## Post #1 by @thomas.beale

Dear all,

I have uploaded drafts of the ADL 1\.5 and corresponding AOM
specification\. These provide support for the last remaining major
semantic gap in templates, namely rules and conditions \(of the kind
required by the NHS CUI project and various other template authors\)\. In
the current release of openEHR, assertions are only partially specified
and practically never used to my knowledge,although the reference parser
does in fact implement them\. However, more powerful syntax and semantics
are needed anyway, to support external queries on patient data, and a
clearer way of defining variables\. The drafts can be found on the usual
wiki page at
http://www.openehr.org/wiki/display/spec/openEHR+Templates+and+Specialised+Archetypes

The template specification drafts will be updated soon to be in sync
with these archetype drafts\.

All feedback welcome\.

\- thomas beale
