## Resource Profile: NL Generic Functions Localization DocumentReference Profile

Official URL: http://nuts-foundation.github.io/nl-generic-functions-ig/StructureDefinition/nl-gf-localization-documentreference | Version: 0.3.0
Draft as of 2026-02-09 | Computable Name: NlGfLocalizationDocumentReference

A DocumentReference profile for registering the availability of patient data at healthcare organizations for localization services. This profile is used to indicate that certain patient data is available at a specific organization and can be accessed for localization purposes.

Usages:

- Examples for this Profile: DocumentReference/52b792ba-11ae-42f3-bcc1-231f333f2317
- CapabilityStatements using this Profile: Localization Service
