table/cell/45-8.txt location: http://x.y.z/foo/Big4/db /table/cell/45-8.txt 21. DOIs vs ARKs Established brand in publishing Indexed by major A&I citation databases Cannot be deleted More costly 22. Plays well with others. 23.
