  1. An Iterative Approach to Building Sustainable Repository Services on Fedora Open Repositories 2009, May 19, 2009

  2. Outline • Organizational overview and background • Claire Stewart, Head, Digital Collections • Winterton Collection project  • Karen Miller, Monographic and Digital Projects Cataloger, Bibliographic Services • Iterative approach • Bill Parod, Repository Architect, Enterprise Systems

  3. Parallel committee/department structure

  4. Repository Implementation Group project schedule may 2008 may 2008

  5. Repository Implementation Group project schedule may 2009

  6. EAD to images to EAD+images

  7. Full cataloging for each of the 76 original collections and at the container level (album, envelope, etc.) for collections of more than one container. • Individual photographs are not (generally) cataloged fully: • Title • Note (optional) • Publisher or Creator (if available) Winterton Collection cataloging

  8. Full cataloging included • Title • Dates of coverage • Abstract • Scope and contents description • Biographical or historical note • Physical description (size of album, how many pages, photos, etc.) • Subject headings

  9. Providing cataloging at the album level means that • Many individual photographs will not be described concisely by the subject headings assigned. • Some subject headings may not apply at all to some photographs.

  10. Transcribing only the photograph titles results in such problems as these when keyword searching: • Non-English words are not translated • People referred to in captions by their initials, not names • Animals referred to by given name, not by species • Non-descriptive captions

  11. A.E.B. and his well-identified crowd

  12. "Enmei and his rhino"

  13. Repository Development Strategy Implement models and services for ingest, preservation, and access of core content. 2. Provide tools for staff to ingest and manage repository content. 3. Facilitate integration of repository materials with end-user tools and services. 4. Iterate…

  14. Draw Detailed Requirements from Project Commitments: A) OAI-ORE Annotation of OCA texts  B) Cross Collection Search Project C) Winterton Photography Collection D) Kirtas Mounting Books Project E) EAD Initiative F) Hesler Photography Collection G) Chemical Bulletin H) Fava Masks I) Curator-driven Digitization Project J) Charlotte Moorman / Prgm. African Studies Audio 

  15. Inventory Content Types 1) EAD encoded finding aids 2) TEI encoded text transcriptions 3) High resolution images 4) Virtual crops of high resolution images 5) Page imaged books 6) 3D objects 7) Aggregations: full text, fielded, and faceted search 8) Audio 9) Video

  16. Project / Content Type Matrix

  17. Services by Content Type Text Service Image Service Metadata Conversion Service Discovery Service
