Maybe "property hierarchies" refers to Property:Subproperty_of, which lets you create a hierarchy of properties. Querying for the parent property finds the subproperties, e.g. [[Ancestor of::Drew Barrymore]] also finds her dad's article with [[Father of::Drew Barrymore]] if you annotate Property:Father_of with [[Subproperty of:Ancestor of]]. That's useful, but not I think "a hierarchy of pages linked by a specific property" that you're asking for. I'm not sure what "equality" refers to, maybe querying for redirected pages. It's supposed to work, I had a hard time figuring out its circumstances. I think I made some tests for this, alas ontoworld.org is still unreachable for me -- =S |
