Linking research & learning technologies through standards
Community engagement1st question: Why use identifiers?
Basic idea:– separate identification– from other aspects of a
thing• e.g.
Helps manage resources over time
– discovery– delivery
…– move– replicate/copy– version– re-format– derivative works– license

Community engagement2nd question: What should I identify?
A five step information & service modeling program
1. What things exist?• Concrete & abstract
2. What are the relationships between things?• Aggregations, transformations, versions, copies, … • Granularity: identify whole or parts?
3. Which things matter?• Identify those things
4. Define services that act on identifiers• Retrieve(ID) = ?
5. Decide when to identify things

Information modeling exampleSteps 1 & 2. what things exist?
Example model:
Functional Requirements for Bibliographic Records
(FRBR)

Information modeling exampleStep 3. what matters enough to identify?
At each level– identifiers– distinguishing
metadata
June 2008 2008 Handle Workshop
Linking research & learning technologies through standards
Information modeling exampleStep 4. define services
Resolve(ID): distinguishing metadata about the resource
Retrieve(ID):a copy of the resource
FRBR-Retrieve(ID):a copy of the HTML format of the most recent version
Appropriate-Copy(ID, Context): a copy appropriate for the context

Another service exampleReferent integrity
• Provide assurance that the identified thing has not changed• e-Research & e-Portfolio use cases
Freeze_association(ID):change the referent’s state to “frozen” (can no longer change)
Verify_association(ID):indicate if the referent has changed
Verified_retrieve(ID):a copy of the resource if it has not changed
• Implemented via checksum stored in Handle record • NB: access to the checksum is restricted

Community engagementSummary of high level advice
1. Model your information!
2. Include identifiers in the modeling
3. De-couple identifier management from information management
4. Build information management services that leverage identifiers

Register:
• naming authorities that come under a national licence
• information for managing and policing national policy
• authority information for archival purposes

The road ahead?
Status June 2008:– Strengthened ability to use identifiers
– Proposed sustainability options
Opportunities June 2008– Australian National Data Service (ANDS)
• E-research• An identifier service underpins many of the proposed services
– Digital Education Revolution• Schools (K-12)• Identifier service being scoped to support: federated repositories,
appropriate copy, licensing, derivative works …
– National Library of Australia interested in hosting a national cross-sector identifier service
