It would be useful to store the JobID that created a file in an xattr on the MDT inode. This would allow tracking the source of files after the fact, and can help users with the provenance of their file data (e.g. which run the files came from, which can then be used to determine runtime parameters used, whether the run was successful or not, etc.).

It isn't clear whether this would be needed on the OST inodes as well, but I think initially the MDT inode would be enough, as this would be the only xattr visible to users. The OST xattr would only be accessible for low-level scanning tools.
