15:15:56 <dbooth> thomas: concerns about a FHIR-specific mapping language
15:18:15 <dbooth> dbooth: Objections to giving Ken a brief time slot in Monteal?
15:19:51 <dbooth> Topic: ShEx examples
15:20:02 <dbooth> harold: i put some ShEx examples on the site
15:20:22 <dbooth> ... Some of grahame's examples do not match the spec.
15:20:38 <dbooth> ... Also need to get eric to put these into the ShEx validators

15:21:08 <Tony> Tony has joined #HCLS
15:24:47 <dbooth> dbooth: Next steps for ShEx examples?
15:25:09 <dbooth> harold: Need to work with grahame on references.

15:27:21 <dbooth> Topic: FHIR References
15:27:34 <rhausam> rhausam has joined #HCLS
15:27:39 <hsolbrig> https://github.com/w3c/hcls-fhir-rdf/blob/gh-pages/examples/AllergyIntolerance.shex
15:34:40 <dbooth> The JSON looks like this:
15:34:41 <dbooth> [[
15:34:48 <dbooth>   "patient": {
15:34:48 <dbooth>     "reference": "Patient/example"
15:34:48 <dbooth>   },
15:34:50 <dbooth> ]]
15:39:14 <dbooth> tony: In the shex, there should be one more level of reference.  A fhir:Reference has a reference property and a display property:  http://hl7-fhir.github.io/references.html
15:41:41 <hsolbrig> https://github.com/w3c/hcls-fhir-rdf/blob/gh-pages/examples/Reference.shex
15:44:47 <hsolbrig> Differences in Grahame's model -- sb. fhir:Reference.link <uri>   vs. fhir:refernce
15:45:32 <dbooth> tony: we added a fhir:Reference.link <http://....> instead of grahame's fhir:reference <http://...> to point to the referenced object.
15:48:31 <ericP> <Condition xmlns="http://hl7.org/fhir"> <patient>  <reference value="Patient/example"/>                     </patient> <asserter> <reference value="http://fhir.example/Patient/example"/> </asserter>
15:48:35 <ericP> </Condition>
15:48:50 <hsolbrig> Michael VDZ argues for leaving it on the top namespace
15:48:56 <hsolbrig> EricP: WHy do we have something different in RDF than in JSON XML
15:49:11 <dbooth> michael: Better to put it at the top level of the fhir: namespace, like grahame does it: fhir:reference .
15:49:50 <ericP> <Condition xmlns="http://hl7.org/fhir">
15:49:57 <ericP>  <patient>  <reference value="Patient/example"/>                     </patient>
15:50:03 <dbooth> eric: What if we use a relative URI?
15:50:03 <ericP>  <asserter> <reference value="http://fhir.example/Patient/example"/> </asserter>
15:50:09 <ericP> </Condition>
15:51:17 <dbooth> eric: Is a FHIR processor expected to recognize http://fhir.example/Patient/example and Patient/example as referring to the same resource?
15:52:42 <dbooth> ... Will it treat them as identical?   Will it try to serialize them the same way?
15:53:32 <mvdzel> mvdzel has joined #HCLS
15:53:35 <dbooth> ... If there is an expectation that everything is resolved against the base, then those would be serialized the same way.
15:54:17 <dbooth> dbooth: Need to be able to round-trip
15:57:35 <dbooth> dbooth: Anything in double-quotes is a literal in RDF.
15:59:37 <hsolbrig> I have to leave - I've got another meeting.  Will see you at the afternoon meeting today...
16:00:38 <dbooth> dbooth: because of the round-tripping requirement, I think we need to maintain the relative URIs
16:02:39 <dbooth> dbooth: Canonical FHIR JSON does not define a way to normalize references; therefore relative URIs need to stay relative and abs URIs need to stay abs.
16:03:44 <dbooth> ISSUE: Do we need a fhir:reference (name TBD) whose value is an RDF URI of the referent?
16:03:44 <trackbot> Created ISSUE-23 - Do we need a fhir:reference (name tbd) whose value is an rdf uri of the referent?.  Please complete additional details at <http://www.w3.org/2014/HCLS/track/issues/23/edit>.
16:05:10 <dbooth> ISSUE: Must absolute and relative references be round tripped as is?
16:05:10 <trackbot> Created ISSUE-24 - Must absolute and relative references be round tripped as is?.  Please complete additional details at <http://www.w3.org/2014/HCLS/track/issues/24/edit>.
16:05:50 <dbooth> eric: i.e., do we need to maintain the distinction between relative and absolute references?
16:06:58 <dbooth> ... when round-tripping?
16:08:06 <dbooth> ACTION: dbooth to ask Grahame and Lloyd
16:08:06 <trackbot> Created ACTION-54 - Ask grahame and lloyd [on David Booth - due 2016-05-03].
16:08:19 <dbooth> Topic: 5pm call
16:08:57 <dbooth> Who can make it?  dbooth, harold, eric, rob
16:11:05 <dbooth> Topic: Michael's presentation in Montreal
16:13:24 <dbooth> https://app.box.com/s/k7i68oyi6vg54pk8ebq8leue4e1v3j83
16:13:41 <dbooth> michael: I don't know what the @base URI should be
16:13:54 <dbooth> ... Might not have one if FHIR is being submitted
16:15:08 <dbooth> michael: Also fhir-net-api puts 'Component' in the names
16:18:05 <dbooth> dbooth: RDF does not have relative URIs, but certain RDF serializations do.  in contrast, the FHIR model and FHIR JSON and FHIR XML do have relative URIs.
16:21:17 <dbooth> michael: rdfDotNet always generates xsd: prefix instead of xs: .
16:21:31 <dbooth> dbooth: We decided to standardize on using xs:
16:27:54 <dbooth> michael: Question about bundle reference.  Should it just point to the referenced  MedicationOrder object, instead of embedding it?
16:28:32 <dbooth> dbooth: how will it impact round tripping?
16:32:51 <mvdzel> bye have to go, will add some more examples to the slides and tty in Montreal

