This profile sets minimum expectations for a Location resource to record, search, and fetch information about a location. It is based on the [AU Base Location](http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-location.html) profile and identifies the **additional** mandatory core elements, extensions, vocabularies and value sets that **SHALL** be present in the Location 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:

* Record or update basic information for a location
* Read information about a location referenced by another resource

### Profile Specific Implementation Guidance

* See guidance on the construction of an identifier on the relevant Identifier profile page and the section on [Business Identifiers](https://build.fhir.org/ig/hl7au/au-fhir-base/generalguidance.html#business-identifiers) in AU Base.
* See the [AU Base Location](https://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-location.html) profile for guidance on using a Location resource as part of defining a type of mobile or remotely delivered service.
* When constructing an address 
* an international address can be represented using the core [Address](http://hl7.org/fhir/R4/datatypes.html#Address) data type
* an Australian address **SHOULD** be represented using the [Australian Address](http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-address.html) data type profile
 

**Usages:**

* Refer to this Profile: [AU Core Encounter](StructureDefinition-au-core-encounter.md)
* Examples for this Profile: [Tindal Building](Location-bobrester-medical-center.md), [Murrabit Public Hospital](Location-murrabit-hospital.md) and [Patient's home](Location-patient-home.md)
* CapabilityStatements using this Profile: [AU Core Requester CapabilityStatement](CapabilityStatement-au-core-requester.md) and [AU Core Responder CapabilityStatement](CapabilityStatement-au-core-responder.md)

You can also check for [usages in the FHIR IG Statistics](https://packages2.fhir.org/xig/resource/hl7.fhir.au.core|current/StructureDefinition/StructureDefinition-au-core-location.json)

**Changes since version 2.0.0:**

* The resource metadata has changed (description)

### 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.

| | | | |
| :--- | :--- | :--- | :--- |
| name | **SHALL** | `string` |  |
| address | **SHOULD** | `string` |  |
| address-city | **SHOULD** | `string` |  |
| address-state | **SHOULD** | `string` |  |
| address-postalcode | **SHOULD** | `string` |  |

#### Mandatory Search Parameters

1. **SHALL** support searching based on text name using the **[`name`](https://hl7.org/fhir/R4/location.html#search)** search parameter:`GET [base]/Location?name=[string]`Example:
1. GET [base]/Location?name=Hospital
**Implementation Notes:** Fetches a bundle of all Location resources matching the name ([how to search by string](http://hl7.org/fhir/R4/search.html#string))

#### Optional Search Parameters:

The following search parameters **SHOULD** be supported:

1. **SHOULD** support searching based on text address using the **[`address`](https://hl7.org/fhir/R4/location.html#search)** search parameter:`GET [base]/Location?address=[string]`Example:
1. GET [base]/Location?address=QLD
**Implementation Notes:** Fetches a bundle of all Location resources matching the address ([how to search by string](http://hl7.org/fhir/R4/search.html#string))
1. **SHOULD** support searching using the **[`address-city`](https://hl7.org/fhir/R4/location.html#search)** search parameter:`GET [base]/Location?address-city=[string]`Example:
1. GET [base]/Location?address-city=Westmead
**Implementation Notes:** Fetches a bundle of all Location resources matching the city ([how to search by string](http://hl7.org/fhir/R4/search.html#string))
1. **SHOULD** support searching using the **[`address-postalcode`](https://hl7.org/fhir/R4/location.html#search)** search parameter:`GET [base]/Location?address-postalcode=[string]`Example:
1. GET [base]/Location?address-postalcode=3005
**Implementation Notes:** Fetches a bundle of all Location resources matching the post code ([how to search by string](http://hl7.org/fhir/R4/search.html#string))
1. **SHOULD** support searching using the **[`address-state`](https://hl7.org/fhir/R4/location.html#search)** search parameter:`GET [base]/Location?address-state=[string]`Example:
1. GET [base]/Location?address-state=TAS
**Implementation Notes:** Fetches a bundle of all Location resources matching the state ([how to search by string](http://hl7.org/fhir/R4/search.html#string))
