6.9 Resource DocumentReference - Content

Structured Documents Work GroupMaturity Level: 2Compartments: Device, Patient, Practitioner, RelatedPerson

A reference to a document .

6.9.1 Scope and Usage

A DocumentReference resource is used to describe a document that is made available to a healthcare system. A document is some sequence of bytes that is identifiable, establishes its own context (e.g., what subject, author, etc. can be displayed to the user), and has defined update management. The DocumentReference resource can be used with any document format that has a recognized mime type and that conforms to this definition.

Typically, DocumentReference resources are used in document indexing systems, such as IHE XDS (see the XDS specific profile), and are used to refer to:

  • CDA documents in FHIR systems
  • FHIR documents stored elsewhere (i.e. registry/repository following the XDS model)
  • PDF documents , and even digital records of faxes where sufficient information is available
  • Other kinds of documents, such as records of prescriptions

6.9.2 Boundaries and Relationships

FHIR defines both a document format and this document reference. FHIR documents are for documents that are authored and assembled in FHIR. This resource is mainly intended for general references to other documents.

The document that is a target of the reference can be a reference to a FHIR document served by another server, or the target can be stored in the special FHIR Binary Resource, or the target can be stored on some other server system. The document reference is also able to address documents that are retrieved by a service call such as an XDS.b RetrieveDocumentSet, or a DICOM exchange, or an HL7 v2 message query - though the way each of these service calls works must be specified in some external standard or other documentation.

A DocumentReference describes some other document. This means that there are two sets of provenance information relevant here: the provenance of the document, and the provenance of the document reference. Sometimes, the provenance information is closely related, as when the document producer also produces the document reference, but in other workflows, the document reference is generated later by other actors. In the DocumentReference resource, the meta content refers to the provenance of the reference itself, while the content described below concerns the document it references. Like all resources, there is overlap between the information in the resource directly, and in the general Provenance resource. This is discussed as part of the description of the Provenance resource.

6.9.4 Implementation Notes

  • The use of the .docStatus codes is discussed in the Composition description
  • The resources maintain one way relationships that point backwards - e.g., the document that replaces one document points towards the document that it replaced. The reverse relationships can be followed by using indexes built from the resources. Typically, this is done using the search parameters described below. Given that documents may have other documents that replace or append them, clients should always check these relationships when accessing documents

6.9.4.1 Generating a Document Reference

A client can ask a server to generate a document reference from a document. The server reads the existing document and generates a matching DocumentReference resource, or returns one it has previously generated. Servers may be able to return or generate document references for the following types of content:

Type Comments
FHIR Documents The uri refers to an existing Document
CDA Document The uri is a reference to a Binary end-point that returns either a CDA document, or some kind of CDA Package that the server knows how to process (e.g., an IHE .zip)
Other The server can be asked to generate a document reference for other kinds of documents. For some of these documents (e.g., PDF documents) a server could only provide a document reference if it already existed or the server had special knowledge of the document.

The server either returns a search result containing a single document reference, or it returns an error. If the URI refers to another server, it is at the discretion of the server whether to retrieve it or return an error.

The operation is initiated by a named query, using _query=generate on the /DocumentReference end-point:

  GET [service-url]/DocumentReference/?_query=generate&uri=:url&...

The "uri" parameter is a relative or absolute reference to one of the document types described above. Other parameters may be supplied:

Name Meaning
persist Whether to store the document at the document end-point (/Document) or not, once it is generated. Value = true or false (default is for the server to decide).

6.9.5 Search Parameters

Search parameters for this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.
