Second Thoughts About Metadata Standards for Data Presentation Transcript

  • 1. Second thoughts aboutMetadata Standards for Data Joan Starr California Digital Library June, 2012 @joan_starr
  • 2. Our roadmapA brief January recapWhat’s new?Special focus: DOI’s & ARKs By 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 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 anddistribution 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. DOIs and ARKs• 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. 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….
