Re: "cite" and 'author of a quote'

+1

As an aside quibble re Doug's path toward an example, and
acknowledging that it is synthetic:  (1) I see no quotation  of either
the cited wikipedia article or, within that, the given text attributed
to Vannevar Bush. (2) I doubt that the wikipedia \article/ should be
typed as a Person which is what it might come out to be, all other
things being equal.

It would be good to have  a plain text explanation, devoid of
serialization examples, of who is annotating what resource, what part
the annotator is annotating, and whether they mean to be saying
something about the resource or something about the content of the
resource along with what they are trying to say.  Then let the
serialization begin!

The targeted audiences (web developers) not withstanding, the one
thing that is immutable is that something is not an OA Annotation if
it is not a graph. Most (?) of the effort of the OA CG has gone into
RDF representations, so CG many CG participants could probably more
meaningfully comment when confronted with an RDF serialization,
leaving others to argue about the accuracy of HTML representations and
the semantic agreement between them. Thus my +1 is really +0.9, since
what I see emerging is more like working iteratively from both sides
toward a use case for HTML serialization.
