Aims and milestones Feasibility study (1997/99) MACS aims to provide • Partners ’ SHLs & indexing • Cooperation principles • Mapping method & results multilingual subject access to library catalogues MACS thanks to the equivalence links established between the 3 SH Languages used ELAG 2002 Prototype (2000/01) • Independent Web appl. • Management of links • Searching using Z 39. 50 19 -04 -2002
Basic principles • Equality of languages and SHLs (no pivot) with autonomy of each SHL (only local, MACS is an external link database) • Establishment of equivalences (no translation) between the SHLs involved (no new thesaurus) • Equivalence links conceived as concept clusters MACS = mappings and numeric identifiers • Consistency of results (goal = users retrieval) • Extensible to other SHLs ELAG 2002 19 -04 -2002
• MACS Prototype developed by Index Data aps (Denmark) and Tilburg University/ Infolab (Netherlands) • Public access to the prototype at: http: //infolab. kub. nl/prj/macs/ ELAG 2002 19 -04 -2002
Simultaneous subject search for users in the language of their choice in preferred target catalogues ELAG 2002 19 -04 -2002

MACS Links: organizational model LCSH RAMEAU SWD BL Bn. F DDB + SNL Annotations Federative management: each SHL is autonomous, partly responsible in link-establishment, but with a full capacity of proposal, and right to check and make annotations to other SHLs ELAG 2002 19 -04 -2002

Organisational principles • Partners share equal responsibility for link authorisation: no central editor • Each partner is responsible for validating links proposed to their own SHL • Partners may make proposals concerning any other parts of the link (but must be confirmed by the responsible partner) • All partners may comment links (annotations) ELAG 2002 19 -04 -2002
