If we would later go by one of the URN suggestions in DV_EHR_URI-related Issues - Specifications - Confluence (atlassian.net) and register the openehr URN, then that uri example could instead be urn:openehr:archetype:openEHR-EHR-OBSERVATION.laboratory_test_result.v1
Context: We are at Karolinska University hospital currently starting to look at two-way conversions between openEHR templates and FHIR Questionnaires for some use cases where we need to use some already available form services. We thus found this thread interesting. If anybody has done more in this area after the posts above, please share your experiences.
