Is there a reason for that? Also you use the abbreviated syntax. It might be helpful to use the un-abbreviated syntax in all examples except one section where the abbreviated syntax is explained. Your example does however show that the abbreviated syntax doesn't make anything better w.r.t. the wikidata usecase. The way wikidata models this is arguably even more horrible. It is an ordered list with marriages of Richard Burton. Each marriage is a list entry which could be a blank node, etc. Elisabeth Taylor presumably has her own list of marriages and nothing but ardent querying connects the two lists I suppose. >and that was before reading Ora's use-cases... ;) The wikidata use case has been part of the RDF* use cases for a year now, or two? Maybe it would be helpful to name this problem properly - not "wikidata usecase" but rather "multiset problem", or "multiset use case"?
