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. 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.

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
