2. UC3
The 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)

3. 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

4. The gap between possibility and practice
Journal articles
Data
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
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

5. 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

10. Identity is a fundamental curation service
Value
Annotation
of content by consumers
Notification
of new content availability
Transformation
to create derivatives
Service
Search
of content and metadata
Index
to enable fast search
Curation
 Ingest
of content for curation
Preservation
Context
Characterization
to extract content properties
 Inventory
of curated content and metadata
Replication
for safety
State
Fixity
to verify bit-level integrity
 Storage
for long-term retention
 Identity
for long-term reference

11. 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)

12. User-facing EZID interfaces
Two primary methods: mint and bind
id = mint (scheme, namespace)
bind (id, url)
bind (id, metadata)
Interface implementations
HTML
mailto:
REST
POST /mint/scheme/namespace HTTP/1.1

13. Repository for cited data

14. Pilot projects UC ETDs Dryad UC Berkeley Water Resources Center

15. 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

16. 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
