SNOMED CT Authoring Tools support the creation and modelling of new SNOMED CT concepts in accordance with the SNOMED CT Editorial Guidelines and the SNOMED CT Concept Model.

The Authoring platforms support the creation of new SNOMED CT concepts, with concept definitions that follow the specifications of the Concept Model. SNOMED CT was designed to be an extensible terminology, where extensions can create additional content to satisfy local requirements. The availability of a Concept Model specification ensures that the content created by users continues to be logically compatible, and equivalence and subsumption operations could be performed between content coming from different sources.

Typically member countries publish national extensions that include concepts necessary to support local use cases, like national programs, but it's also possible to maintain new concepts in an organizational extension, satisfying use cases directly related to the implementation of SNOMED CT. Content authored in an extension of SNOMED CT can be released as RF2 files packages, to be shared with a community of users, or it can be used to deploy to a terminology service for direct implementation use.

SNOMED CT International Authoring Platform

This tool provides the content authoring functions used to maintain the International Edition and several national extensions.

The tool supports the collaborative work of authors editing and reviewing new concepts, and updating existing concepts. The creation of concept definitions is supported by an implementation of the Machine Readable Concept Model and the use of Templates. The authoring activities are task-based, including a review process, promotion, and rebasing with dependencies updates.

The authoring tool backend is Snowstorm, the open-source terminology server maintained by SNOMED International, which can also be used as a read-only terminology server to support implementations.

The source-code for the Authoring Platform is available at: https://github.com/IHTSDO/authoring-ui
