This section is informative and not a requirement for systems conforming to the US Core Provenance Profile.
Provenance typically communicates a single activity about one or more target resources identified via Provenance.target
. However, it can focus on one or more resource elements using the FHIR Target Element extension on Provenance.target
and identifying the target elements using element ids. For example, to document how and who supplied patient demographic data such as race, ethnicity, etc.
Example:
In the following US Core Patient Profile example, the patient demographic data such as race have individual element ids within a resource for internal and external referencing:
{
"resourceType": "Patient",
"id": "example-targeted-provenance/_history/1",
"meta": {
"versionId": "1",
"profile": [
"http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient"

The following US Core Provenance Profile resource communicates who, how, and when elements such as Race and Ethnicity (R/E), sex, etc., were collected. Note that the Target Element Extension references the element id "race" within the Patient resource:
{
"resourceType": "Provenance",
"id": "example-targeted-provenance",
"meta": {
"versionId": "1",
"profile": [
"http://hl7.org/fhir/us/core/StructureDefinition/us-core-provenance"

},
"target": [
{
"reference": "Patient/example-targeted-provenance/_history/1",
"extension": [
{
"url": "http://hl7.org/fhir/StructureDefinition/targetElement",
"valueUri": "race"
}
]
