SNOMED CT International Edition DEMONSTRATION release available

Dear Members,
The September 2018 DEMONSTRATION release of the SNOMED CT® International Edition is now available to SNOMED International Members.

This DEMONSTRATION release provides Members with the opportunity to have an early view of the proposed OWL file changes, in order to help our community to evaluate their tooling, systems and release processes. The new OWL Axiom reference set represents all stated relationships and all new description logic features, such as general concept inclusion (GCI) axioms and additional axioms. Please note that the content modeling is still a work-in-progress and these examples are being provided for demonstration purposes only and are not necessarily reflective of content that will be in the January 2019 or July 2019 Releases. The complete OWL axiom refset will be available on request in the January 2019 release. The complete OWL axiom refset will be mandatory from the July 2019 release onwards.

The DEMONSTRATION release package is distributed for evaluation purposes only.
It must not be used in production clinical systems or in clinical settings, or distributed to Affiliate Licensees or any third parties at this time.

All files distributed to SNOMED International Members for the September 2018 DEMONSTRATION Release are available in Release Format 2 (RF2) only.

The SNOMED CT International Edition Release Notes can also be accessed online:
