Topic: Questionnaire definition mapping to logical model

Elliot Silver (Dec 09 2020 at 20:29):

I previously raised this in the #questionnaire stream Questionnaire definition mapping to logical model but never got to the bottom of the issue, so hoping someone here might have some insight.

I have a logical model that includes an element of type Period:
(extract from the fsh source)

* differential.element[44].id = "WhoCrSurveillanceDataDictionary.exposure.travel.location.locationPeriod"
* differential.element[44].path = "WhoCrSurveillanceDataDictionary.exposure.travel.location.locationPeriod"
* differential.element[44].short = "Dates at location (including date of departure)"
* differential.element[44].definition = "Specify dates at this location"
* differential.element[44].type.code = #Period
* differential.element[44].code = $LNC#91560-3
* differential.element[44].min = 0
* differential.element[44].max = "1"

I have a questionnaire that references a sub-element of Period:

* item[6].item[1].item[0].item[2].linkId  = "expo_travel_date"
* item[6].item[1].item[0].item[2].text    = "Date of Departure from the place:"
* item[6].item[1].item[0].item[2].type    = #dateTime
* item[6].item[1].item[0].item[2].code    = $LNC#91560-3
* item[6].item[1].item[0].item[2].definition    = "http://openhie.github.io/covid-19/StructureDefinition/WhoCrSurveillanceDataDictionary#WhoCrSurveillanceDataDictionary.exposure.travel.location.locationPeriod.end"

When I build my IG, I get an error in QA.html:

The link 'StructureDefinition-WhoCrSurveillanceDataDictionary.html#WhoCrSurveillanceDataDictionary.exposure.travel.location.locationPeriod.end' for "WhoCrSurveillanceDataDictionary.exposure.travel.location.locationPeriod.end" cannot be resolved (valid targets: 233 targets)

Is there an error here on my part? I believe previous discussion suggested that I should be able to define a link into a datatype, but maybe not?

Further research on this reveals I can do a Questionnaire definition that goes into a complex data type in a resource (e.g. Practitioner.name.text), but my attempts to do a definition that goes into the profile of the same resource, or a logical model with the same structure fail.

I'll look at this next week too

Elliot Silver (Dec 11 2020 at 00:57):

Thank you.

I have a single fsh file that shows it if you need.

Michaela Ziegler (May 25 2021 at 15:47):

I become Build errors, where I set a Questionnaire.definition to a specific slice of an element (see QA). How should that work properly?

definition = "http://fhir.ch/ig/ch-rad-order/StructureDefinition/ch-rad-order-servicerequest#ServiceRequest.identifier:placerOrderIdentifier.value"

The link 'StructureDefinition-ch-rad-order-servicerequest.html#ServiceRequest.identifier:placerOrderIdentifier.value' for "ServiceRequest.identifier:placerOrderIdentifier.value" cannot be resolved (valid targets: 308 targets)

moving this back up my todo list.

Grahame Grieve (Jun 03 2021 at 00:58):

how do I reproduce this @Elliot Silver

Elliot Silver (Jun 03 2021 at 02:26):

If I recall, you need to:

create a logical model with an element of type Period
create a questionnaire with an item whose definition links to the logical model's Period.end.
I'm not sure how to point you at an old github commit that would demonstrate this.
