| *Official URL*:http://hl7.org.au/fhir/core/StructureDefinition/au-core-documentreference | *Version*:3.0.0-ballot1 | |
| * Standards status: *[Trial-use](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](https://build.fhir.org/ig/hl7au/au-fhir-base/generalguidance.html#maturity-levels): 1 | *Computable Name*:AUCoreDocumentReference |

This profile sets minimum expectations for a DocumentReference resource to record, search, and fetch documents associated with a patient. It is based on the [DocumentReference](https://www.hl7.org/fhir/R4/documentreference.html) resource and identifies the **additional** mandatory core elements, extensions, vocabularies and value sets that **SHALL** be present in the DocumentReference resource when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context. 

See [Comparison with other national and international IGs](comparison.md) for a comparison between AU Core profiles and profiles in other implementation guides.

### Usage Scenarios

The following are supported usage scenarios for this profile:

* Query for documents belonging to a patient
* Record or update a document belonging to a patient

### Profile Specific Implementation Guidance

No guidance defined.

**Usages:**

* Refer to this Profile: [AU Core Procedure](StructureDefinition-au-core-procedure.md)
* Examples for this Profile: [DocumentReference/aups-basicsummary-data](DocumentReference-aups-basicsummary-data.md) and [DocumentReference/aups-section-emptyreason](DocumentReference-aups-section-emptyreason.md)

### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the [AU Core CapabilityStatements](capability-statements.md) for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described [here](http://hl7.org/fhir/R4/search.html) and the syntax used to describe AU Core interactions is defined [here](general-guidance.md#readsearch-syntax).

Any search parameter defined in FHIR may be 'allowed' by the system unless explicitly marked as "**SHALL NOT**". A few items are marked as **MAY** in this implementation guide to highlight their potential relevance.
