Vipul,

I was responding to Helen's request for information about  "a good  
ontology version of RIM/CDA"

I think Alan Rector's paper is still relevant to your use case. My  
understanding is that, in his view,  HL7/RIM/CDA are *information  
model* constructs that use *terminology codes*  that are induced/have  
bindings from ontology or *model of reality" things. So if you are  
modeling eligibility criteria using HL7RIM/CDA, most of the items in  
your spreadsheets are terminology codes, not entities in an ontology.

There are so many ways to model eligibility criteria.  I am not sure I  
understand "filling this table with HL7/RIM/CDA constructs." The RIM  
Acts have criterion mood. So an eligibility criterion involving "Serum  
Creatine," for example, can be an Observation Act in criterion mood  
with code = a terminology code for Serum Creatinine and value = an  
interval of Physical Quantity (and maybe effectiveTime to express  
temporal constraint. Presumably Tom Marley's OWL ITS of the HL7 RIM  
would give you such a RIM construct the criterion in OWL syntax.  
(Alternatively, you can use GELLO to write the criterion). Using OWL  
expressions to model eligibility criteria is another matter. I  
apologize if these comments reflect my ignorance about what you are  
doing.  I am not familiar with prior discussions about the spreadsheet.
