APPROVED: June 30 minutes
Paul: no news yet
Tony: worked on CodeableThingy last week. Lloyd sent def. Seems ok. It's in today's version 6 side-by-side
FHIR RDF and Validation/Translation Task Force

david: Reminder: Need to get FHIR ontology and RDF examples checked into github
Rob: Should present this work at
the Expo. Want to make a submission.
... Mtg is in Uruguay in October.
... Submissions due Friday
tony: joint paper submission?
<scribe> ACTION: Rob to start drafting submission, and distribute for comment [recorded in http://www.w3.org/2015/07/14-hcls-minutes.html#action01]
<trackbot> Created ACTION-27 - Start drafting submission, and distribute for comment [on Rob Frost - due 2015-07-21].

rob: final papers due oct 12

tony: changed primitive
datatypes, including CodeableThingy
... Added index primitive also
FHIR lines 23-27 are reflected in RDF in lines 90-94
tony: fhir:CodeableThingy is
equiv to CodeableConcept
... fhir:code becomes a CodeableThingy
rob: what's the relationship between CodeableThingy and the other three?
tony: line 99
david: Purpose is to use the same RDF structure for the three different ways of indicating codes in FHIR.
paul: How do you distinguish them when going back to XML? look for the absence of property?
david: dangerous to rely on the absence of certain properties to conclude which kind it was originally.
paul: could use breadcrumb
david: agree
... Could tag it with an additional RDF class to indicate where
it originally came from.
<scribe> ACTION: Tony to ask lloyd about attaching a class breadcrumb to a CodeableThingy instance to indicate what FHIR form it was originally [recorded in http://www.w3.org/2015/07/14-hcls-minutes.html#action02]
<trackbot> Error finding 'Tony'. You can review and register nicknames at <http://www.w3.org/2014/HCLS/track/users>.
david: This makes querying more consistent -- all three use the same RDF structure -- but makes the RDF less concise. comments?
tony: the coding system could be added in.
david: Depends on what information is guaranteed to be available during FHIR XML to RDF conversion
tony: You would need to look at the structure definition.
david: If the structure definition is a part of the FHIR standard, then it can be used. If it might be defined by some other organization, then the conversion cannot count on it being available.
rob: I believe the coding system can only be fixed in structure definitions that are a part of the FHIR standard.
david: Can we confirm that?
<scribe> ACTION: Rob to check with Lloyd about whether someone can define a Code, specifying a new coding system URI in [recorded in http://www.w3.org/2015/07/14-hcls-minutes.html#action03]
<trackbot> Created ACTION-28 - Check with lloyd about whether someone can define a code, specifying a new coding system uri in [on Rob Frost - due 2015-07-21].
tony: fhir:index is defined on
line 678 and following lines
... fhir:index-primitive is the datatype for the range of
fhir:index
... That's the same way that the other FHIR datatypes are
defined.
<rhausam> code should only be used when the following conditions are met: The data element forms an essential part of interpreting the meaning of the resource, such that safe processing would be impossible without it. I.e. the element must be “mustUnderstand” or the element is a part of the FHIR infrastructure and has no clinical or business meaning The element will be bound to a code list that is complete (non-extensible) and required (everyone must use it) The [CUT]
