Community Consulation: Proposed changes to the RF2 Identifier File Specification

Hi all,

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 are conducting a community consultation exercise prior to making any changes. Could you please all read through the following document and either comment now, or bring your feedback to the TRAG meeting in April?

SNOMED International Proposal to change the RF2 Identifier File specification

Thanks very much!
