Future Of Metadata –

  1. 1. Future of Metadata <ul><li>Jill Strass </li></ul><ul><li>October 1, 2007 </li></ul>
  2. 2. Where is metadata going? <ul><li>Metadata Golden Rule: When content and record become one entity, content providers will determine the nature of metadata. </li></ul>
  3. 3. Where does metadata come from? <ul><li>MARC21 or existing standards </li></ul><ul><li>Content providers – i.e. EBSCO </li></ul><ul><li>Free on the Internet – i.e. Bartleby and Gutenberg </li></ul><ul><li>Homegrown metadata – custom-made databases specific to organizations </li></ul><ul><li>Database administrator’s role in metadata creation </li></ul>
  4. 4. Database admin and metadata <ul><li>Naming fields (creating metadata) </li></ul><ul><li>Designing databases </li></ul><ul><li>Creating conceptual schemas (either on purpose or incidentally) </li></ul><ul><li>Creating indexes </li></ul>
  5. 5. Possible metadata futures <ul><ul><ul><li>Data fiefdoms and tower of Babel effect </li></ul></ul></ul><ul><ul><ul><li>Metadata thesaurus </li></ul></ul></ul><ul><ul><ul><li>Utopian paradise of correctly modified and applied standards that evolve in perfect pace with technological change. </li></ul></ul></ul><ul><ul><ul><li>Probable reality of multiple, concurrent standards in competition with each other (like VHS and Beta). </li></ul></ul></ul>
  6. 6. Metadata thesaurus: a solution to the Tower of Babel effect <ul><li>Acts as a translation mechanism between standards by classifying data elements and matching their equivalents. </li></ul><ul><li>Would allow multiple standards to co-exist </li></ul><ul><li>Would require significant investment in time; cooperation with vendors; and/or frequent close inspection of data fields used by vendors. </li></ul>
  7. 7. Is the catalog still relevant? <ul><li>What goes in the catalog? – If electronic content replaces books, where do we draw the line? Why not just have users search licensed databases? </li></ul><ul><li>The future catalog </li></ul><ul><ul><li>Points to content </li></ul></ul><ul><ul><li>Provides content </li></ul></ul><ul><li>Librarians as editors – Putting content into context for users (Wikis, If-you-like databases as in Amazon and some library catalogs) </li></ul>
  8. 8. Librarians as Editors – Use metadata to put info in context for users <ul><li>Most library sites only offer lists of links </li></ul><ul><li>Wikis allow us to offer information in context </li></ul><ul><li>St Joseph Indiana Public Library uses Wikipedia format to give offered links a context </li></ul><ul><li>http://www.libraryforlife.org/subjectguides/index.php/Jobs </li></ul><ul><li>Creating this kind of content is much easier with appropriate metadata </li></ul>
  9. 9. Slimming the hit list <ul><ul><ul><li>FRBR </li></ul></ul></ul><ul><ul><ul><li>Records need to be considered for weeding, just like books, not because they take up space on a server, but because old records that aren’t useful take up valuable real estate on a hit list. </li></ul></ul></ul><ul><ul><ul><ul><li>Temporary records from botched circ transactions </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Vendor records (On-order records) </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Content that resides on someone else’s server: Licensing and ownership issues (licensed databases and flaky websites) </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Weeding (if we put it in, when do we pull it out?) </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Leading users to the best resource for their search </li></ul></ul></ul></ul>
  10. 10. Conceptual Schemas and Search <ul><ul><li>Customizing the data to fit the search engine and vice-versa </li></ul></ul><ul><ul><li>Relational vs. flat file </li></ul></ul><ul><ul><li>Advanced search functions </li></ul></ul><ul><ul><ul><li>Field-based search </li></ul></ul></ul><ul><ul><ul><li>Popularity engines like Google </li></ul></ul></ul><ul><ul><ul><li>Site-based engines like Rollyo </li></ul></ul></ul><ul><ul><ul><li>Federated search </li></ul></ul></ul>
  11. 11. Search interfaces <ul><li>Aquabrowser – browse-friendly searching </li></ul><ul><li>Field-based search – finding specific information </li></ul><ul><li>Alternatives to text-based search </li></ul><ul><ul><li>Hmmm, voice activated technology still converts to ASCII… </li></ul></ul><ul><ul><li>Finding photos and video still relies on keyword search…. </li></ul></ul>
  12. 12. Will we ever get rid of Boolean? <ul><li>Probably not. Indexes are here to stay, too. The reason? Think about Desk Set and the argument that Katharine Hepburn’s character made. “They can’t replace us with a computer, there is too much cross-referencing that we do.” </li></ul><ul><li>This is still true today. </li></ul>
  13. 13. In Summary <ul><li>Metadata Golden Rule – content providers will determine the nature of metadata </li></ul><ul><li>Key to exploiting organizational power of metadata – Conceptual schema </li></ul><ul><li>Editorial librarian – Use metadata to put info into context for users </li></ul>
