Topic: Fetching references using the Validator

Hi,

I'm trying to validate an instance of a profile that uses slicing by target profile, using the HL7 Validator. However, the Validator cannot resolve the referenced instance:

Error @ Encounter.participant[0] (line 16, col17) : Slicing cannot be evaluated: Problem evaluating slicing expression for element in profile http://nictiz.nl/fhir/StructureDefinition/nl-core-Encounter path Encounter.participant[0] (fhirPath = true and individual.resolve().conformsTo('http://nictiz.nl/fhir/StructureDefinition/nl-core-HealthProfessional-PractitionerRole')): The URL 'PractitionerRole/nl-core-HealthProfessional-PractitionerRole-01' is not known to the FHIR validator, and has not been provided as part of the setup / parameters

So I'd like to provide the target instance as part of the setup / parameters, but unfortunately this section on the Confluence page is marked "TODO". I tried supplying the target as an additional instance to validate and tried to include it as an -ig, but the error persists. Could someone point me in the right direction?

how do I reproduce this?

view this post on Zulip Pieter Edelman (Oct 01 2021 at 06:46):

The command I use is java -jar /path/to/validator_cli.jar -version 4.0 -ig resources/ -recurse examples/nl-core-Encounter-01.xml

The "resources" dir (resources.zip) contains a set of conformance resources, including the profile containing the slicing logic. The "examples" dir (examples.zip) contains all examples, including the filed "nl-core-Encounter-01.xml" and "nl-core-HealthProfessional-PractitionerRole-01.xml", which both have the .id's identical to the file names.

Variants I tried:

  • java -jar /path/to/validator_cli.jar -version 4.0 -ig resources/ -recurse examples/nl-core-Encounter-01.xml examples/nl-core-HealthProfessional-PractitionerRole-01.xml
  • java -jar /path/to/validator_cli.jar -version 4.0 -ig resources/ -ig examples/ -recurse examples/nl-core-Encounter-01.xml
  • From the examples dir java -jar /path/to/validator_cli.jar -version 4.0 -ig /full/path/to/resources/ -recurse nl-core-Encounter-01.xml

I don't know if references to files on disk even work for the Validator, but they work for the IG Publisher so I kinda assumed that it would work similarly.

No, they don't. Which is why I wondered how you were doing it

it's a todo, as you saw

Ah ... I just thought the documentation was "TODO" ;)

Also running into 

-  error at Observation.hasMember[0] (38, 16):
     Slicing cannot be evaluated: Problem evaluating slicing expression for element in profile <cut>/TNMStaging path Observation.hasMember[0] (fhirPath = true and (resolve() is Observation)): The URL 'Observation/ils-test-TumorStage' is not known to the FHIR validator, and has not been provided as part of the setup / parameters

where we reference Resources on local disk/folder, adjacent to the being-validated Resource
