Hello everyone,
I have been trying to found information about ADLs, but there is no
information on current (1.4) ADL document.
Searching the wiki for 'ADLs' doesn't work as returns all 'ADL' results.
Do you know where the documentation about ADLs can be found?
Regards

Diego,
if you mean the ADL 1.5 format, see the specs at the bottom of [http://www.openehr.org/svn/specification/TRUNK/publishing/roadmap.html](http://www.openehr.org/svn/specification/TRUNK/publishing/roadmap.html)

I mean ADLs as referenced here
[http://www.openehr.org/224-OE.html](http://www.openehr.org/224-OE.html)
".adls, for 'ADL source' files, allowing specialised archetypes to be
represented 'differentially' (like object-oriented subclasses)"

For the tool, see [http://www.openehr.org/svn/ref\_impl\_eiffel/TRUNK/apps/adl\_workbench/doc/web/index.html](http://www.openehr.org/svn/ref_impl_eiffel/TRUNK/apps/adl_workbench/doc/web/index.html)
For the wiki page see [here](http://www.openehr.org/wiki/display/spec/openEHR+Templates+and+Specialised+Archetypes) - you can see a lot of examples here.
otherwise see the links on the page I mentioned below for the syntax (see sectoin 10 of the ADL 1.5 doc). Note that .adls files are just .adl files for most archetypes, but for specialised archetypes, the format is ‘differential’, meaning that only changes with respect to the parent are indicated, not the whole content.
hope this helps,
