Towards a common infrastructure?

• e-Learning Framework– Technical Framework to support E-Learning

http://www.cetis.ac.uk/members/frameworks/index.html

• JISC Information Environment– Technical architecture based on open standards (Web Services,

OAI-PMH, Z39.50, RSS…..) http://www.ukoln.ac.uk/distributed-systems/jisc-ie/arch/

• Virtual Research Environment– Framework options e.g. CHEF, Chandler, SAKAI, ??

• Common Information Environment– A cross-sectoral vision– Demonstrators– Ariadne article http://www.ariadne.ac.uk/issue39/miller/

Why advocate a standards culture?

• Open standards• Maximise access

– Platforms and delivery channels– Widest range of users

• Avoid proprietary lock-in– Vendor independent

• Integrate with other initiatives– eLearning e.g. Curriculum Online

• Economic benefits– Delivering value-for-money– Return-on-investment

• Ensure long-term availability of digital assets– Digital preservation and curation

A few words about metadata• Resources

– Digital– Physical– Item-level– Collection-level

• Services– Human-mediated– m2m– Common– Domain-specific

• Functions– Discovery– Management– Preservation & curation

• Metadata schema– e.g. Dublin Core, UK

LOM Core, METS

• Application profiles• Schema registries

– Publication– Mapping

3. Digital preservation & digital curation

Collaboration for Sustainability Conference 2004

19

Why advocate a digital preservation / curation policy?• Long-term access to digital assets• Preservation approaches

– Emulation, migration– LOCKSS– Universal Virtual Computer

• OAIS reference model• Preservation metadata• Provenance• Persistent identifiers

Technical Standards & Guidelines

• Document origins and influence– JISC Information Environment architecture– e-Government Interoperability Framework (e-GIF)

• Life-cycle approach– Creation, management, collection development, access,

repackaging

• Vocabulary– “must”, “should”, “may”

• Revisions– New standards– New guidelines on implementation– Latest version February 2003

• http://www.ukoln.ac.uk/nof/support/

Reporting & Compliance

• Working in partnership with BECTa• Compliance monitoring service• Quarterly reporting process

– Validation against published standards e.g. accessibility, (X)HTML conformance

– Difficult to assess all aspects– Valid reasons e.g. immature standards, lack of tools,

cost of implementation – Document with migration strategy

• Project sign-off– Pragmatic advice & recommendations

• Estimated >85% compliance

Observations

• Evolving technical landscape• Big issues

– Semantic interoperability– Persistent identifiers

• Awareness of new developments– e.g. NISO VIEWS Initiative

• Embedding standards (and skills)• Integrating within the workflow

Interoperability and innovation: a delicate balance

Thank you.
