Dear all,
Due to CR-000110 passing a vote in the openEHR ARB (http://www.openehr.org/about_openehr/t_arb.htm), the Archetype Definition Language (ADL) document has had a major update. The Archetype Object Model (AOM; a UML model of archetypes) has also been made official in the specification repository. You can find these documents at http://www.openehr.org/repositories/spec-dev/latest/publishing/architecture/top.html (see links in the green section).
The parse specification for the dADL part of ADL has changed quite a bit. The openEHR tools will support both old and new dADL for some time to come, however, not all of the language changes are yet incorporated in the tools.
THe ADL specification is becomg quie mature, and we would expect only minimal syntax changes going into the future. THe AOM document is younger, but has been heavily reviewed, and comprises thinking from tools developed by Ocean Informatics, the DSTC (dstc.edu.au), UCL and others working in clinical and ontology projects around the world. The AOM will continue to develop, so expect some changes into the future, but not radical ones.
