In a comment on one of my most recent posts, Lloyd McKenzie, one of the main authors of the new HL7 FHIR standard made a comment which I think is important in the discourse about whether openEHR archetypes could be utilised within FHIR resources. To ensure it does not remain buried in the rather lengthy comments, I've posted my reply here, with my emphasis added.
Hi Lloyd,This is where we fundamentally differ: You said: "And we don’t care if the data being shared reflects best practice, worst practice or anything in between."
I do. I care a lot.
High quality EHR data content is a key component of interoperability that has NEVER been solved. It is predominantly a human issue, not a technical one - success will only be achieved with heaps of human interaction and collaboration. With the openEHR methodology we are making some inroads into solving it. But even if archetypes are not the final solution, the models that are publicly available are freely available for others to leverage towards 'the ultimate solution'.
Conversely, I don't particularly care what wire format is used to exchange the data. FHIR is the latest of a number of health data exchange mechanisms that have been developed. Hopefully it will be one that is easier to use, more widely implemented and will contribute significantly to improve health data exchange. But ultimately data exchange is a largely technical issue, needs a technical solution and is relatively easy to solve by comparison.
I'm not trying to solve the same problem you are. I have different focus. But I do think that FHIR (and including HL7 more broadly) working together with the openEHR approach to clinical modelling/EHRs could be a pretty powerful combo, if we choose to.

We need both - quality EHR content AND an excellent technical exchange format. And EHR platforms, CDRs, registries etc. With common clinical archetypes defining the patterns in all of these uses, data can potentially start to flow... and not be blocked and potentially degraded by the current need for transforms, mappings, etc.
