All, this happened a couple of times now on this list. Could everyone try to
quote each other's mails accurately and also read them. I wrote this [1]:

[[[
As Gregg noted in a different mail [1] (I'm on a plane, so perhaps he
already responded himself in the meantime) using rdf:subject etc. would mean
that the whole thing is an rdf:Statement:

    "Don't thing rdf:subject works, as it's domain is rdf:Statement, and I
don't think
     we want to invoke Reification, so best stick with
hydra:property/subject."
]]]

So, I never said it is bad. Neither did Gregg.

I think the problem is that RDF statements are defined to consist of three
elements: subject, predicate, and object [2]. In this case, however, we do
not have statements but in most cases just subject/property or
object/property pairs.

No one on this list ever doubted that.
