  1. Making sense of the hybrid super union catalogue in the information environment … Gordon Dunsire Centre for Digital Library Research

  2. … some outcomes of the COPAC/Clumps continuing interoperability project

  3. Overview • CC-interop project • Integrating SCONE with CAIRNS • Union catalogues & interoperability • Metadata confusion • Some clarification

  4. CC-interop project • Funded by JISC, May 2002 - Jun 2004 • CURL OPAC (physical u.c.); CAIRNS, M25, RIDING (distributed Z39.50 u.c., or ‘clump’) • CAIRNS and CDLR involved in Work Package B: Enhance the role of clumps (in the JISC Information Environment)

  5. Work Package B • “Looking at the intelligent selection of targets in clumps utilising collection level descriptions based on dynamic landscaping” • Using the Scottish Collections Network (SCONE) to select sub-sets (“miniclumps”) of CAIRNS catalogues

  6. Collection-level description • Metadata for a collection as a whole • E.g. collector, location, education level • Can be used to search and identify collections by useful headings (“dynamic landscaping”) • Place (physical location) • Type (archive, library, museum, etc.) • Subject …

  7. “targets in clumps” • (Z39.50) catalogues • But catalogues are collections of item-level metadata • So we can treat catalogues using cld methods • And what the catalogue describes is also a collection • Typically the total bibliographic holdings of a library

  8. “intelligent selection” • SCONE retrieval interface can be used to identify CAIRNS catalogues • Catalogues and their corresponding library collections have clds in SCONE • Library clds are related to clds for special sub-collections • E.g. rare books, manuscripts, special donations, etc.

  9. SCONE/CAIRNS • SCONE and CAIRNS interfaces developed to link CAIRNS “static clumper” to SCONE • Part-resourced by the SLIC SPEIR project • In operation • User generates list of collections in SCONE • System determines which are described by available CAIRNS catalogues • CAIRNS advanced search page displayed with relevant targets pre-selected

  10. Demonstration • http://scone.strath.ac.uk/service/index.cfm

  11. Union catalogues • CC-interop was about interoperability between two types of union catalogue • COPAC is a physical aggregated copy of CURL member catalogues • A clump is a virtual aggregation of distributed (local) member catalogues • Clump2clump (hyperclump) and clump2COPAC interactions successfully demonstrated

  12. COPAC in CAIRNS • COPAC Z39.50 target added to CAIRNS • CURL includes National Library of Scotland, University of Edinburgh … • So CAIRNS includes duplicates of several catalogues • When COPAC added to CAIRNS, corresponding clds added to SCONE • Including “COPAC collection”

  13. COPAC in SCONE • “COPAC collection” linked as parent or super-collection of each of the (Scottish) CURL library collections already in SCONE • Not all Scottish CURL members are necessarily CAIRNS targets • Collection hierarchy can be used to find ‘nearest’ catalogue • In terms of aggregation level: if the library collection has no specific catalogue, a super-collection might …

  14. NLS down • NLS Z39.50 catalogue not available due to upgrades, etc. • Temporarily switched-off in CAIRNS • When NLS collection (or sub-collection) selected in SCONE, COPAC automatically presented as the relevant CAIRNS target • Service not totally disrupted • User not confused by duplicate item-level metadata

  15. And then there was … • HaIRST catalogue • Physical aggregated copy of local metadata repositories (some without local visibility) • And the HaIRST catalogue itself is a “local” metadata repository (with visibility) which can be harvested (copied) in turn • SUNCAT • p.a.c. of local/global metadata • National Burns Collection catalogue …

  16. Metadata profusion or pollution? • Metadata duplication • Direct copies (HaIRST) • Augmented copies (COPAC, SUNCAT) • Enhanced descriptive metadata • Standardised retrieval metadata • Overlapping catalogues • Partial contents copied (SUNCAT, CASS) • Distributed catalogues • Partial contents moved (CASS?, HaIRST)

  17. Anglo/UK/Scot NUC Item-level metadata Local catalogue Z39.50 catalogue Metadata repository Physical Union cat. Distributed Union cat. A Distributed Union cat. B Harvested Union cat. A Harvested Union cat. B (Distributed) NUC

  18. Landscaping • SCONE cld methods developed for COPAC and CAIRNS are applicable to • Any aggregation of structured metadata • Any aggregation of aggregation of structured metadata • The key to simplification & clarity lies in the concept of “nearest” • Simple in mono-hierarchy of NLS/COPAC, much more complex in poly-hierarchy of NLS/COPAC/CASS/SUNCAT/CAIRNS …
