  • 1. RBMS Preconference “Futures”, San Diego, 21 June 2012Cataloging & Linked DataFrom Strings toThingsMichael PanzerAssistant Editor, DDCOCLC@MichaelPanzer The world’s libraries. Connected.
  • 2. Topics for today• Cataloging from a linked data perspective • Describing vs. identifying • Mapping vs. linking• Interlude: Technical basis for linked data• Library Linked Data: 2 Examples • Dewey.info • WorldCat.org + schema.org• Why should librarians care? The world’s libraries. Connected.
  • 3. Define “metadata”Implications for descriptivecataloging “Metadata is data associated with objects which relieves their potential- produces surrogates users of having to have full advance knowledge of their existence or- transforms textual characteristics.” information Dempsey/Heery (1997) The world’s libraries. Connected.

  • 17. Strings as keysIdentification by description• Heading construction based on elimination of ambiguities • Parts are added to increase specificity of description to avoid conflicts with other headings• Use of abbreviations, punctuation, special delimiters• Form of heading carries meaning (dates, etc.)• Headings relate to other headings• Keys act as access points for records, not described entities ≈ cutting a key based on a vague description of a lock that may not even exist The world’s libraries. Connected.
