Tracking “Particular/Instance” a sufficient Ontology?
1 RTS IS NOT ADRESSING AN UNKNOWN ISSUE BY EHR EITHER EXISTING OR DEVELOPING
(Cimino,HL7,Open EHR, CEN TC 251 et.)
ex CEN Archetype
2 IT IS AN INTERESTING CONTRIBUTION TO SEMANTIC INTEROPERABILITY
3 IT IS NOT EASY TO IMPLEMENT FOR TOO MUCH BASED ON AN HOLISTIC MODEL :PUI/IUI

Tracking “Particular/Instance” a sufficient Ontology?
4 IT IS CONTRADICTORY WITH THE NECESSARY DISJUNCTION BETWEEN MODEL OF KNOWLEDGE (Ontology) and MODEL OF USE (clinical terminology:snomed ct)
5 IT ADRESSES INTERESTING SIDE POINTS
-Definition of ontology in Biomedicine
-Philosophical based oppositions
.Particular/Universal
.Assignment/Reservation
6 A VERY GOOD ANALYSIS OF NEEDS FOR SEMANTIC INTEROPERABILITY BETWEEN EHR BUT NOT THE MOST EFFICIENT (EVEN IF ELEGANT)WAY TO SOLVE THE PROBLEM IF USED ALONE

-Electronic healthcare record prEN13606Part 2 : Archetypes
CEN prEN13606 Archetype :
set of minimal terminology and context structure constraints to support the production of meaningful units of restricted knowledge(not only information but not full knowledge) to be interchanged without ambiguity
No language priority:Person statusPoint of timeTerminology /ontology usedType of event ,ordered or fixedObservation,evaluation,instruction
an archetype must be designed to constrain configurations of instances of a simple node/arc information model, that express for instance “microbiology test result” or a “physical examination”.
It is the interface between the formalisms used for generic EHR classes representation(reference architecture,data types,format )and information on PARTICULAR/INSTANCE encapsulating context and terminologies based or not on ontology.
2 IT IS AN INTERESTING CONTRIBUTION TO SEMANTIC INTEROPERABILITY
Starting from clear “philosophical” assumptions
1 Particular versus Universal
2 Assignment versus reservation
The use of PUI/IUI in EHR statements is presented with “logical” ELEGANCE:
- Text-based EHR systems
- Formally structured statements (ontology)
- Concept based systems (Snomed)

3 IT IS NOT EASY TO IMPLEMENT
Questions are listed
1 Distinction assignment reservation “can be problematic”
2 The existential uniqueness of the PUI/IUI “existence has already been determined”
3 Previous assignment ?
4 Relevance to assign different across EHRs
5 Management of PUI/IUI generator,PUI/IUI repository, RTSDB data bases
To what extent this ideal solution can be operationalized and at what cost to be practically implemented to be useful ?

4 IT IS CONTRADICTORY WITH THE NECESSARY DISJUNCTION BETWEEN MODEL OF
KNOWLEDGE (Ontology) AND MODEL OF USE (Clinical terminology :snomed ct)
“although none of these architecture take particulars into account …the modifications to be made are minor”
Text based EHR
Concept Systems
Formally structured statements(ontology)
Some curious equivalence as
ONTOLOGY/CONCEPT SYSTEMS
To what extent existing applications and tools can be improved and at what cost to come useful ?
