• Multi-disciplinary, cross-sectoral
• National, institutional
• Different platforms
• Many format types: data, eprints, images, geospatial
• e-Framework and Information Environment context
• Define common + domain-specific + repository “services”
• Interoperability based on open standards, software tools

Update on JISC DR activity 1• Commissioned reports: Review (Feb 2005), Roadmap (April
2006), Linking UK Repositories (June 2006)• £4M DR Programme 2005
– 21 Projects: some working with data, VERSIONS (of eprints)
• DR support at UKOLN : wiki http://www.ukoln.ac.uk/repositories/digirep/index/JISC_Digital_Repository_Wiki
– Advocacy Package (autumn 2006)– Project synthesis, collecting user scenarios, developing use cases,
scoping/evaluating reference models: OAIS?– Standards (and harmonisation)– ePrints Dublin Core Application Profile Working Group– “Remote deposit” API Working Group (Mellon New York meeting)
• UK IR cross search service (eprints)

e-Research: understanding business process
• Project StORe: Source-to-Output Repositories (Edinburgh) – primary data : research publications– Survey questionnaire
• RepoMMan: Repository Metadata and Management (Hull)– Survey questionnaire and interviews– Activity diagram
• R4L Repository for the Laboratory (Southampton)– Crystallography workflow analysis, automated
data capture, user deposit scenariosRAW DATA DERIVED DATA RESULTS DATA

eBank UK Project• Promote open access crystallography data • Aggregator service harvests OAI metadata from institutional data
repository (e-Crystals archive)• Service linking from data to derived research publication• Embedding eBank service in learning workflows: pedagogy• Future federation plans for crystallography data repositories

eBank Metadata Publication• Using simple Dublin Core
• Crystal structure• Title (Systematic IUPAC Name)• Authors• Affiliation• Creation Date
• Additional chemical information through Qualified Dublin Core• Empirical formula• International Chemical Identifier InChI • Compound Class & Keywords
• Specifies which ‘datasets’ are present in an entry• Application Profile• DOIs, data citation http://dx.doi.org/10.1594/ecrystals.chem.soton.ac.uk/145

Discovering data:
Coles, S.J., Day, N.E., Murray-Rust, P., Rzepa, H.S., Zhang, Y., Org. Biomol. Chem., 2005, (10),1832-1834. DOI: 10.1039/b502828k
• Domain identifier: International Chemical Identifier (INChI) code• Google molecule using INChISlide from Simon Coles

www.ukoln.ac.uk
Data descriptions• Validation, publication & discovery
of data models & schema• Metadata packaging standards
– METS– MPEG 21 DIDL– Complex object model?
• Semantic descriptions– Formal controlled vocabularies– High-level and domain ontologies– Inter-disciplinary discovery
• Informal social network approaches “folksonomies”

Adding value: repository services• Tools: for deposit, normalisation, manipulation, transformation…..
• Linking, annotation, visualisation
• Aggregators: generic, (sub-) disciplinary
• Knowledge extraction:
Mining (data, text, structures) National Centre for Text Mining NaCTeM
Modelling (economic, climate, mathematical, biological…)
Analysis (statistical, lexical, gene….)

JISC DR update 2• OpenDOAR Directory of Open Access repositories: Universities
of Nottingham and Lund• “Interim” Repository• Access management systems integration: Shibboleth• New funding 2006: Capital Programme Roadmap, Repositories
& Preservation Programme– £14M over 3 years but current Call:– Repositories Support Project– Tools & Innovation Strand– Discovery to Delivery Strand
• Data Curation and Preservation

www.ukoln.ac.uk
Digital repositories, OA & preservation• Long-term access: trust, responsibility, policy• Trusted DR Audit Checklist for Certification Draft Research
Libraries Group-NARA Taskforce • Defined criteria under 4 categories
– Organisation– Functions, processes & procedures– Designated community & usability– Technologies & technical infrastructure
• UK Digital Curation Centre: advice, tools & services• RepInfo Registry• CASPAR Preservation Framework

Political, cultural, socio-legal, IPR
• Funding bodies position on OA: Research Councils RCUK statement, Research Assessment Exercise (RAE), IRRA
• Institutional OA position: – Business drivers? University of Southampton Self-Archiving Policy and a
mandate (not a recommendation)– Legal responsibilities as publisher, IPR, TrustDR, licences, automated Digital
Rights Management DRM
• Culture & human factors: – “Sharing culture?” – Multidisciplinary teams: computer scientists, domain scientists, digital library
experts, statisticians/modellers e.g. eBank project– Lessons learnt: e-Science Human Factors Audit Report (to be published
