RE: [COI] Clinical Observations Interoperability Telcon January 15 2008

Having an integratdc specification of data types, information model, and
vocabularies based on use cases, I think, is what HL7 RIM is about.  More than a
year ago, I asked for and got a version of Tom Marley's OWL HL7 ITS. It covers
data types, RIM classes, and HL7 vocabularies. I think it's consistent with
Alan's work on terminology binding. (Tom Marley is a co-author of the Rector
paper I referenced.)
 
[VK] That may be so, but given that it is so difficult and confusing to use. May
be Semantic Web specifications can help here?
Just to let you know that we have started an effort to create an RDF
Representation of sample patient data based on classes/properties/vocabularies
based on HL7/RIM/CDA.
 
The sample patient data is available at:
http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability/MockedUpPatien
tData
 
We are also looking at the SDTM, Detailed Clinical Models and the "Realist"
approach for creating the RDF representations.
Some slides taht illustrate our thoughs are available at:
http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability?action=AttachF
ile&do=get&target=PatientDataRDF.ppt
 
Look forward to your feedback and involvement.

			Yes, I was thinking about the temporal dimensions when I
said that I don't see RDF/OWL as having particular advantages. There have been a
lot of work on temporal databases in the database community. OWL/SWRL's
open-world semantics is also a problem. The availability of classification
reasoners, however, allow you to have complex descriptions of patient
states.That's an advantage.
			[VK] Agree with you that this the ability to specify and
classify complex patient state descriptions is a key advantage.
