<vipul> EricP, LeeF: how do I make the logs open to the public?

<LeeF> vipul: less verbose :)

<vipul> Thanks Lee

<vipul> :)

<vipul> Do you know the commands for entering the agenda items?

<alanr> not me

<vipul> http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability?action=AttachFile&do=get&target=POMRGalenRDFPatient1.ppt

Vipul: during the last call I posted some slides. are there any comments?

Alan: had a question on slide 4: what is P1?

<alanr> http://esw.w3.org/topic/HCLS/OntologyTaskForce/POMR?action=AttachFile&do=get&target=POMR-slides.html

<alanr> http://purl.org/cpr/1.0/problem-oriented-medical-record.owl

Vipul: we will work on representing temporal constraints of the data. Parsa from Texas suggested that we can probably leverage OWL-time
... to look at the GALEN encounter model as well, and will be informing the group as progess is being made

<vipul> http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability?action=AttachFile&do=get&target=HL7MockPatientData.ppt

Helen: discussed the representing parts of HL7 in OWL
... HL7 is based on the over-arching RIM model. A class hierarchy is constructed according to the ACT type code definition.
... looked at all the codes (originally represented in OO approach), and modeled them as OWL classes

Alan: are the ACT classes modeled as RDF:List?

Helen: they are modeled as OWL sub-classes in a hierarchy
... HL7 also has the vocabulary and code and they were also modeled as OWL classes (Slide 6
... HL7 also has "own" datatype which is different than XSD or RDF datatypes

Vipul: can we use XML schema to represent the datatypes?

Helen: perhaps not
... HL7 has clinical document arch. (CDA) for recording clinical events. These events are typically sent as HL7 messages in a hospital setting.

<alanr> example CDA -> http://www.biomedcentral.com/content/download/xml/1472-6947-7-14.xml

Helen: A comparison between XSD schema elements and OWL constructs as made
... some can be modeled, but not all XSD constructs
... does OWL have the notion of "optional" similar to XML Schema?

Alan: OWL is missing the mandatory idea. OWL just talks about what "exists", not what should be known

Helen: OWL has everything has "optional", but only "mandatory" stuff

Alan: OWL does not make the distinction between "optional" and "mandatory"

Helen: explained slides 10, 11, 12, and 13 which contained mock up patient data described using elements from the HL7 RIM

Alan: how do we distinguish between "past" and "present" medical condition of the patient?

Helen: there is a way of saying "effective time" and "activity time" which can be used for making the distinction

Alan: what is moodCode="EVN"?

Helen: "EVN" corresponds to an event, it includes things such as "order", "request", "refferal" etc. These are more process oriented stuff

<alanr> http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1380194

<alanr> "HL7 Clinical Document Architecture, Release 2"

<alanr> “EVN” (event), meaning that the Act is describing something that occurred; “DEF” (definition), meaning that the Act is providing a master file type of description; “INT” (intent), where the Act is describing an action plan or order; “GOL” (goal), for describing a desired outcome; “EVN.CRT” (event criterion), which represents an event that must apply for an associated...

<alanr> ...service to be considered.

Helen: will also consider more details on interval reasoning rules

Vipu to Alan: did you talk with Dan Russler?

Alan: spoke briefly with Dan and found out that HL7 is a "model of reality"
... HL7 is trying to be an ontology, but not a file format?

Helen: data entry is also considered as "ACT" too

Alan: suggested Helen that we should take all the entries and put them in correct places.

Helen: HL7 actually never meant to be an ontology. It is more of a coding system and modeling in an old-fashioned way

Vipul: Agrees with Alan that we should view HL7 as a source of content. Also, we need to distinguish between "observations" and "acts"

<alanr> http://lists.w3.org/Archives/Public/public-semweb-lifesci/2006Aug/0131.html

Vipul: proposed that Alan, Holger et al. take a look at how they would model the patient data in OWL
