Published 25 October 2019

The National Clinical Terminology Service (NCTS) is pleased to announce that the September combined release of SNOMED CT® AU1 and the Australian Medicines Terminology (AMT) is now available to registered users from the NCTS website.

To access the Release Note and download the RF2 files, select SNOMED CT-AU > Release Bundles from the ACCESS tab.

The reference sets are available in TSV format (containing pre-computed values for concept IDs, Fully Specified Name, Preferred Term and Synonym description only) and as HL7™FHIR® standard2 value sets (which may also be obtained via the integration interface of the National Terminology Server. To download the reference sets, select SNOMED CT-AU > Reference Sets from the ACCESS tab.

Important Information

Description Logic Changes To enable improvements to the quality and analytics capabilities of SNOMED CT, SNOMED International have enhanced the underlining logic profile of the terminology. The changes require expressing the concept definitions using Web Ontology Language (OWL). These expressions are published as an RF2 compliant reference set, replacing the stated relationships file. The (distributed normal form) relationships file included within SNOMED CT-AU, which most users use, remains unchanged. The stated relationships file was deprecated in the July 2019 International release and these changes were incorporated into this release.

Further details of the changes are available here:
