4 ELAG 200219-04-2002 Aims and milestones MACS aims to provide multilingual subject access to library catalogues MACS aims to provide multilingual subject access to library catalogues Prototype (2000/01) Independent Web appl. Management of links Searching using Z39.50 Prototype (2000/01) Independent Web appl. Management of links Searching using Z39.50 Feasibility study (1997/99) Partners ’ SHLs & indexing Cooperation principles Mapping method & results Feasibility study (1997/99) Partners ’ SHLs & indexing Cooperation principles Mapping method & results thanks to the equivalence links established between the 3 SH Languages used thanks to the equivalence links established between the 3 SH Languages used MACS

5 ELAG 200219-04-2002 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

6 ELAG 200219-04-2002 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/

7 ELAG 200219-04-2002 Simultaneous subject search for users in the language of their choice in preferred target catalogues

8 ELAG 200219-04-2002 With Search interface using the Z39.50 protocol using equivalence links between subject headings

12 ELAG 200219-04-2002 Links established and maintained in the Link management interface, with mechanism for managing partial or complex links Search by SHL Click to view and edit

13 ELAG 200219-04-2002 MACS Links: organizational model 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 BnF R AMEAU Annotations BL LCSH DDB + SNL SWD

14 ELAG 200219-04-2002 SWD 041124707 AIDS RAMEAU or frBN002114472 Sida

15 ELAG 200219-04-2002 LCSH or sh85002541 AIDS (Disease)

16 ELAG 200219-04-2002 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)
