A lot of newer projects are looking at object oriented definitions of
EMRs instead of directly relational ones. This work can be made more
specific and concrete by using OO models to create relational tables or
XML schemas, DTDs, archetypes, etc. OO modeling is better able to
capture the complexity of EMR data.
The major work worldwide is the HL7 RIM Reference Implementation Model
(RIM) which is being used as the basis for standards outside of HL7 as
well. They expect to use the model to inform message definition in
version 3 of the HL7 interface standard.
There were other simpler models developed at the NHS (search for the NHS
information model) and for the Good European Health Record (GEHR).
Such models describe the health care system in general and can be used
to guide the development of EMR systems as well as messaging systems and
cross system interfaces.
If you want something more concrete, you can look at the XML work of the
OIO project, FreePM, DocScope, the CEN TC.251 standard (search for
preENV13606) and HL7 Patient Record Architecture (PRA) standard. There
is also the API focussed work of the GEHR project, LANL Telemed, and the
CorbaMed standards.
The two projects specifically focussed on general purpose open source
EMR components are GEHR and DocScope. GEHR is focussed on API access to
the EMR, while DocScope is based on using XML tools to access files in
preENV13606 format.
