RE: An argument for bridging information models and ontologies at the syntactic level

 

	OK, we disagree on this point. I'd just point out that, if you are
interested in working with HL7 RIM or BRIDG, you have a conceptual mismatch with
them.
	[VK] I do not view it as a conceptual mismatch as I can get Snomed-CT
the terminology by specifying a transformation on Snomed-CT the information
model. 
	 
	I am thinking of "information model" as a kind of information-content
entity in BFO. 
	[VK] Not an expert on BFO, so will need to look it up and get back to
you.
	 
	If your Acute MI is a subclass of Observation/Problem, then instances of
"Acute MI" class are observations of Acute MI, not instances of the disease MI.
An "observation" does not have severity, location, and so on. You lose the
ability to talk about properties of the things in the world.  An information
model refers to codes not because of implementation concern, but because
component parts of informational entity are also informational entities, IMHO.
	[VK] Would like to separate the issue of incorrect modeling from the
issue of including class analogs of terminological codes into an information
model in general.
	As far as severity, location, etc are concerned, these could be
implemented as qualifiers to the observations as proposed in the Clinical
Element Model approach by Stan Huff et. al.
	That said, the issue is not that of accuracy in modeling as I used Acute
MI as an example. was proposing an information architecture where we create a
common framework to model and perform inference on information models and
terminologies.
	 
	Cheers,
