well, we hope obviously that they will be very close - when I said 'not compatible' I only meant that purely automatic processing using BPv2 of data built with BPv1 won't quite work 100% correctly. This is why there is a rule in openEHR (open to debate of course) that each new 'version' (BPv1 -> BPv2 -> BPv3 etc) has to carry with it a little conversion algorithm (at least an xslt converter) that can be used by systems. It will be a while before we get this properly standardised, but I think people can see intuitively how it might work - either for once-off data migration or for on-the-fly processing. I would hope to be able to convince IHSTDO to think about Snomed (or Snomed-like) concept ids for archetypes. > > then we can have > openEHR-EHR-Observation-SnomendCTConceptNameSNomedCTconceptId87654321. yes, that's the idea. > > If the concept is non existing in Snomed CT, there are procedures to > ask for the addition. > > Due to fine grainedness of SNomed CT to a high level it is probably a > lot that can be handled with this, also avoiding the same concept used > for 2 different archetypes. > > I agree with the world wide management of this, but then again the ISO > / CEN / HL7 / CDSIC DCM approach (IHTSDO invited) would be helpful. Personally I think it should be IHTSDO - this organisation has been set up for just this purpose and has the right people. The other standards don't have the same board membership model and have historically been far too diffuse with respect to terminology. I still don't quite get what way DCM is going - I thought it was going with archetypes, based on the meeting a year ago, but in any case, I think the job of standardising clinical models must be done by clinical people, and on a far more agile basis than any of the official standards organisations. - thomas * *