21:24:01 <dbooth> Topic: ======== 5pm Teleconference ===========
21:24:18 <dbooth> Topic: FHIR References
21:29:04 <dbooth> # Grahame is generating:
21:29:04 <dbooth>   fhir:AllergyIntolerance.patient [
21:29:04 <dbooth>      fhir:l <http://hl7.org/fhir/Patient/example>;
21:29:04 <dbooth>      fhir:Reference.reference [ fhir:value "Patient/example" ]
21:29:05 <dbooth>   ];
21:29:05 <dbooth> 
21:29:45 <dbooth> AGREED: Change fhir:reference to fhir:link to avoid confusion.
21:30:32 <dbooth> AGREED: We prefer fhir:link (at top level of FHIR namespace) instead of fhir:Reference.link, because fhir:Reference.link misrepresents itself as a property of fhir:Reference
21:31:03 <dbooth> # Grahame should be generating:
21:31:03 <dbooth>   fhir:AllergyIntolerance.patient [
21:31:03 <dbooth>      fhir:link <http://hl7.org/fhir/Patient/example>;
21:31:03 <dbooth>      fhir:Reference.reference [ fhir:value "Patient/example" ]
21:31:04 <dbooth>   ];
21:37:29 <dbooth> Present+ David Booth, EricP, Harold Solbrig, Rob Hausam
21:45:39 <dbooth> harold: I like having a type arc on a reference, which is specific about the target type, such as fhir:PatientReference instead of a generic fhir:Reference .
22:06:06 <dbooth> AGREED: If we include a type arc on a reference (such as the object of fhir:AllergyIntolerance.patient) it should be specific to the target type, such as fhir:PatientReference instead of fhir:Reference
22:06:39 <dbooth> rrsagent, draft minutes
22:06:39 <RRSAgent> I have made the request to generate http://www.w3.org/2016/04/26-hcls-minutes.html dbooth
22:13:56 <dbooth> dbooth: Still need to decide whether the type arc  on a reference should be required, optional or not used.
