On yesterday's teleconference Claude Nanjo reviewed the FHIR ontology
approach that he developed:

.
One of the main discussion points was about how to model FHIR's
modifying extensions, which have the ability to change the semantics of
the immediately enclosing element and any elements or attributes
enclosed by that element, thus potentially leading to non-monotonic
semantics. (This is issue #1 on the group's issue list.) Lloyd
McKenzie and others discussed some possible approaches for modeling them
in RDF that would still ensure monotonic semantics.
Next week we plan to spend the first half of the teleconference
finishing the review of independent FHIR ontology approaches, with a
review of Cecil Lynch's FHIR ontology work. In the second half we plan
to discuss requirements for a converged FHIR ontology. We have started
collecting requirements ideas at
http://wiki.hl7.org/index.php?title=FHIR_Ontology_Requirements
The plan for FHIR ontology development after next week is to hold some
break-out calls for digging into individual technical details, to enable
other work to be discussed on the main teleconference. The break-out
group will summarize its progress with the main group.
