[Mulgara-general] Hierarchical queries

[Lars Marius Garshol]

I have a foo:contains property which is transitive, and would like to do a single SPARQL query that retrieves the transitive closure along this property. I naively tried making the property an instance of owl:TransitiveProperty, but quickly found that this had no effect.

I found this

  http://docs.mulgara.org/tutorial/krule.html

but it's not clear whether Krule 

 (a) is powerful enough to express this type of rule, and

 (b) is the right way to do what I'm trying to do.

Thoughts?
