RE: [SKOS] Amsterdam topic "Semantic Relation Properties"

Dear all,

Based on my experience, this is what I would say:
 
  * skos:broader is transitive? yes
  * skos:broader is intransitive? no
  * skos:broader is reflexive? no
  * skos:broader is irreflexive? yes
  * skos:broader cycles are an error? yes
 
Hope this helps.
Regards,
Margherita
