Hi Richard, Are you able to flesh out the use-case a little more?
As Diego has said, cross element constraint is supported by the ADL spec but not by any of the editing tools at the moment. This is not really my field but I think part of the problem is coming up with a rules formalism that can be interpreted by downstream systems In practice I have found that most of the cross-element constraint rules issues are actually required at template level and are cross-archetype ( The classic BMI calculation). This is an area where GDL (http://www.openehr.org/downloads/ds_and_guidelines) is seen as the best solution by most implementers. I am not too familiar with GDL but it might well be possible to use GDL for your purpose Ian Dr Ian McNicoll mobile +44 (0)775 209 7859 office +44 (0)1536 414994 skype: ianmcnicoll email: ian at freshehr.com twitter: @ianmcnicoll Director, freshEHR Clinical Informatics Director, openEHR Foundation Director, HANDIHealth CIC Hon.
