15:04:13 <Zakim> Zakim has joined #hcls
15:04:15 <trackbot> Zakim, this will be HCLS
15:04:15 <Zakim> I do not see a conference matching that name scheduled within the next hour, trackbot
15:04:16 <trackbot> Meeting: Semantic Web Health Care and Life Sciences Interest Group Teleconference
15:04:16 <trackbot> Date: 13 October 2015
15:06:19 <dbooth> Topic: ValueSets
15:07:33 <Tony> Tony has joined #HCLS
15:07:42 <dbooth> Lisa Lang joined
15:07:54 <dbooth> Lisa: Olivier Bodenreider suggested that I come.

15:11:16 <ericP> http://wiki.hl7.org/images/f/ff/ValueSet_approach.pdf
15:13:22 <dbooth> tony: No changes since Atlanta face-to-face meeting.
15:22:30 <ericP> value-set to concept, concept to syste/code
15:22:51 <dbooth> david: option 2 on line 8 is misleading.  Need to reword that.
15:23:41 <dbooth> rob: List of system/code pairs may be too large to instantiate, and it may involve post-coordinated expressions that have not been created yet.  So a ValueSet is a virtual set of system/code pairs.
15:25:18 <dbooth> tony: Looking at a ValueSet definition in FHIR starting on line 18.  Need to define the RDF equivalent.
15:26:16 <dbooth> tony: line 91 defines fhir:CodeSystemURI
15:27:25 <dbooth> ... But more useful is line 101 defines CodingBase_in_Systems that can be used in restrictions.
15:27:39 <dbooth> ... With class intersection.
15:28:11 <dbooth> ... This will eliminate a lot of anonymous classes by having a named class for this.
15:28:27 <dbooth> ... 10s of thousands, all saying the same thing.
15:30:58 <dbooth> tony: fhir:CodingBase_in_Systems helps organize.
15:37:25 <dbooth> lisa: Would it look different if what you were herding was a SNOMED hierarchy?
15:38:09 <dbooth> tony: no.
15:39:19 <dbooth> tony: There are three herding classes: CodingBase_in_Systems, CodingBase_in_Concepts and CodingBase_in_ValueSets
15:40:03 <dbooth> line 124 Concept Definition
15:46:09 <dbooth> tony: line 130, nesting maps to subclass assertions.  This maps well to SNOMED class hierarchy, for example.
15:47:01 <dbooth> rob: There discussion in FHIR about making Code system its own independent resource.
15:49:13 <dbooth> dbooth: Are all nesting hierarchies representable as subclassing?
15:49:43 <dbooth> rob: no.  Anatomy hierarchy "part of" shows up a lot.  But SNOMED has morphed that into using subclasses anyway.
15:50:03 <dbooth> eric: LOINC axes are all subclasses?
15:50:08 <dbooth> rob: no, but some are.
15:52:37 <dbooth> rob: AddressPart is not a subclass.
15:54:32 <dbooth> ACTION: Rob to look at Address / AddressPart to figure out if nesting will cause problems representing nesting as subclassing
15:54:32 <trackbot> Created ACTION-30 - Look at address / addresspart to figure out if nesting will cause problems representing nesting as subclassing [on Rob Frost - due 2015-10-20].
15:56:17 <dbooth> tony: abstract Concept will be a position in the class hierarchy
15:56:19 <dbooth> http://hl7-fhir.github.io/valueset-definitions.html#ValueSet.codeSystem.concept.abstract
15:57:55 <dbooth> tony: last one is designation
15:57:56 <dbooth> http://hl7-fhir.github.io/valueset-definitions.html#ValueSet.codeSystem.concept.designation
15:59:41 <dbooth> http://hl7-fhir.github.io/valueset.html
16:01:43 <rhausam> http://hl7.org/fhir/ValueSet/designation-use
16:04:32 <dbooth> eric: Would updating the XSLT generator help us to see how this works?
16:07:00 <dbooth> eric: May help to have this in a wiki with hyperlinks to show and try examples.
16:13:41 <dbooth> ACTION: Tony to give EricP the word doc for ValueSets, to put into the HCLS wiki
16:13:41 <trackbot> Error finding 'Tony'. You can review and register nicknames at <http://www.w3.org/2014/HCLS/track/users>.
16:16:39 <dbooth> ACTION: EricP to make wiki page from Tony's ValueSet doc
16:16:39 <trackbot> Created ACTION-31 - Make wiki page from tony's valueset doc [on Eric Prud'hommeaux - due 2015-10-20].
16:17:08 <dbooth> lisa: Others here can provide more expertise on ValueSet representation - Steve Emerick
16:18:33 <dbooth> tony: Want to get through this doc first with the group, then go through it again with Steve
