<tl> niklas: in proposal 1 just add some :e :partOf :g to "fake" a graph containement

<niklasl> yes, I could go with that too if that's where we end up

<niklasl> +1 to gregg's point about working with existing RDF 1.1 systems

<pchampin> +1, it's too early to talk about optimization :->

<niklasl> +1, more about well-formedness / integrity perhaps?

<Zakim> pchampin, you wanted to ask about compliance levels

<niklasl> +1 for a very neutral name for what is currently rdfx:nameOf

<TallTed> double chevron == `<< >>`

<TallTed> properly, "double angle brackets"

<Zakim> AndyS, you wanted to talk about renaming reification vocabulary

<Zakim> gkellogg, you wanted to ask about <<()>> in concrete syntaxes

<niklasl> A way to "control" sugar+: rdfx:triple rdfs:range [ owl:intersectionOf ( [ owl:onProperty rdf:subject ; owl:cardinality 1 ] [ owl:onProperty rdf:predicate ; owl:cardinality 1 ] [ owl:onProperty rdf:object ; owl:cardinality 1 ]) ] .

<pchampin> well-formed-ness constraint: "the object of rdf:nameOf must have exactly one rdf:subject, one rdf:predicate, one rdf:object, and no two distinct nodes in the object of rdf:nameOf can have the same subject, predicate and object"

<doerthe> thank you andy, I was really just curious

<niklasl> +1 to Gregg

<AndyS> :e1 rdf:nameOf <<( :s :p :o )>> . :e2 rdf:nameOf <<( :s :p :o )>> . matches :e1 rdf:nameOf ?Z . :e2 rdf:nameOf ?Z . -- one term in the object position, used twice.

<pchampin> + 1 AndyS

<niklasl> +1 to AndyS's example; that is what we need.

<pchampin> I stand corrected, this goes beyond the problem of leanness
