re: this conversation about UUIDs, I believe in the past we have discussed the need for identifying both the record and the source of the record.
I think Kate talked about their approach to compound UUIDs though on the fly I can’t find it.
I did find this thread which seems relevant? https://forum.openreferral.org/t/publisher-source-metadata-at-a-record-level/625/3 ~ seems this conversation is now veering away from the subject of the current thread, we might want to redirect comments about IDs elsewhere?
