To resolve any conflicts in understanding of the SNOMED CT license for members about what content changes are permitted within extensions, the IHTSDO member countries are seeking consensus as to what types of changes are allowed.
Whilst it the IHTSDO could declare or prohibited certain extension types outright, consensus with members of the Content Managers advisory group would ensure any decisions are align with member expectations and requirements.
The original discussion paper is available here. Members are asked to provide comment on the following statements:
- Members are allowed to create new concepts.
- Members are allowed to fully define concepts they create.
- Members are allowed to state additional IS A relationships against core (international) concepts. (Specifically to newly created concepts.)
- Members are allowed to classify terminology extensions.
- Members are allowed to retire (redundant) IS A relationships (not necessarily stated).
- Members are allowed to add additional defining (non-IS A) relationships to primitive core concepts.
- Members are allowed to retire content considered "inappropriate".
- Retire concepts
- Retire relationships
- Retire descriptions
Additional descriptions and language preferences are unanimously supported. Any of the above edits, are required to be RF2 compliant, with the ability to extract an "unaltered" international release if required.
