Archetypes provide constraints on an underlying reference information model. There are ongoing efforts within HL7 to provide reusable 'chunks' of the RIM that are at a level that makes them useful for interpretation and re-use. But progress is slow. An alternative approach has been taken thus far in Europe and elsewhere with the progression of the CEN/ISO 13606 standard, principally Part 2 which describes the form of data extracts, structured with archetypes. Archetypes were described originally by the openEHR community and the EN 13606 standard is slightly less complicated but follows a similar form. It is a stable format however, while the openEHR ADL version is under constant review and change.

The Medical Objects template editor saves and loads ADL according to the 13606-2 standard (ADL v1.2) and it can export in a xml format that supports extended semantics (the template functionality), including GELLO event handling. We use the HL7/ANSI standard GELLO v. 1 as a 'scripting' language for node value validation, initialisation, calculation and visibility. Constructs are also tagged and editable for HL7 v.2 message generation. Datatypes are mapped accordingly. Example data can be created in HL7v2 format using the Australian Archetypes in V2 draft standard approach. A working GELLO interpreter/IDE is included in the editor.

Our aim is to further develop the editor and thus we can now import HL7 v.3 templates as well as openEHR archetypes. We are exploring export and import of openEHR (with ADL v. 1.4), and HL7 CDA and HL7 mif.

This version has been an internal tool until now but in the interests of interoperability and progression of eHealth we have decided to release a free version of the editor.
