  • Ands National Identifier Solution

    1. 1. The ANDS “Identify My Data” service and related issues Andrew Treloar, ANDS JISC Research Identifier Workshop 3 Feb 2010, London
    2. 2. Australian National Data Service (ANDS) <ul><li>An initiative of the Australian Government being conducted as part of the National Collaborative Research Infrastructure Strategy ($A24M) and the Super Science Initiative ($A48M) </li></ul><ul><li>A collaboration between Monash University, the Australian National University and CSIRO </li></ul><ul><li>Operations nodes in Melbourne, Canberra, and elsewhere </li></ul><ul><li>About 40 staff, and growing </li></ul>
    3. 3. What does ANDS do? <ul><li>Establish the Australian Research Data Commons </li></ul><ul><ul><li>A shared data space </li></ul></ul><ul><ul><li>Collaborative research </li></ul></ul><ul><ul><li>Distributed model </li></ul></ul><ul><ul><li>Data stewardship </li></ul></ul><ul><ul><li>Interoperability and access </li></ul></ul><ul><li>Vision: ‘More researchers re-using more data more often’ </li></ul>
    4. 4. Australian Research Data Commons
    5. 5. Why make data public? <ul><li>Funding guidelines </li></ul><ul><ul><li>publicly funded research </li></ul></ul><ul><ul><li>avoid duplication </li></ul></ul><ul><ul><li>encourage re-use </li></ul></ul><ul><li>Open research </li></ul><ul><ul><li>verification of claims </li></ul></ul><ul><ul><li>available for re-analysis </li></ul></ul><ul><li>Longitudinal studies </li></ul><ul><li>Collaboration, mash-ups, linking data… </li></ul>
    6. 6. Publishing Data Benefits <ul><li>Acknowledgement for the creator/ publisher </li></ul><ul><li>Stable part of scholarly communication </li></ul>
    7. 7. Publishing and Scholarly Comm’n <ul><li>Registration (to resolve questions of precedence) </li></ul><ul><li>Certification (of the validity of a scholarly claim) </li></ul><ul><li>Awareness (to ensure that scholars are kept aware of new work) </li></ul><ul><li>Archiving (to preserve the scholarly record over time) </li></ul><ul><li>Rewarding (for measured performance according to discipline or system-specific metrics) </li></ul><ul><li>Roosendaal, H., and Geurts, P. 1997, ‘Forces and functions in scientific communication: an analysis of their interplay’, Cooperative Research Information Systems in Physics , August 31—September 4, Oldenburg, Germany. </li></ul>
    8. 8. Data and Publications <ul><li>Traditionally data has been a means to generate a publication (or part of it) </li></ul><ul><li>ANDS wants to see data as a first class object, with equal (but different) status </li></ul>
    9. 9. ANDS Data Sharing Verbs <ul><li>Create </li></ul><ul><li>Store </li></ul><ul><li>Describe </li></ul><ul><li>Register </li></ul><ul><li>Identify </li></ul><ul><li>Discover </li></ul><ul><li>Access </li></ul><ul><li>Exploit </li></ul>research group data facility group consumer group
    10. 10. Create Store Describe Register Identify Discover Access Exploit Monolithic eResearch or Repository Application
    11. 11. <ul><li>Identify My Data – allocate a persistent identifier </li></ul><ul><li>Register My Data – register a public collection description with contextual information </li></ul><ul><li>Research Data Australia – discover browse, explore a mesh of data collections and the people, research organisations, and services </li></ul><ul><li>Publish My Data – the lot! </li></ul>Describe Register Identify Discover
    12. 12. ANDS Services <ul><li>Online </li></ul><ul><ul><li>Available to users on the Web </li></ul></ul><ul><li>Web services </li></ul><ul><ul><li>Designed for machine-to-machine transactions </li></ul></ul>
    13. 13. ANDS Identify my Data <ul><li>Allows researchers or their organisations to allocate persistent identifiers to datasets. </li></ul><ul><li>Why? </li></ul><ul><ul><li>What happens to the published references to your datasets when your Department changes name? </li></ul></ul><ul><ul><li>Or your data store software completely changes platforms? </li></ul></ul><ul><ul><li>Or your webserver re-arranges its directory hierarchy? </li></ul></ul>
    14. 14. What is a persistent identifier? <ul><li>A URL says where something is </li></ul><ul><li>Problem if the thing is moved: need to tell everyone </li></ul><ul><li>A PID says where to look for where the location of the thing is written </li></ul><ul><li>ANDS provides a place to write that location </li></ul><ul><li>Now if the thing moves, the PID stays the same, and the location only has to be updated in one place </li></ul>
    15. 15. Four kinds of persistence <ul><li>identifier </li></ul><ul><ul><li>text string – won’t expire </li></ul></ul><ul><li>resolution </li></ul><ul><ul><li>ability to get from identifier to object </li></ul></ul><ul><li>binding/mapping </li></ul><ul><ul><li>relationship between identifier and object </li></ul></ul><ul><li>object </li></ul><ul><ul><li>in its storage system </li></ul></ul>
    16. 16. Managing persistent identifiers <ul><li>If one has a PID, someone has to manage it. </li></ul><ul><li>ANDS provides the infrastructure to enable machines/people to update the location information when data is moved </li></ul><ul><li>NOTE: Software is not a solution to the human problem, or the need for ongoing responsibility for PIDS </li></ul>

    18. 18. Nuts and Bolts <ul><li>Identifier = 102.100.100/243 </li></ul><ul><li>ANDS is part of the global Handle infrastructure to resolve persistent identifiers </li></ul><ul><ul><li> 102.100.100/ 243 </li></ul></ul><ul><li>ANDS has just joined DataCite, and will this year start offering DOIs for published, citable data </li></ul><ul><li>In effect, this is a Basic+Premium service offering </li></ul>
