Re: Annotation Concept vs Document (was Level 1 comments)

I think we're close to straying off topic and would propose that we
take this off list :)

But ...

Ahem. Yes.

There was significant discussion about it.

The major issues were:
* DOIs are not URIs. eg There's no DOI in:
http://www.iana.org/assignments/uri-schemes.html
Note in http://www.openarchives.org/ore/1.0/datamodel.html#ore:similarTo
the URI is an info:doi/ URI

* There was a strong feeling that as a set of _web_ resources, non
resolvable URIs did not have a place in the world view.  While I agree
with the principle, the stance taken may have been too strongly
worded.
(eg in http://www.openarchives.org/ore/1.0/datamodel#Aggregated_Resource)

It was seen somewhat as the equivalent of reifying annotea's context predicate.

Eg there is some context described by the proxy in which the use of
the Source resource takes place.
And that context could include state, segment of interest, style [not
that we had it then] etc.

So it could be read as:  In the context of the annotation, I'm
referring to this segment of the resource.

handwave, mumble, cough...   :)

We could add text to the paragraph starting "When rendering a Specific
Resource,...":

If a Specific Resource has a styleClass, but no such class is
described by a CssStyle attached to the Annotation, then the
styleClass MUST be silently ignored.

Thankfully I wasn't the lead editor on either of those docs ;)  but
yes, they are intended to have a specific media type [thank you
Stian!].
