The Dynamics of Sharing: An Introduction to Shareable Metadata and Interoperability

  1. The Dynamics of Sharing Introduction to Shareable Metadata and Interoperability Sarah L. Shreeves University of Illinois at Urbana-Champaign August 31, 2007 The Dynamics in the Aggregate: Shareable Metadata and Next-Generation Access Systems SAA 2007 – Chicago, Il
  2. Assumptions
  3. Why Share? <ul><li>Sharing benefits users </li></ul><ul><ul><li>One-stop searching (maybe) </li></ul></ul><ul><ul><li>Ability to create customized searches of specific domains </li></ul></ul><ul><ul><li>Brings together distributed collections </li></ul></ul><ul><ul><li>Ability for USERS to create their own mash-ups of metadata from different sources </li></ul></ul><ul><li>Sharing benefits us </li></ul><ul><ul><li>Increases exposure of collections </li></ul></ul><ul><ul><li>Broadens user base </li></ul></ul><ul><ul><li>Potentially adds collaboration opportunities </li></ul></ul>
  4. Why Share? <ul><li>Fundamentally we can no longer assume that users will come through the front door, so sharing metadata gets us “in the flow”. </li></ul>
  5. Keys to Shareability or Interoperability <ul><li>Communication protocol (Z39.50, OAI PMH, RSS, etc.) </li></ul><ul><li>Organizational commitment </li></ul><ul><li>Standards </li></ul><ul><li>Standards </li></ul><ul><li>And more Standards </li></ul>
  6. Sharing metadata: Federated search <ul><li>The distributed databases are searched directly. </li></ul>Mill? For Example: Z39.50, SRU <title>My resource</title> <date>04 <title>My resource</title> <date>04 <title>My resource</title> <date>04
  7. Sharing metadata: Metadata aggregation <ul><li>The user searches a pre-aggregated database or brings together metadata from diverse sources. </li></ul>Mill? For Example: Search engines, union catalogs, OAI PMH, RSS, Atom <title>My resource</title> <date>04
  8. OAI List Records Request
  9. Metadata challenge <ul><li>“the ability to perform a search over diverse sets of metadata records and obtain meaningful results .” </li></ul><ul><li>– Priscilla Caplan </li></ul><ul><li>Metadata Fundamentals for All Librarians </li></ul>
  10. Example <ul><li>Title: China Association </li></ul><ul><li>Author/Creator: China Association </li></ul><ul><li>Publisher: School of Oriental and African Studies </li></ul><ul><li>Year: 2002-04-23 </li></ul><ul><li>Resource Type: text </li></ul><ul><li>Resource Format: text/html </li></ul><ul><li>Description: Papers, 1889-1969, of the China Association, including minutes and committee papers of the General Committee and Executive Committee; correspondence with the Foreign Office, Board of Trade, Sino-British Trade Council, Tientsin and Hong Kong Chambers of Commerce, Hong Kong Association and the British Consulate in Shanghai; annual reports (1889-1962); and separate items including the minutes and papers of the China Association's School of Practical Chinese Endowment Fund (1908-1955). Also includes committee papers and minutes of the British Chambers of Commerce in Hankow and Tientsin, the Hong Kong Association, the Sino-British Trade Council, and the British Residents' Association in Shanghai. Also includes photographs of banquets (1896-1906), and albums of newspaper cuttings on China (1940-1947) and Japan (1942-1949). </li></ul><ul><li>Subject: Asian languages; Chinese; Foreign relations; International relations; International trade; Language instruction; Newspaper press; Photographs; Press; Press cuttings; Second language instruction; South and Southeast Asian languages; Trade; Trade policy; Visual materials    </li></ul><ul><li>URL: http://www.archives.uk/cats/19/65.htm </li></ul><ul><li>Rights: Unrestricted.

  12. Examples <ul><li>title: (Woman Holding a Pie) LNG42122.5 </li></ul><ul><li>subject: Berkeley; male; outdoors; yard; stair </li></ul><ul><li>subject: Dorothea Lange Collection </li></ul><ul><li>subject: The War Years (1942-1944) </li></ul><ul><li>subject: Office of War Information (OWI) </li></ul><ul><li>subject: Woman Holding a Pie </li></ul><ul><li>publisher: Museum of [state] </li></ul><ul><li>date: 1944 </li></ul><ul><li>type: image </li></ul><ul><li>identifier: http://www.orgname.org/idnumber </li></ul><ul><li>relation: http://orgname.org/findaid/idnumber </li></ul><ul><li>relation: id:/13030/tf9779p783 </li></ul><ul><li>relation: http://www.orgname.org/ </li></ul><ul><li>relation: http://findaid.org.org/findaid/... </li></ul><ul><li>relation: http://www.orgname.edu/project/ </li></ul>Dublin Core record harvested via OAI
  13.  
  14. Metadata as a View <ul><li>Metadata is not monolithic </li></ul><ul><li>Metadata should be a view projected from a single information object. </li></ul><ul><li>Create multiple views appropriate for different venues </li></ul><ul><li>Affects: </li></ul><ul><ul><li>Granularity of Description </li></ul></ul><ul><ul><li>Choice of vocabularies </li></ul></ul><ul><ul><li>Choice of formats </li></ul></ul>
  15. What is Shareable Metadata? <ul><li>Is quality metadata </li></ul><ul><li>Promotes search interoperability </li></ul><ul><li>Is human understandable outside of its local context </li></ul><ul><li>Is useful outside of its local context </li></ul><ul><li>Preferably is machine processable </li></ul>
  16. Shareable Metadata also… <ul><li>Provides enough contextual information </li></ul><ul><li>Is consistent across a collection </li></ul><ul><li>Is coherent </li></ul><ul><li>Is true to its content but also its audience </li></ul><ul><li>Conforms to standards </li></ul>
  17. Safe Assumptions <ul><li>Users often discover material through shared records, not through your front door </li></ul><ul><li>Users don’t know about your collection or won’t remember it. </li></ul><ul><li>Shared records lead users to local environment where full context is available </li></ul><ul><li>Because users enter through “deep” links, they may bypass introductory information that provides the larger context for a collection. </li></ul>
