Re: [SKOS] A revised proposal for ISSUE-39 ConceptualMappingLinks

Dear all,

Regarding

I would propose for next telecon that the workgroup accepts [4] as a 
solution to ISSUE-39 ConceptualMappingLinks [3].
This proposal is introduced in the mail attached below (also accessible 
at [6])

With respect to the 3 sub-topics raised by Alistair [7], the proposals 
made in the wiki page [4] are:

> (ISSUE-39A) Should "grouping" constructs for mapping be included, and if so, what are their semantics?
-> This sub-issue is postponed until until a solution has been found to 
ISSUE-40 ConceptCoordination [8] and ISSUE-45 
NaryLinksBetweenDescriptorsAndNonDescriptors [9], which are about very 
similar problems.

> (ISSUE-39B) Is it necessary to have parallel vocabulary (skos:broader // skos:broadMatch etc.)? If not, how do you differentiate between intra-scheme vs. inter-scheme semantic links?
-> This sub-issue is dealt with: the SKOS mapping relations are 
introduced as parallel to the existing SKOS semantic relations 
(skos:broader, etc)

> (ISSUE-39C) What's the difference between "related" and "overlapping"? Is there enough precedent to justify a new property for "overlapping"?
-> This sub-issue is dealt with: only skos:relatedMatch is kept in the 
proposal, and a discussion item gives motivation for it.


Of course I invite the WG to consider this proposal considering any new 
argument that could have been raised on the SWD and SKOS lists between 
now and next week. The current proposal tries to take into account all 
the feedback we got on the subject over the past months, but the topic 
was very active over the past days (over 20 mails in two weeks!).

Cheers,

Antoine
