Provenance of a resource is a record that describes entities and processes involved in producing and delivering or otherwise influencing that resource. Provenance provides a critical foundation for assessing authenticity, enabling trust, and allowing reproducibility. Provenance assertions are a form of contextual metadata and can themselves become important records with their own provenance. Provenance statement indicates clinical significance in terms of confidence in authenticity, reliability, and trustworthiness, integrity, and stage in lifecycle (e.g. Document Completion - has the artifact been legally authenticated), all of which may impact security, privacy, and trust policies.
The Provenance resource tracks information about the activity that created a version of a resource, including the entities and agents involved in producing a resource. This information can be used to form assessments about its quality, reliability or trustworthiness, or to provide pointers for where to go to further investigate the origins of the resource and the information in it.
Provenance resources are a record-keeping assertion that gathers information about the context in which the information in a resource was obtained. Provenance resources are prepared by the application that initiates the create/update etc. of the resource. An AuditEvent resource contains overlapping information, but is created as events occur, to track and audit the events. AuditEvent resources are often (though not exclusively) created by the application responding to the read/query/create/update/etc. event.
Many other FHIR resources contain some elements that represent information about how the resource was obtained, and therefore they overlap with the functionality of the Provenance resource. These properties in other resources should always be used in preference to the Provenance resource, and the Provenance resource should be used where additional information is required, though overlap can occur.
The relationship between a resource and its provenance is established by a reference from the provenance resource to its target. In this way, provenance may be provided about any resource or version, including past versions. There may be multiple provenance records for a given resource or version of a resource.
The Provenance resource is based on the W3C Provenance specification , and mappings are provided. The Provenance resource is tailored to fit the FHIR use-cases for provenance more directly. In terms of W3C Provenance the FHIR Provenance resources covers "Generation" of "Entity" with respect to FHIR defined resources for creation or updating; whereas AuditEvent covers "Usage" of "Entity" and all other "Activity" as defined in W3C Provenance.
The W3C Provenance Specification has the following fundamental model:
Where:
The Provenance resource corresponds to a single activity that identifies a set of resources (target) generated by the activity. The activity also references other entities (entity) that were used and the agents (agent) that were associated with the activity. To record multiple activities that resulted in one (target), record each (activity) in independent Provenance records all pointing at that (target).
The Provenance resource depends upon having References to all the resources, entities, and agents involved in the activity. These References need not be resolvable. The references must provide a unique and ambiguous identification. If a resource, entity, or agent can have different versions that must be identified, then the Reference must have versioning information included.
Versioning and unique identification are not mandated for all systems that provide Resources, entities, and agents. But, inclusion of Provenance requirements may introduce requirements for versioning and unique identification on those systems
The Provenance resource is based on leveraging the W3C Provenance specification to represent HL7 support of provenance throughout its standards and explicitly modelled as functional capabilities in ISO/HL7 10781 EHR System Functional Model Release 2 and ISO 21089 Trusted End-to-End Information Flows. Mappings are provided. The Provenance resource is tailored to fit the FHIR use-cases for provenance more directly. In terms of W3C Provenance the FHIR Provenance resources covers "Generation" of "Entity" with respect to FHIR defined resources for creation or updating; whereas AuditEvent covers "Usage" of "Entity" and all other "Activity" as defined in W3C Provenance.

The Provenance resource identifies information about another resource (the reference element). The Provenance resource may be used in several different ways:
When used in a document bundle, the references are often not explicitly versioned, but they always implicitly pertain to the version of the resource found in the document. On a RESTful system, the target resource reference should be version specific, but this requires special care: For new resources that need to have a corresponding Provenance resource, the version-specific reference is often not knowable until after the target resource has been updated. This can create an integrity problem for the system - what if the Provenance resource cannot be created after the target resource has been updated? To avoid any such integrity problems, the target resource and the Provenance resources should be submitted as a pair using a transaction.
The Provenance resource includes a signature element (digital signature) which can be used for standards based integrity verification and non-repudiation purposes. The Signature datatype provides details on use of the signature element. The Signature.type coded value of "Source" should be used when the signature is for simply proving that the resource content is the same as it was when the resource was updated or created.
Because the Provenance resource often refers to parties that are not represented as FHIR resources, agent and entity references can be either references to other resources, or they can refer to other entities that are not FHIR resources.
For Provenance.agent, the actor element is used to reference an existing resource. To reference an entity that is not a FHIR resource, the userId element is used.
A version specific reference to a FHIR resource on the same server:
<agent> <actor> <reference value="Patient/34/_history/3"/> </actor> </agent>
A reference to a user (a person) not represented by a FHIR resource:
<agent> <userId> <value value="http://acme.com/users/34"/> </userId> </agent>
For Provenance.entity, the code in the .type element is used to differentiate between the two cases: if the code is in the system "http://hl7.org/fhir/resource-types", then the reference is to a resource, and the element reference functions exactly the same as in a resource reference.
A version specific reference to a FHIR resource on the same server:
<entity> <type> <system value="http://hl7.org/fhir/resource-types"/> <code value="Patient"/> </type> <reference value="Patient/34/_history/3"/> </entity>
In effect, this is the same pattern as a standard resource reference, but the type becomes extensible to allow referencing other kinds of resources.
A reference to an entity (a person) not represented by a FHIR resource:
<entity> <type> <system value="http://hl7.org/fhir/provenance-participant-type"/> <code value="person"/> </type> <reference value="http://acme.com/users/34"/> </entity>
One subtle issue with the use of the Provenance resource is to differentiate between whether the reference is to the resource itself, or whether the reference is to the real-world thing that the resource represents, e.g. was it the person involved in the activity, or the record of the person. For agents, it should be understood that the reference is to the real-world thing that the resource represents.
A Provenance record can be recorded to indicate who deleted a Resource. If versioning is supported, the version that was deleted is referenced in Provenance.target; if versioning is not supported then Provenance.target contains the non-version reference. Provenance.entity is not used unless there is a business requirement to do so.
Provenance can be used to record activities of an automaton that transforms input. Such as middleware that extracts information from a HL7 v2 message and creates FHIR resources, or middleware that extracts information from an HL7 CDA document and creates FHIR resources, etc. The Provenance in these cases is recording the activity of the middleware.
The middleware in this case would, in addition to creating the target resources, create a Provenance resource that indicates all the target resources (using Provenance.target). The middleware is identified as one of the Provenance.agent elements, with the Provenance.agent.role of assembler.
The middleware may record the source as another Provenance.agent element.
The original content is optionally saved. This might be as a DocumentReference, or Binary. The Provenance.entity would then point at this original content.
The original source might include some form of 'provenance' to cover the history of the original content prior to the import transformation. This original source 'provenance' should be converted into FHIR Provenance records as appropriate.
Search parameters for this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.
