DataCite @ UC3The California Digital Library was founded by the University of California in 1997 to take advantage of emerging technologies transforming the way digital information is published and accessed
In collaboration with the UC libraries and other partners, the CDL has assembled one of the world’s largest digital research libraries and changed the ways that faculty, students, and researchers use information
– Collection development, licensing, mass digitization, and cataloging– Digital special collections– Discovery and delivery– Publishing– UC Curation Center (UC3)

UC3’s participation in DataCite is a continuation of our ongoing activities in digital curation
– The set of policies and practices focused on managing and adding value to a body of trusted digital content over time

UC3
The gap between possibility and practice
Journal articles– Most articles held in multiple
academic and national libraries– Libraries ensure long-term
storage and access– Extensive mechanisms for
publication and discovery– Established funded mechanisms
for archival management– Citations form the basis of
impact analysis
Data– Few archives in widely visible
facilities– Difficult data management
after project funding ceases– Little opportunity for
publication, informal discovery– Ad hoc funding sources, if at
all– Not included in impact
analysis

UC3
What we’d like to enable…
Precise identification of datasets at appropriate granularity
Bi-directional linking between traditional publications and the data underlying them
Domain-specific discovery to facilitate innovative reuse of data
Citation “credit” for data producers and publishers
Use metrics for data

Identity is a fundamental curation service
ValueAnnotation of content by consumers
Notification of new content availability
Transformation to create derivatives
ServiceSearch of content and metadata
Index to enable fast search
Curation Ingest of content for curation
PreservationContext
Characterization to extract content properties
Inventory of curated content and metadata
Replication for safety
StateFixity to verify bit-level integrity
Storage for long-term retention
Identity for long-term reference

Easy Identifiers (EZID)Tier 1 Anonymous request for persistent identifier
Tier 2 Tier 1, plus supply of a resolvable URL(c.f. tinyurl)
Tier 3 Tier 2, but authenticated(enabling link checking and personalized services)
Tier 4 Tier 3, plus supply of metadata(enhanced discovery and resolution)
Tier 5 Tier 4, plus supply of the digital asset(for local or brokered hosting)
Tier 6 Tier 5, plus supply of the asset from the web(c.f. Zotero)

Next steps
Work with DataCite partners to establish metadata and citation standards and best practices
Integrate support for DataCite DOIs into EZID
Promote data citation for research, teaching, and learning on UC campuses and by funded project partners
Increase the visibility of UC3 as a DataCite registration agency and the UC3 curation environment for data hosting

Summary
Digital resources lacking identification cannot be curated
Data should be seen (and supported) as a new kind of publication
Scholarly inquiry is facilitated by bi-directional linking between articles and the data on which they are based
DataCite plays a vital role in supporting data as citable publication
UC3 is working with campus and external partners to provide effective data citation services
