Hi all,

The properties skos:broader and skos:narrower are transitive.  This means that in an open world, it's impossible to know whether one concept is the immediate parent of another, which makes e.g. building tree representations hard.  One way around this is to define sub-properties of skos:broader/skos:narrower that are not transitive, and use these to make assertions.  

Given this requirement, I was thinking of putting a couple of properties into the SKOS Extensions Vocabulary [1] called something like 'broaderDirect' and 'narrowerDirect' ... any objections?

Cheers,

Al.
