  13. Why Share? • Sharing benefits users • One-stop searching (maybe) • Ability to create customized searches of specific domains • Brings together distributed collections • Sharing benefits your institution • Increases exposure of collections • Broadens user base • Potentially adds collaboration opportunities • We can no longer assume that users will come through the front door—sharing metadata gets us “in the flow” Missouri Library Association

  14. Sharing better allows our users to help us Missouri Library Association

  15. <title>My resource</title><date>04 <title>My resource</title><date>04 <title>My resource</title><date>04 Sharing metadata: Federated search The distributed databases are searched directly. Mill? For Example: Z39.50, SRU Missouri Library Association

  16. <title>My resource</title><date>04 Sharing metadata: Data aggregation The user searches a pre-aggregated database of metadata from diverse sources. Mill? For Example: Search engines, union catalogs, OAI PMH, RSS Missouri Library Association

  17. Some other options for sharing Missouri Library Association

  19. Today’s metadata aggregation environment • Users often discover material through shared records, not through your front door • Users don’t know about your collection or won’t remember it • Shared records lead users to local environment where full context is available • Because users enter through “deep” links, they may bypass introductory information that provides the larger context for a collection Missouri Library Association

  20. Finding the right balance • Metadata providers know the materials • Document encoding schemes, controlled vocabularies, and metadata creation practices • Ensure record validity • Aggregators have the processing power • Format conversion • Reconcile known vocabularies • Normalize data • Batch metadata enhancement Missouri Library Association

  21. Shareable Metadata… • Is quality metadata • Promotes search interoperability - “the ability to perform a search over diverse sets of metadata records and obtain meaningful results” (Priscilla Caplan) • Is human understandable outside of its local context • Is useful outside of its local context • Preferably is machine processable Missouri Library Association

  22. Shareable Metadata as a View • Metadata is not monolithic • Metadata should be a view projected from a single information object • Create multiple views appropriate for groups of important sharing venues • Depends on: • Use • Audience Missouri Library Association

  23. The Cs & Ss of Shareable Metadata Content Coherence Context Communication Consistency Conformance to Standards Missouri Library Association

  25. Basic metadata sharing workflow Transform Plan Choose standards for native metadata Perform conceptual mapping Create Share Assess Implement sharing protocol See who is collecting your metadata Who to share with? Perform technical mapping Create metadata (thinking about shareability) Communicate with aggregators Review your metadata in aggregations Choose shared metadata formats Validate transformed metadata Write metadata creation guidelines Test shared metadata with protocol conformance tools Missouri Library Association

  26. Three possible OAI-PMH workflows Digital asset management system MODS QDC Metadata creation module OAI data provider module Transformation DC MARCXML Metadata creation module Static Repository Gateway OAI Harvester Transformation QDC MODS Metadata creation system Stand-alone OAI data provider Transformation DC MARCXML Missouri Library Association

  27. Shareable metadata isn’t just about OAI-PMH • Some other options: • Lightweight APIs (e.g., OpenLibrary) • Google SiteMaps • OpenSearch • OpenURL • SRU • OAI-ORE • Linked data • Jim Michalko, RLG: library data sharing mechanisms are “high value and low participation” Notice Z39.50 isn’t on this list.

  28. Crosswalking – conceptual mapping Pathways to Digital Information - Crosswalks Missouri Library Association

  29. Crosswalking - XSLT Missouri Library Association

  30. Working around system limitations • Many digital asset management systems don’t support a second shareable copy of records • Do your best to split the difference with system records • Use creative interface design for your local system • Use extra-protocol documentation for communicating with aggregators • Lobby your vendor! Missouri Library Association

  31. Before you share… • Look at the record as the aggregator will see it • Appropriate view? • Consistent? • Context provided? • Does the aggregator have what they need? • Documented? Can a stranger tell you what the record describes? Missouri Library Association
