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

Hi Antoine,

I am reading [4], and initially I did not like so much the name
"skos:relatedMatch". I think was too generic... I agree that major and minor
were very difficult to understand, but skos:overlappingMatch for me was
better. But now I see that we intend to cover not only overlapping Matches,
but also other kind of matches... So I think "skos:relatedMatch" its fine.

I agree with proposal 1: I would not say skos:exactMatch rdfs:subPropertyOf

Concerning "shall we allow cycles for broadMatch and narrowMatch?" I would
say no.

I agree that broadMatch and exactMatch are transitive.

At the end of the file, the sentence "PROPOSAL 2: a NEW ISSUE is raised on
mapping links between conceptual entities that are not of type skos:Concept"
means that we can map also for example classifications schemes? or

Dear all,

Sorry I realized that I has made a mistake with my different version of 
the wiki page.
The reference [4] below, for the proposal, should read

(there was still a problem with some overlappingMatch occurrences)
