Daniel,
I spoke with Mark Musen about this project at the F2F, and we
(SNOMED) would be eager to work collaboratively with NCBO on this
as a demo. I'm coming out to the Protege short course next month
(funded by SNOMED) and I'll have some material for you by then.
(a) I think is to a large extent a "just-do-it" question, and we
definitely want to "do it". The interesting part to me is the
follow-up project of showing how OWL fragments built separately in
this way can be related to a more global ontology that may not be
quite so rigorously formal; that's (b).
For me, in many ways the hardest part is (c), a standard way of
encapsulating RDF-family markup in xml-schema dependent document
formats. (I know this takes us afield from "ontologies" per se.
Personally, I'd like to see GRDDL applied to these formats, but,
we've got to be realistic that clinical medical documents today are
almost never natively html, and GRDDL is/was rather html-focused.
Also, you might argue that these formats do not assume web
connectivity so it is insufficient to merely point to an extraction
transform somewhere out on the web, when that might not be
accessible; I'm not sure whether that really matters.)
To be clear, GRRDL is not specific to XHTML and can be used for
translating XML instance data as well. One can use GRDDL for "schema
annotation" and transform all of the instance data that conforms to a
particular schema into RDF. I think the following provides some of
the relevant bits that explain this
- http://www.w3.org/TeamSubmission/grddl/#ns-bind
The current GRDDL documents don't elaborate on this 'schema
annotation' use case in as much detail as I think it deserves but I
expect this issue will be addressed in future work. An exploration of
this 'schema annotation' approach using GRDDL in a different context
is here

hmm... not sure this is enough to go on in and of itself :( but it
may be useful.
I've spoken with the OpenDocument group about an RDF embedding
standard and they're thinking about it but haven't come to any firm
proposal. I also asked Norm Walsh about it a few months ago and he
had it on his issue list for DocBook, but again I'm not yet aware
of a definitive solution. For HL7-CDA, things are hazy right now.
Daniel, I'd be interested in talking over details with you when I'm
out in Stanford.
The real challenge is modeling the semantics of HL7 and creating the
appropriate transformations. Please report back any discussions to
this list as I (along with many others it seems :) am interested in
this area.
