Transcript of "Increasing points of access – a guide to metadata harvesting"

  1. 1. Open Access MILE Conference London January 28 th 2009 A Picture’s Worth a Thousand Euros – Return on Investment? How to improve the cultural AND commercial potential of your image collection. Niamh Brennan Trinity College Dublin Garret McMahon Trinity College Dublin Increasing points of access – a guide to metadata harvesting
  2. 2. What’s the issue? <ul><li>“Providing the public with digital access to a collection of images is a necessity, but simply publishing them online doesn't make them accessible…” </li></ul><ul><li>- Charlotte Sexton, Deputy Head New Media, The National Gallery </li></ul>
  3. 3. Interoperability… What’s the solution? “… the ability of systems, services and organisations to work together seamlessly toward common or diverse goals”.
  4. 4. Interoperability for discovery of and access to images <ul><li>Requires OPEN STANDARDS for both </li></ul><ul><li>Communication between systems (digital archives, repositories, etc.) </li></ul><ul><li>and </li></ul><ul><li>2 . Description of resources and collections </li></ul>
  5. 5. OAI Metadata Harvesting – What is it? <ul><li>OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) is a protocol developed by the Open Archives Initiative </li></ul><ul><li>Based on standards that are Open and freely available </li></ul><ul><li>Can support any metadata schema </li></ul><ul><li>Can be incremental </li></ul><ul><li>Supports federated discovery services based on aggregated and shared metadata </li></ul>
  6. 9. What are they using? <ul><li>Open Archives Initiative (standard) compliant repositories </li></ul><ul><li>Agreed set of metadata </li></ul><ul><li>OAI Harvester (+ validator, aggregator) </li></ul><ul><li>Front end </li></ul>
  7. 10. OAI Harvesting: How it works
  8. 11. OAI Harvesting: How it works OAI Harvester Get List
  9. 12. Discovery of, and access to, images across distributed digital libraries/archives can be achieved easily and cost-effectively via metadata harvesting
  10. 13. Interoperability for discovery of and access to images <ul><li>Requires OPEN STANDARDS for both </li></ul><ul><li>Communication between systems (digital archives, repositories, etc.) </li></ul><ul><li>and </li></ul><ul><li>2 . Description of resources and collections </li></ul>
  11. 14. <ul><li>Research publications </li></ul><ul><li>Etheses </li></ul><ul><li>Epublishing/Grey Literature </li></ul><ul><li>Images </li></ul>
  12. 22. <ul><li>Higher Education Authority -funded under Strategic Innovation Fund </li></ul><ul><li>National Development Plan </li></ul><ul><li>Research as critical to economic development </li></ul><ul><li>National research profile </li></ul><ul><li>Managed by the Irish Universities Association </li></ul>IReL-Open Initiative
  13. 24. OAI Harvesting is not a panacea It needs help!
  14. 28. From: Sefton, Peter (2009) What the OAI-ORE protocol can do for you, [blog entry], PSetfton, 14/10/2008 http://ptsefton.com/2008/10/14/what-the-oai-ore-protocol-can-do-for-you.htm Australian University Repository Census (AUIRC) search Australian Research Repositories Online to the World (ARROW) search
  15. 33. Combined approach: <ul><li>Standardisation & mapping – agreement on same terms where possible </li></ul><ul><li>Dumbing down & mapping – exposure of lowest common denominator terms only eg 1 date field only </li></ul><ul><li>Normalisation at harvester end – harvester/validator automatically ‘understands’ and re-labels data </li></ul>
  16. 34. Agreement on a Core Set of Metadata Elements for harvesting <ul><li>Use Simple [i.e. unqualified] Dublin Core as the foundation for the Core Set </li></ul><ul><li>Ensure that the Core Set adequately represents the essential fields covered by the major metadata schemas </li></ul><ul><li>Keep the number of mandatory fields to a minimum </li></ul><ul><li>Map the corresponding element/s in richer metadata schemas used locally to the elements in the Core Set </li></ul><ul><li>Expose only the elements corresponding to the Core Set for harvesting </li></ul><ul><li>At the local level document the mapping [cross-walk] used (eg. CDWAlite to Dublin Core, VRA Core to Dublin Core) and which elements are exposed for harvesting </li></ul>

  19. 37. Where is the Value? <ul><li>Maximum impact & exposure – works for commercial agencies and for publicly-funded institutions </li></ul><ul><li>Lightweight, easy implementation </li></ul><ul><li>Re-use of expensively created metadata for multiple purposes </li></ul><ul><li>Local control /national, international, specialist applications </li></ul>
  20. 38. Interoperability… What’s the solution? “… the ability of systems, services and organisations to work together seamlessly toward common or diverse goals”.
