### HL7 Austria

HL7® Austria is an official Affiliate of HL7® International. Within HL7® Austria the technical committee for FHIR® (TC FHIR®) is responsible to promote and disseminate the new upcoming standard HL7® FHIR®. The TC FHIR® deals with the standard-compliant and coordinated usage of HL7® FHIR® based communication solutions. It coordinates and describes necessary localizations and offers concrete help for FHIR®-compliant interfaces.

### Relation to the Austrian EHR System (ELGA)

Currently, the Austrian EHR system (ELGA) is mainly based on HL7® CDA®. In order to enable the creation of FHIR® resources that have a similar data structure this Implementation Guide provides mappings to the CDA® based implementation guides (e.g. [Mappings for Allgemeiner Implementierungsleitfaden v3](StructureDefinition-at-core-patient-mappings.md#mappings-for-allgemeiner-implementierungsleitfaden-v3-https-wiki)). Furthermore ELGA is using the HL7® Austria FHIR® Core IG as a basis for their FHIR® Implementation Guides.
