  1. Transitions, transformations, and shifting sands:the landscape beyond MARC; the ground beneath the record Gordon Dunsire Presented to the RDA Programs Taskforce Annual Forum, ALA Annual, New Orleans, 25 June 2011

Heading: MacDonald, Mary Author: 8765 Content type: text LCSH authority record: 1234 n8765 Heading “MacDonald, Mary” ISBD Media type: microform Heading: Cataloging t1234 Preferred label “microform” b12345 Title “Cataloguing is fun!” LCSH: 1234 b12345 Author n8765 b12345 Media type t1234 b12345 Content type t9876 b12345 LCSH lc1234 t9876 Preferred label “text” lc1234 Heading “Cataloging”

  3. Shift of focus • From record to individual metadata statement • No need to copy record to add a new field • Just add a new triple to the soup • Manage the statement • Create, store, publish, preserve • Display the “record” • Aggregation of statements • Under the control of the user?

  6. From here ... • Legacy statements useful for new stuff • Authorities • Old expressions, new manifestations • Lots of duplicate legacy records • So lots of duplicate statements after conversion • De-duplicate with “same-as” links • Need appropriate representations of metadata attributes and relationships • ISBD, FRBR/AD/SAD, RDA, UNIMARC, MO/ADS, ...  • Where is MARC21?

  7. ... to there (and back again?) • Choice of types of statement • dct:title • isbd:P1004 (has title proper) • frbr:P3020 (has title of the manifestation) • rda:titleManifestation • Can re-use instead of creating new types • Can develop same-as links • Requires inter-agency, international collaboration ...
