RESOLUTION: Minutes approved unanimously
http://wiki.hl7.org/index.php?title=FHIR_Ontology_Requirements
<scribe> ACTION: Claude to work up use case example of RDF benefit to present in San Antonio [recorded in http://www.w3.org/2015/01/06-hcls-minutes.html#action02] -- PENDING

Claude: Will show DoD federation example. Tony slides on comparing ont approaches?
http://wiki.hl7.org/index.php?title=FHIR_Ontology_Requirements
Rob: Lots of overlap between #1 and #3.
David: change #1 and #3 to split instance level from meta/ontology?
others: yes
<scribe> ACTION: David to change #1 and #3 to separate instance level from ontology level [recorded in http://www.w3.org/2015/01/13-hcls-minutes.html#action02]
<trackbot> 'David' is an ambiguous username. Please try a different identifier, such as family name or username (e.g., dderour, dhansen2, dhau2, dnewman, dshotton, dwild).
David: Comments on #2?
Marc: includes extensions?
David: Yes. Needs to be more explicit?
<scribe> ACTION: Lloyd to ensure that extensions are explicitly mentioned in #2 [recorded in http://www.w3.org/2015/01/13-hcls-minutes.html#action03]

Guoqian: Talking about FHIR instances. What does the FHIR instance include?
Paul: FHIR data would be serialized in RDF.
<Marc_Twagirumukiza> I would understand FHIR instances as an example of patient data. RDF instances as an abstract model and FHIR ontology as a vocabulary where classes and properties are defined.
Lloyd: Anything that can be a FHIR resource can be represented in RDF.
<Marc_Twagirumukiza> am I right?
Lloyd: And anything in a profile can be represented in OWL.
<Marc_Twagirumukiza> +1 Anything that can be a FHIR resource can be represented in RDF.
<Sajjad_Hussain> I think it is important not mix the two: RDF as a model vs RDF-XML as a serialization language
<Sajjad_Hussain> If I understood correctly, I think the use of RDF on FHIR instances is only using RDF-XML as a serialization language for exchange purposes
Guoqian: Suggest not using the word 'instances' when talking about FHIR.
David: need to align our terminology with existing FHIR terminology
Claude: modifying extensions wreak havoc on RDF semantics. Maybe we do a low level ont and then build one on top of that to handle modifying extensions properly
Lloyd: My expectation with #4 is
tha we would provide a base translation of FHIR instances into
RDF that would NOT be safe for reasoning, becuase of modifier
extnesions. But we'd also define a mechanism for creating
refined RDF representations that would exclude all modifiers or
unknown modifiers, and that would be safe.
... So in your "reasoning safe" ontology you would exclude
modifiers that you do not understand.
<Marc_Twagirumukiza> It would help if we have a wiki page for definitions (like a glossary) to list all definitions of list of terms. i.e what we mean by xxx term. As those definitions may not always following native meaning in our WG
<Marc_Twagirumukiza> Maybe start with FHIR glossary
Claude: suggest we do an initial RDF that is unsafe.
Tony: I think that would lead to a mess.
David: I think it's important to
design it to be monotonic
... Dig into this in San Antonio
#5. Vocabulary Bindings
(SHOULD?) The FHIR ontology must support vocabulary bindings to code, Coding and CodeableConcept - including dealing with extensible value sets and multi-code system value sets.
Rob: I think this should MUST
Lloyd: Doing it is
complicated
... Instances cannot declare vocab bindings
6. Enforce Constraints
(SHOULD?) The FHIR ontology should enforce constraints that are representable in OWL/RDF whenever possible, e.g. schema constraints, regular expressions, etc.
7. Annotation Information
(SHOULD? COULD?) In the RDFS/OWL, should expose at least minimal annotation information for display.
<Marc_Twagirumukiza> Sorry I have to leave
<Marc_Twagirumukiza> I put some comments on 9. Datatype IRIs
http://wiki.hl7.org/index.php?title=ITS_RDF_ConCall_Agenda
Tony: don't have the bandwidth to prepare
Okay, we'll drop ' Tony (on teleconference) show different ontology approaches? (NOT YET CONFIRMED) "
Claude show example of using RDF to merge and federate FHIR data?
Claude: I'll show the TAPS
example.
... I will also present work from Davide Sottara on Mayo
work.
