Our more recent approach (see the roadmap document at http://www.openehr.org/Doc_html/Document/roadmap.htm) separates clinical data types, clinical data structures, common abstractions - from demographics, the EHR, the EHR Extract and other things. We see the clinical data types and data structures as a re-usable set of archetypable abstractions that can be used in any model - EHR, demographic, but also drug database and other knowledge resources. We think this general approach is the way of an interoperable future, even if we will spend a bit more time gettinng the details right.To say the least. I think the priorities of the open source health community must be: 1) to point out all the problems of having such information only in proprietary formats 2) to devise an acceptable format for pharmaceutical companies to publish their information (this is the kind of thing an XML DTD is for, no? Though we get into GALEN/GEHR territory when we consider interactions, contraindications, cautions)
With the use of archeytpes, drug type models can be built using the archetype editor, and a drug and interaction knowledge system can be built once (more or less) and used without further modification, while the models of drugs and interactions change and evolve.
Perhaps someone is interested in leading the way on marrying our information and knowledg approach with the actual knowledge and functional needs of drug/interarction databases?

healthcare orgs.
One way forward might be to devise a cut down model that demonstrates the
concepts using the WHO's list of essential drugs. <http://www.who.int/

Is there some way of dividing step 2) in two parts:
i) a quick and dirty design that works soon for those who would like to
demonstrate a top to bottom open source prescribing application quickly
ii) which would anticipate the needs of more sophisticated applications
in future.
The problem is that fairly sophisticated prescribing applications are
here today with automated warnings about interactions. Without them, open
source just will not compete. e.g. <http://www.nhsia.nhs.uk/napps/
