Aftermath 1
The presentations from the four panel members generated a (sometimes heated) discussion. Several speakers pointed to existing implementations of the RIM (contradicting one claim in Smith's presentation, to the effect that there are no implementations of the RIM). In discussions subsequent to the public part of the meeting, however, it proved that in several of the mentioned cases it was not the RIM itself which had been implemented, but rather some version of the RIM which had been fixed up to make it implementable.
Aftermath 2
It is interesting that both of our interlocutors accepted that there are problems moving from design to implementation of HL7 V3. Yet still they see no problems in the fact that HL7 V3 has been declared an ISO standard.
Aftermath 3
Both of our interlocutors insisted that they want critics to join the HL7 movement, rather then throwing potshots at the RIM from the outside; otherwise, they say, HL7 will not pay attention to what we have to say. But some within HL7, including our friend Gunther Schadow, are already paying attention. And surely this is right: if problems are found in an endeavor of such importance for the future of healthcare and of healthcare information technology, then it should be incidental who points out these problems. What is important is that they are fixed.
Aftermath 4
We brought arguments to the effect that important aspects of HL7 RIM can be supported by no known reasoning systems; other aspects are incompatible with the reasoning systems underlying important terminology initiatives such as SNOMED CT and NCIT. In response, our interlocutors insisted that HL7 RIM it is just a messaging standard; thus it does not matter if it does not support reasoning. But does this jibe well with other claims being made on behalf of the RIM, including claims made at this very panel?
