Trying to retrieve provenance for a patient with version history

[Joel Turner]

Hi,

We are running hapi-fhir version 5.2.0 and we are experimenting with versioned provenance.

Business problem: we want to look up which agent updated a specific version of a patient. We have the patient and version e.g. "Patient/102/_history/20" - and we want to retrieve the specific provenance record for that change.

We call setDontStripVersionsFromReferencesAtPaths("Provenance.target"); to make sure the provenance targets include the version of (in this case) Patient.

example: 

"target": [

        {

             "reference": "Patient/102/_history/20"

        },

],

We then try to retrieve just that provenance record by the following url:

GET "{{fhir_url}}/Provenance?target=Patient/102/_history/20"

however, what gets returned is all of the provenance records for Patient/102.

Is this the expected behavior? Is there a different way to get the result we are hoping for?

Unfortunately this isn't currently supported. It could presumably be added, given that we now do store reference versions in the reference index table. Enhancement request ticket or PR welcomed.

Cheers,

James
