For later use? In use now (and the future)?

Repositories and digital curation

Data preservation Data curation

Static Dynamic

“maintaining and adding value to a trusted body of digital information for current and future use”

3

Digital | Curation | Centre

Assuring permanent access to the records of science & the humanities?

Long term access to primary data

• Increasing data volumes from eScience and Grid-enabled / cyberinfrastructure applications

• Changing research paradigm: data-driven science, “big science”

• Observational data, simulations, large-scale experimentation

• Multi-media resources, statistical data, surveys, geo-spatial data……

4

Digital | Curation | Centre

Facilitate “post-processing” and knowledge extraction

Enable the acquisition of newly-derived information and knowledge

• Run complex algorithms over primary datasets

• Mining (data, text, structures)

• Modelling (economic, climate, mathematical, biological)

• Analysis (statistical, lexical, pattern matching, gene)

• Presentation (visualisation, rendering)

5

Digital | Curation | Centre

6

Digital | Curation | Centre

Provide additional functionality beyond digital preservation processes: adding value

Annotations

• Gene and protein sequences

• e-Lab books (Smart Tea Project in chemistry)

Research & e-Science workflows

Aggregator services: national, commercial

Repositories : institutional, e-prints, subject, data, learning objects

Data curation: databases & databanks

Validation

Harvestingmetadata

Data creation / capture / gathering: laboratory experiments, Grids, fieldwork, surveys, media

Deposit / self-archiving

Peer-reviewed publications: journals, conference proceedings

Publication

Validation

Data analysis, transformation, mining, modelling

Searching , harvesting, embedding

Presentation services: subject, media-specific, data, commercial portals

Resource discovery, linking, embedding

Linking

The scholarly knowledge cycle : linking research data to publications

Emerging policy on open access to data

Digital | Curation | Centre

Issues: generic data models, metadata schema & terminology

• Validation against other schema• Complex digital objects and packaging options

– METS– MPEG 21 DIDL

• Terminologies– Domain: marine?– Inter-disciplinary e.g. wider environment, bio….– Metadata and vocabularies– Meaningful resource discovery?

9

Digital | Curation | Centre

Ontologies for discovery in an interdisciplinary world

• Transform the ‘list’ into an ‘ontology’

• Embed ontology into the deposition process

• Aggregators use keywords for linking with the broader literature

• Researchers use keyword ontology in search and discovery services

• Formal vs informal “folksonomies”

• Web 2.0???

10

Digital | Curation | Centre

Issues: Persistent identifiers for data (image) citation

• Use cases: depositor, author, service provider, reader, publisher, ?

• Schemes: DOI, Handle, ARK, PURL• Global identification: express as http URIs• Added value services: CrossRef, resolution

service, integration (Globus), look-up service, ?• Degree of trust or persistence• Costs• Future potential: political, ?• Domain identifiers: e.g. International Chemical

Identifier (InChI) codes

11

Digital | Curation | Centre

Issues: Integration into (marine) research workflows

• R4L Repository for the Laboratory Project (JISC-funded) automated data capture from instrumentation, registration of results

• SMART TEA electronic Laboratory notebook + annotations

• Publishers??• Research assessment (RAE) process?

DCC: Development

• “DCC Approach to Digital Curation” based on the Reference Model for an Open Archival Information System (OAIS); ISO standard, 14721:

– Monitoring international standards– Development of a Representation Information

(RI) registry/repository (DCC-RR)– Recommendations for tools and methods for

generating Representation Information– Creating test-beds for digital curation tools
