it is certainly the case. See the latest Archetype Workbench for details - http://www.openehr.org/svn/ref_impl_eiffel/TRUNK/apps/doc/adl_workbench_help.htm Start the AWB, set its repository to where your archetypes are, then hit F7. You will see all archetypes being compiled, and .adls files being created by differencing the existing .adl files. Have a look at the .adls files of some specialised archetypes in a text editor. Also, you can use the 'flat' and 'differential' views in the workbench to show the effects of he new representation. > B) If this is so, any ideas wrt dates & tooling etc to support this (inc > wrt the java tooling)? > I can't speak for the Java tooling, but the new version of the reference ADL parser (which is in the workbench) will go into the Archetype Editor during the next few months. Other changes that will be included are described in the new specialisation semantics in the ADL specification. See http://www.openehr.org/wiki/display/spec/openEHR+Templates+and+Specialised+Archetypes for details. As ever the speed of this work is dependent on funding. - thomas beale
