We at the Library of Congress, Policy and Standards Division are working on mapping/linking for the various language versions of LCSH (Library of Congress Subject Headings) - so basically the same vocabulary - same construct, same structure and basis and domain.  We decided not to try to "map" or link terminology across different thesauri, because they are so often for different domains, different structures, and especially when for different languages, the concepts are not the same - so fuzzy matching would probably be as good as it would get.  Do we really need that, when co-occurrence of terms found in bibliographic records might give even better results for users to explore?  I'd like to see us use " if you liked this term, you might try these terms in these thesauri" - not saying they are the same but pointing out that others have found them to be related.  I personally prefer that approach. The maintenance on a mapping approach seems to me to be a prohibitively expensive, long-term commitment that is not sustainable, and not necessary.  - Barbara Tillett

Dear Christine

The SKOS core is now a W3C recommendation and is a stable document that will not be changed.
That said, extension for compound (cordinated) concepts is clearly needed and could someday be put either on the W3C track, either taken in charge somehow by the librarian community.
Beyond SKOS users on this forum, I cc to Barbara Tillett at LoC, with whom I remember exchanging a few words at IFLA 2010 about it, and Lars Svensson at D-NB.
Seems to me there are coordinated concepts in the D-NB linked data publication (Lars correct me if I am wrong) but I could not figure out the ontology used.

Best

Bernard

Dear all,

In the framework of our Thesaurus Alignment project and on the behalf of the members of the Thesaurus Working Group, we would like to suggest the addition of a new "compound mapping" property in the SKOS-Core.

Examples of mapping between EUR-LEX directory Code (T1) and EuroVoc (T2)

A] Intersective Mapping

T1      04.10.40 Fisheries / Common fisheries policy / State aids
ExactMatch
T2      (common fishery policy AND state aids)

B] Cumulative Mapping

T1      03.06.53 Eggs and poultry  ExactMatch  T2 (poultry OR egg)

Best regards,
