for those interested, I have been spending this month with Dr Stan Huff's group at Intermountain Health in Salt lake City. I have at least a dozen potential change requests / issues for openEHR. Mostly small, but important in their way. That has come from the evidence of their systems, and our performing a cross-review during this month. The comparison has shown that we (i.e. openEHR and Intermountain) have essentially the same multi-level modelling system, with different details. Plus I have learned a lot in terms of their design philosophy and thinking.
Essentially we can think of these as distilled wisdom/lessons from various incarnations of Stan's leading edge 3M/ASN.1 environment over 15 years, up to the most recent, the Qualibria system using 'CDL' (the ADL equivalent). I'll put these into the openEHR Jira SPEC-PR issue tracker for everyone to see over the next couple of weeks, plus on the mailing lists for more general things I have learned here. The new openEHR Spec programme should get up and running in the next few weeks, which will mean that people here who want to nominate for working on the various specs (i.e. working toward openEHR v2.0) should have a think about doing that. The governance details are mostly worked out, so it just needs people. I know some people feel that the specs have not been changing for too long (myself included) but on the other hand, they have stood up amazingly well over the last few years, and we have a huge amount of industry knowledge accumulated, most of which I think is captured on the PR issue tracker, and at least on the mailing lists. Also, we have a pretty decent ADL/AOM 1.5 spec, which needs community review. AQL has also been implemented a number of times and heavily used now, and has held up very well. There are things to change there, based on its use in industry. So, soon we can start on getting a new version of openEHR... it will be a great opportunity I think, to include the clinical and technical lessons available to us in the next generation platform. The community here is wide-ranging and has a huge amount of knowledge... time to use it! - thomas
