UK DATA ARCHIVE
WHO WE ARE
• Established in 1968 - 46 years of selecting, curating, preserving and providing access to social science data
• 6,000 datasets in the collection• Over 25,000 registered users
• Data and data support services for higher and further education for research, teaching and learning
• Have been registered to ISO 27001 (information security standard) since June 2010
……………………………………………………………………………………………………………………………….……………………………
…………………………………………………………………………………………………………………………………………………………………
UK DATA ARCHIVE
OUR SERVICES
• UK Data Archive itself a department of the University of Essex
• Distributed service established 1 January 2003 called the Economic and Social Data Service (ESDS)
• New five-year UK Data Service from 2012
……………………………………………………………………………………………………………………………….……………………………
…………………………………………………………………………………………………………………………………………………………………
UK DATA ARCHIVE
WHAT WE DO
• Research & development, innovation • Promoting best practice in data curation
• Raise standards in data security and awareness of ethical/legal issues
• Raise standards in data management• Data management hub• We provide guidance to ESRC
researchers and anyone else who asks

ENGAGEMENT WITH RDM COMMUNITY
• Recently completed JISC Managing Research Data project with University of Essex
• Cross support service, departmental engagement• Piloted an RDM infrastructure• http://www.data-archive.ac.uk/create-manage/proj
ects/rd-essex
• Outputs of value to RDM community:• Metadata profile for institutional data
repositories• Research data plugin for EPrints

WHY CITE DATA?
It’s a vital part of a rigorous research process:
• Acknowledges researcher’s sources • Gives data creators, authors and data
curators proper credit when their work is reused
• Facilitates data resource discovery and access
• Helps track the use and impact of data collections

OUR APPROACH TO CITATION
• Required by our user agreement (End User Licence) for many years:
……………………………………………………………………………………………………………………………….……………………………
…………………………………………………………………………………………………………………………………………………………………
UK DATA ARCHIVE
OUR APPROACH TO CITATION
• Should include enough information to ensure the exact version can be located
“University of Essex. Institute for Social and Economic Research and National Centre for Social Research, Understanding Society: Wave 1, 2009-2010 [computer file]. 2nd Edition. Colchester, Essex: UK Data Archive [distributor], November 2011. SN: 6614.”
• No widely agreed standard citation format yet!• Version information crucial
……………………………………………………………………………………………………………………………….……………………………

UK DATA ARCHIVE
PERSISTENT IDENTIFERS
• Persistent Identifiers (PIDs) • A string identifying a clearly
defined digital object• Persistence must mean enduring• Identifiers must be unique
• PIDs have been attached to scientific publications for some time
• Next logical step: data• Also being applied to other entities
e.g. people via ORCID system
……………………………………………………………………………………………………………………………….……………………………

UK DATA ARCHIVE
CHANGES TO DATA
• Our ‘data collections’ are not discrete digital objects
• Approx. 15% UKDA data collections are altered within first year after publication
• Versioning - we need to distinguish between major and minor changes to a data collection
• Integrate processes with:• Digital preservation activities• Current ingest infrastructure / workflows
……………………………………………………………………………………………………………………………….……………………………
…………………………………………………………………………………………………………………………………………………………………
UK DATA ARCHIVE
MINOR CHANGES – LOW IMPACT
• Publication reference added• Correction of spelling in variable
labels• Small changes in variable labels• Removal of (erroneously
supplied) admin variables• Correction of spelling in
metadata• Minor changes in documentation• New index (keyword) terms• Additional documentation added
(non-fundamental)• Change in access conditions
……………………………………………………………………………………………………………………………….……………………………
…………………………………………………………………………………………………………………………………………………………………
UK DATA ARCHIVE
MAJOR CHANGES – HIGH IMPACT
• Adding new ‘waves’ in a data series
• New variable added
• New labels/value codes added
• Weighting variables reconstructed
• Wrong data supplied (e.g., March not April)
• Mis-coded data (e.g., Don’t know/Refused mix-up)
• Change in format (file migration)
• Significant changes in documentation
• Change in access conditions

DATACITE DOIs
• 2011: we started working with the British Library and DataCite to develop a permanent, reliable method of citing our data collections
• DataCite • Founded by organisations from six
countries• Established a citation format for research
data, including a DOI• Works with data publishers, e.g.
established data centres and institutional repositories
……………………………………………………………………………………………………………………………….……………………………
…………………………………………………………………………………………………………………………………………………………………
UK DATA ARCHIVE
WHY DATACITE?
Not the only choice, but right for us:• DOI framework an international and persistent
standard for identifying digital objects
• Familiar within the research data domain
• Centralised resolution service
• Metadata registry (and thus de facto standard)
• Discovery link up
• API – allowing for automation of minting process (but also manual if you prefer!)

CHALLENGES FOR THE FUTURE
• Citing parts (fragments) of data collections• single files• subsets of quantitative data files • extracts of textual data
• Still uncertainty over where exactly research data should go – IR, Subject Specific Repository, Data Journal?• Who should be minting DOIs?• Avoid assigning multiple identifiers to an object
