Hi Alistair

This is a good framework for questions I was about to post, which fit at 
least in part in  [ISSUE-44]
What are the relation of broader/narrower semantics with conceptScheme 
semantics, if any?
    * Should broader/narrower link concepts of the same concept scheme, 
or are they allowed across concept schemes?
    * If a concept belongs to several concept schemes, would it be 
possible / does it make sense to distinguish broader-narrower 
hierarchies in different schemes?
Related question, I would like to see specified the semantics of 
ConceptScheme, and the difference between ConceptScheme and subclass of 
Concept. Maybe another issue number for this?

> Hi all,
> I'd like to suggest we focus some attention on several issues to do with the central stuff in SKOS, like the skos:Concept class, the SKOS labelling properties and the SKOS semantic relation properties. 
> This would help us to fill out some of the earlier parts of the SKOS Semantics wiki draft [1]. The wiki draft has only one section so far, on grouping constructs, and so looks a bit empty :) This would also help the discussion of other issues, such as the relationships between labels.
> There are three central issues in the tracker we could look at:
>  * [ISSUE-31] "BasicLexicalLabelSemantics" - defining the semantics of the three basic labelling properties, skos:prefLabel, skos:altLabel and skos:hiddenLabel
>  * [ISSUE-44] "BroaderNarrowerSemantics" - defining the semantics of skos:broader and skos:narrower
>  * [ISSUE-54] "ConceptSemantics" - defining the semantics of skos:Concept 
> Issue 31 is already open. Issues 44 and 54 need to be opened (I just raised 54).
> Of course we should also continue the very valuable discussion of other issues and work to our requirements document!
