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/

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

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

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….
