Summary of Tue Dec 9 HL7 ITS RDF Subgroup / W3C HCLS COI call -- Review of FHIR ontology approaches (cont.)

On yesterday's teleconference Claude Nanjo reviewed the FHIR ontology 
approach that he developed:
https://docs.google.com/presentation/d/10QQaOTuLxwqdPVW4sWncSiSRNhqNrpn3RAbdmPmrihs/edit#slide=id.p4
.
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.
