Hi Juanita and others, It would be a great research topic and I think one that is needed very badly from openEHR community. If I manage to find an appropriate research position, this would definitely fall within scope of my research as I already have necessary experience and data in endoscopy as explained in my thesis. I have been investigating this subject because of a paper in progress which summarizes my thesis work and I want to inform readers about other studies which claim Archetype bases two-level modelling is superior to classical one in terms of maintainability, interoperability and domain knowledge governance; preferably with objective formal methods. Of course it is hard considering that this is a new paradigm and tricky due to the nature of problem. What I saw is this: formal methods are negligibly scarce and current data is mostly coming from expert opinion. There is a very interesting whitepaper (2004) which explains why single level modelling fails in development and maintenance. It is not really very scientific(?) but you may find it useful anyways:
A Practical Implementation of a Two Level Archetype Based Clinical Model http://www.meridianhi.com/IDME_Whitepaper.htm One last thing about HL7: I read that paper by Ceusters & Smith; it is interesting though but there is another paper as response from HL7 rounds and both seem to tell about facts from different perspectives. I feel that HL7 is over-criticized here and that this would not increase the value of this work for sure. I used v2.4 messages myself and I found it very useful like many. Simply their move with v3 to become a content standard apart from messaging which is then extended to be an EHR standard is not an elegant approach. Maybe we all criticize about this aspect, but then it results in a general dislike about whole HL7. And keep in mind that only time will show who will survive; think about (annoying) existence of cockroaches appearing many million years before elegant species in biologic evolution :D Best regards, -koray Juanita Fernando wrote: > Hiya, > I'm thinking of doing some post doc work in this area later on this > year.
