            Our conclusions:

• A multilingual subject heading system is a
  necessity
• We need an international co-ordinated
  approach
• We have to build it on existing systems
• As the costs involved are huge, we have to
  concentrate on the same solution

    Aims and milestones

   MACS aims to provide                       Feasibility study (1997/99)
multilingual subject access                   • Partners SHLs & indexing
                                              • Cooperation principles
    to library catalogues
                                              • Mapping method & results
                                    MACS


 thanks to the equivalence                     Prototype (2000/01)
 links established between                     • Independent Web appli.
                                               • Management of links
 the 3 SH Languages used
                                               • Searching using Z39.50




                TEL Milestone Conference 29 – 30 April 2002                9
         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
             TEL Milestone Conference 29 – 30 April 2002   10
• 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/



              TEL Milestone Conference 29 – 30 April 2002   11

 With Search interface using the Z39.50 protocol

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)
