Delta file types in the Release File Spec

Question: Do we need to update the release file specification to reflect the new practice of not including the delta release file type in the International Edition release package?

  • As we know, the delta format is still “valid”, but it is no longer provided as part of the International release package.

  • Also we now provide a tool to generate delta files.

  • We’ve updated the Delta file specifications (3.2 Release Types) to specifically mention the removal of Delta files from the International Edition:

    • Please note :

      • Delta files have been removed from the SNOMED International release package, but a Delta Generation Tool is available for those who need it. The Delta Generation Tool allows users to create their own Delta between two fixed release dates - you can find it here: https://github.com/IHTSDO/delta-generator-tool/releases.
    • BUT this doesn’t include ALL Extensions + Derivative products - does it need to??

    • It also states at the top that :

  • ALSO the RELEASE PACKAGE CONTENTS page is definitely out of date:

    • 3.4 Release Package Contents

    • UNLESS we consider this to still be useful info for historical packages that still contain DELTA files? (or other extensions outside of SI control that still include them??)

  • If we need to do this, let’s walk through it in the Release File Spec docs…

  • Andrew Atkinson to implement changes in the Documentation:

    • ***ACTIONED - See page "***Release Types" in the new Gitbooks version of the Release File Spec

    • TRAG to confirm if this is adequate to inform users??
