Hi There have been a few issues with DV_IDENTIFIER - largely that all fields are mandatory. This may mean that users puts stuff in that is not helpful. There is also no known set of things to use at any point although this could be expressed in a template (or archetype although this would not be appropriate).
There is a WORKFLOW_ID on every entry that Ocean have been using to link data around a particular workflow - this is the PLACER_ID in HL7 v2. It allows observations, actions etc to be related to a particular instruction. This is working well and keeps things relatively simple. Feeder_audit is a great way to find information about feeder systems and is present in 13606 as well. It is not in the archetype (constrained) but should be visible soon in CKM. I would also suggest that we allow people to use the HL7/ISO datatype names for the models to aid use and familiarity. It will be a diminished set (openEHR compatible) but should meet all the needs of the modellers.
