1. Metadata Standards for Data Joan Starr California Digital Library June, 2012 @joan_starr Second thoughts about

2. Our roadmap A brief January recap What’s new? Special focus: DOI’s & ARKs By I like http://www.flickr.com/photos/ilike/1174736310/I likehttp://www.flickr.com/photos/ilike/1174736310/

4. Back in January… Requirements for dataset description – Common element: long-term identifier, e.g. DOIs A organization for promoting DOIs for datasets: 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 for datasets: DataCite A tool for creating & managing: EZID Metadata for describing datasets

6. EZID: long-term identifiers made easy take control of the management and distribution of your research, share and get credit for it, and build your reputation through its collection and documentation Primary Functions 1. Create long-term identifiers 2. Manage identifiers over time 3. Manage associated metadata over time

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. http://content.cdlib.org/ark:/13030/tf0v19n605/http://content.cdlib.org/ark:/13030/tf0v19n605/, courtesy of UC Davis Special Collections both can work like regular hyperlinks. both can refer to a subset or portion of a resource. both become persistent when the target URL is maintained. DOIs and ARKs

18. Case sensitive Special feature supports granularity Informative Less costly DOIs vs ARKs

19. location: http://x.y.z/foo/Big4/db /* string: ark:/99999/Big4 /* DOIs vs ARKs: suffix pass-through “prefix” “suffix”

20. string: ark:/99999/Big4 location: http://x.y.z/foo/Big4/db DOIs vs ARKs: suffix pass-through /table/cell/45-8.txt

21. Established brand in publishing Indexed by major A&I citation databases Cannot be deleted More costly DOIs vs ARKs

22. Plays well with others….
