Hi Ian, all,

I've always been conscious that the directionality of the skos:broader and
skos:narrower properties is ambiguous if you only consider the property
name.  It is too late to make any changes to the property names now, but I
do think we should make the documentation clearer (i.e. *extremely* clear).
  
Incidentally the rdfs:label for the skos:broader property is 'has broader',
so we put the 'has' into the label but left it out of the local name.  

I thought about adding an rdfs:comment to the description of the
skos:broader and skos:narrower properties specifically to indicate the
directionality, but I've been trying to avoid phrases like 'The skos:broader
predicate implies that the object of the statement is broader than the
subject' which is fine for RDF experienced folks but a bit confusing for
others (I would get 'object' and 'subject' mixed up for a good long while :)

Al.
