Community Consulation: Proposed changes to the RF2 Identifier File Specification

Hello Modeling Advisory Group

As SNOMED International progresses to collaborate more closely with other organisations, the opportunity will arise to model terminology content from other code systems directly in SNOMED CT.  To highlight that this content is a true alternate expression of the same logical entity, SNOMED International would like to make use of the Identifier File ( 4.2.4 Identifier File Specification ).  This is an alternative approach to using a Map file, which may be seen to imply an equivalence in entities between two code systems, but not one and the same entity.   The Identifier File has existed in the RF2 specification for many years, but it has never been populated in the International Edition.  SNOMED International are not aware of any content generators (such as National Release Centres) who do make use of this file format.

As the structure of this file is part of the RF2 specification, we need to hold a community consultation exercise prior to making any changes.   I wonder if you'd all be able to read over the following document and comment, both as a response to the consultation and also if you have any points to make about the consultation document or the feedback form itself, then it would be good to capture any suggested improvements there before sharing this document more widely:  SNOMED International Proposal to change the RF2 Identifier File specification

Thanks All!
