Hi,

in preparation for the upcoming EU connectathon, I have just been trying out some of the NIST FHIR Toolkit's (version 4.3.0) test cases against our MHD Document Recipient/Responder. While doing that, I have noticed that one of the test suites (MHDv420_DocumentRecipient_minimal) reuses the same submissionset entryUUID (specifically, urn:uuid:1e404af0-0770-4be0-b7a0-a9be97e10000) for multiple test cases (1 Prerequisite Single Document with Binary, DocumentAddendum, DocumentReplace and DocumentTransforms).

However, according to my understanding of UUIDs, they should be unique (for instance, in the XDS world, they would be used to reference objects) - am I mistaken in my impression that this suggests a regeneration of these UUIDs for each ITI-65 request taken by the toolkit?

Regards, Andreas

You are correct. The NIST test tools, for MHD testing, are out-of-date as well, so are not used at connectathon. Use the connectathon mailing list to get proper instructions on how to pre-test.

Thanks! I just forwarded the pre-connectathon testing aspect of my issue to the connectathon community.
