Composition (Shared Medicines List Authored by Practitioner) has bug in invariants for information-recipient

Prerequisites

• [x] I have verified the problem exists in the available content
• [x] I have searched open and closed issues to make sure it isn't already reported
• [x] I have written a descriptive issue title

The bug

Five invariants on the optional extension Composition.extension:informationRecipient have faulty FHIRPath expressions. The consequence of which is that acceptable content for this element always fails to be valid against these invariants.

The affetced invariants are:

• inv-dh-cmp-07: A practitioner shall conform to Base Practitioner
• inv-dh-cmp-08: A patient shall conform to Base Patient
• inv-dh-cmp-09: A related person shall conform to Base RelatedPerson
• inv-dh-cmp-10: A practitioner role shall conform to Base PractitionerRole
• inv-dh-cmp-11: An organisation shall conform to Base Organization

All of the above invariants share the same FHIRath expression pattern, which are variations of

all($this.reference.exists() implies resolve().where($this is Practitioner).conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/practitioner-dh-base-1'))

What I expected to happen

Acceptable content for this element shall be valid against these invariants. Unacceptable content for this element shall not be valid against these invariants.

The fix

Verification of this FHIRPath pattern with targeted examples, conclude that the FHIRPath that works is of this pattern:

all($this.valueReference.reference.resolve().where($this is Practitioner).exists() implies $this.valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/practitioner-dh-base-1'))

Workarounds

Providing a logical reference via identifier rather than a reference to a resource.

This issue is accepted as a known issue due to project constraints in accordance with the following requirements:

• this is not a mandatory element;
• there is a functioning workaround
• this content is not expected in the PSML use case

Hi @RichardTON, this issue is being re-opened given the change of default behavior of the publisher as well as the additional invariant being faulty (inv-dh-cmp-12, as documented in #59).

Asking you to review the known issue variation (see CIFMM-3278) and if OK, to re-close this issue.

thanks

Change in IG Publisher validation behvaiour from always failing instances with Composition.extension:informationRecipient to always passing.

This behavior is accepted as a known issue and documented in the SML FHIR IG via: https://github.com/AuDigitalHealth/ci-fhir-stu3/commit/2bacc4bba68eaf042fae5e3545ea6b8fffb580a0#diff-0c3a887c600181a92b738f7c87f57860

Later versions of IG Publisher have been updated and the content validation works as expected when correct FHIRPath expressions are provided. As a result, FHIRPath expressions have been updated for invariants inv-dh-cmp-07 to inv-dh-cmp-11:

• inv-dh-cmp-07: A practitioner shall conform to Base Practitioner all($this.valueReference.reference.resolve().where($this is Practitioner).exists() implies $this.valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/practitioner-dh-base-1'))
• inv-dh-cmp-08: A patient shall conform to Base Patient all($this.valueReference.reference.resolve().where($this is Patient).exists() implies $this.valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/patient-dh-base-1'))
• inv-dh-cmp-09: A related person shall conform to Base RelatedPerson all($this.valueReference.reference.resolve().where($this is RelatedPerson).exists() implies $this.valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/relatedperson-dh-base-1'))
• inv-dh-cmp-10: A practitioner role shall conform to Base PractitionerRole all($this.valueReference.reference.resolve().where($this is PractitionerRole).exists() implies $this.valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/practitionerrole-dh-base-1'))
• inv-dh-cmp-11: An organisation shall conform to Base Organization all($this.valueReference.reference.resolve().where($this is Organization).exists() implies $this.valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/organization-dh-base-1'))
