Hi Alistair,

About the two aspects below:
>
> Minimum consensus: Using SKOS, it should be possible to state broader, narrower, related and exact (equivalent) semantic links between concepts from different concept schemes. 
> [...]
>
> (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?

Again (I guess you got it right, but I want to clarify your "minimum 
consensus" sentence, which I fear will be over-interpreted)
the outcome of previous discussion when I released the first proposal 
for mapping vocabulary [1] was that there should be different properties 
for mapping links, because there is an essential distinction between the 
mapping links and the standard semantic relations.
This distinction is mainly about confidence and authority status: 
standard relations are the result of careful vocabulary building, while 
mapping links are much less strong. Just because it is likely that the 
context and use of the mapped concepts are different! The whole thread 
encompassing [1,2,3] discusses this.

And, again, when I say that it is necessary to allow for skos:broader 
between scheme, it is not for mapping purposes, but for extension 
purposes. Cf [2], Doug about these inter-thesaurus skos:broader. So 
there is still a need for a specific vocabulary for mapping.

Cheers,

Antoine
