Doomed data http://www.learnin gcurve.gov.uk/foc uson/domesday/ta ke-a-closer-look/In the vill in which St. Peter’s Church is situated [Westminster] the abbot of the sameplace holds 13½ hides. There is land for 11 ploughs. To the demesne belongs 9 hidesand 1 virgate, and there are 4 ploughs. The villeins have 6 ploughs, and there could be 1plough more. There are 9 villeins each on 1 virgate and 1 villein on 1 hide, and 9 villeinson each half a virgate and 1 cottar on 5 acres, and 41 cottars who pay 40 shillings ayear for their gardens. [There is] Meadow for 11 ploughs, pasture for the livestock of thevill, woodland for 100 pigs, and 25 houses of the abbot’s knights and other men who pay8 shillings a year. In all it is worth £10; when received, the same; TRE £12. This manor

Missing negative data• Need title capture for negative results
“Selective Publication of Antidepressant Trials and ItsInfluence on Apparent Efficacy”Turner, Erick, Matthews, Annette, Linardatos, Eftihia,Tell, Robert, Rosenthal, Robert.New England Journal of Medicine. 358(3):252-260,January 17, 2008.From the Abstract:“Evidence-based medicine is valuable to the extent thatthe evidence base is complete and unbiased. Selectivepublication of clinical trials - and the outcomes withinthose trials - can lead to unrealistic estimates of drugeffectiveness and alter the apparent risk-benefit ratio”
Why is data now so important?• We are in an era of increasing data-intensive research• Almost all data is now born digital• Increasing amount of data generated (semi-)automatically• “Consequently, increasing effort and therefore funding will necessarily be diverted to data and data management over time” – Towards the Australian Data Commons, p. 4 (http://www.pfc.org.au/bin/view/Main/Data) 19
Need for standardisation• Software and silicon-based hardware keep getting cheaper, carbon-based wetware keeps getting more expensive• Fixing data management problems is enormously labour intensive and costly• “Consequently, standardisation within forms of data and simplification in the frameworks around retention, storage, access and use of data, and the elimination of differences whose resolution requires labour, must be made, if the on-going keeping and reuse of data is to remain affordable” – Towards the Australian Data Commons, p. 5 20
Role of data federations• With more data online, more can be done• Possible now to answer questions unrelated to reasons why data was collected originally• Increasing focus on cross-disciplinary science• “Consequently greater clarity is needed over control and access to community-funded data, and the means of aggregating, federating and accessing such data are increasingly important” – Towards the Australian Data Commons, p. 5 21
Changing Data, Changing Research• New scientific instruments – Large Hadron Collider at CERN: 1.5 GB/sec – Square Kilometre Array telescope: 1 EB/day! • Exabyte = a thousand million gigabytes (1018 bytes)• New scientific Models – The mapping of the Human Genome: A billion DNA letters in a human sequence – Global climate models: ever finer time/space resolution• New knowledge from unlocked data – Hubble data has to be shared six months after collection – Majority of published research from Hubble telescope data was not “first use” 22
Data desiderata• Easy deposit for researchers• Greater (preferably open) access for all• Easier (or any!) citability• Easier discoverability, particularly outside generating discipline• More context for those outside the generating discipline
A partial solution:data in institutional repositories
Another partial solution:researcher workflow integration

Australian National Data Service• Funded by Australian Government at A$21M from mid-2008 through mid-2011• Goal: to deliver greater access to Australia’s research data assets in forms that support easier and more effective data use and reuse• Approach: building the Australian Research Data Commons
ANDS Delivery Structure• ANDS has been structured as four inter- related and co-ordinated service delivery programs: – Developing Frameworks (policy, planning) – Providing Utilities (discovery, persistent ID) – Seeding the Commons (more data, better managed) – Building Capabilities (researcher and support)• Plus candidate service development activities funded through a discipline-driven 40
Conclusion• Data is becoming steadily more important for research• Research results need to be communicated• Data is the next great challenge for scholarly communication• And so, it should be the next great challenge for libraries• Over to you!
