research to learning
• Access and re-use of scholarly materials
• Added value services on scholarly
materials (involving HE and commercial
sectors)

• Rich data flow between networks of
repositories
• Rich data flows between repositories and
other components in information landscape

New forms of
publication:

journals
Emerging ecology
Defining workflows and dataflows
• Analyse roles and interactions within and
beween repositories
• What does the user want?
• Identify and define services
– Potential for ‘shared services’, re-use of
services
• Explore potential dataflows
– Aggregation, data exchange, metadata
extraction and enhancement
Dataflows and Workflows
• How is primary research data captured
in faculty and academic departments?
• Where and how is primary research data
stored? Made accessible?
• What are processes for deriving further
data and how is this is structured and
stored? Made accessible?
• How is data curated for the long term?
Understanding the research 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 and workflow
• DCC SCARP
– Curation staff working within research teams

Data capture
Digital repositories, OA & preservation
• Long-term access: trust, responsibility, policy
• Trusted DR Audit Checklist for Certification Draft Research
Libraries Group-NARA Taskforce 2005
• Defined criteria under 4 categories
–

Organisation
Functions, processes & procedures
Designated community & usability
Technologies & technical infrastructure
• UK Digital Curation Centre: advice, tools & services

• RepInfo Registry
• EU CASPAR Integrated Project
http://www.casparpreserves.info/pages/1/index.htm
• Task Force on the Permanent Access to the Records of
Science
http://tfpa.kb.nl/
Data, metadata and discovery
• Validation, publication & discovery of
data models & schema
• Metadata packaging standards
– METS, MPEG 21 DIDL
– Complex object model?
• Semantic descriptions
– Formal high-level and domain ontologies
– Inter-disciplinary discovery
• ePrints DC Application Profile
• UK Intute IR search service (eprints)
• Informal social network approaches
“folksonomies”
• What data models and metadata
schema are in place?
• Have librarians been involved in
their development?
Persistent identifiers for data citation
• How will they be used? We need use cases: depositor,
author, service provider, researcher, publisher?
• Schemes: DOI, Handle, ARK, PURL
• Publication & citation of scientific primary data project
National Library for Science & Technology (TIB), University
of Hanover, Germany. STD-DOI Project DOI registry for
datasets http://www.std-doi.de
• What persistent
identifiers have been
assigned to your data?
• Is there a data
citation policy?
• Was the Library
involved?
Adding value: repository services
• Tools: for deposit, normalisation,
manipulation, transformation…..
• Linking, annotation, visualisation
• Aggregators: generic, (sub-)
disciplinary
Knowledge extraction:
• Mining (data, text, structures)
• Modelling (economic, climate,
mathematical, biological…)
• Analysis (statistical, lexical, gene….)
Is your data OA?
How is your data being used
and re-used?

Retrieve and follow instructions (sub-workflow?)
Experimental synthesis metadata automatically recorded on instruments
(Smart Lab)
Create record for synthesised sample (+ proposed chemical identifier) in
R4L laboratory data management system
Run spectral analyses on sample capturing further analysis metadata
(incl. time-stamp, analysis software version, researcher details etc.)
Save spectrum in native and common formats
Invoke R4L data capture service and deposit files + metadata in
laboratory repository…

eBank UK Project
http://www.ukoln.ac.uk/projects/ebank-uk/
• 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

service in a science portal for student learners
Integration into the curriculum and eLearning workflows
• MChem course
• Assess role in
Undergraduate

open access to and re-use of scholarly
materials
• Integrated life-cycle of knowledge from
research to learning
• Available metadata about scholarly
materials
• Added value services on scholarly
materials (involving HE and commercial
sectors)
More repositories and more content!
• Working papers, primary data, audiovisual,

• Hardware in research labs will
automatically deposit experimental data
• Desktop tools will deposit content
• Rich data flow between networks of

Defining workflows and dataflows
• Analyse roles and interactions within and
beween repositories
• What does the user want?
• Identify and define services
– Potential for ‘shared services’, re-use of
services
– In context of JISC e-Framework
• Explore potential dataflows
– Aggregation, data exchange, metadata
extraction and enhancement
Deposit a priority!
• To enable users to populate repositories simply,
effectively and preferably automatically
• To capture content from desktop applications,
experimental equipment (smart labs), learning
content development tools etc
• To enable repository of deposit to exchange data
with further repositories in predictable manner
• To hide complexity from end-user
• To be compatible with follow-on added value
services layered on repository content
• Deposit API Working group meeting July 11/12,
Warwick
