Filenaming conventions for Association and Simple Reference sets

As we’ve discussed before, we’re now in the middle of transitioning these filenames over to the latest International file naming conventions:

Hi @aatkinson,

One item that I have been confused about is all files in ../terminology/* have a filename syntax of "_Snapshot". conversely all files in the ../Refset/ folder structure contain file names without the ‘_’ (underscore) which creates files names like “AssociationSnapShot” instead of “Assocation_Snapshot”.

Is there a reason the file naming convention of “_Snapshot” is not consistent between the two folder structures in the release package?

Hi @jsnyder - so the prefix before the filetype (Full/Snapshot) is optional, and can be applied to either “sct” or “der” files in any of the folders. The pattern you’re noticing is a policy decision rather than a specification - mostly because the optional prefix is there to provide some context to the file where required, and the files in the Refset folder are often more in need of further description (as they’re additional files, often specifically for that particular package) than those in the Terminology folder, which are core files and therefore rarely require further elaboration.
Having said all that, an example of the fact that the prefix is available to all files is that the OWL files in the Terminology folder also have one (eg)

  • “sct2_sRefset_OWLExpressionSnapshot_NO1000202_20260415.txt”

So it is consistently available, it’s just an optional prefix - hope that helps?

Thanks!
