Hello!
Could you tell me, please, how can I constrain the archetype displaying (or only the one field of the archetype), according to the sex (age) of a patient?
Thank you,
Leysan
Hi Leysan,
Archetypes are for content definition, not to define rules on field displaying on GUI.
That should be part of a GUI directive, maybe inside a GUI Template. http://www.openehr.org/wiki/display/impl/GUI+directives+for+visualization+templates
I think she is referring to something like "if patient is male then
obstetrics field should be null", and those are created as invariants
Hi,
As I understand this is an issue related with semantics rather than presentation as it reads. Therefore I'd say you'd define the rule in Invariant/Rules section of the Archetype (I might be wrong with the naming though).
But as we go into real implementations some dodgy things start to come out; that you can't always separate semantics of information from presentation. For the latter GUI Directives, a new shadow model if you like, will solve the problem. However how to solve the issue with the semantics and link presentation to it consistently is a difficult question. That's why I still believe (sorry purists will hate me but), as they do in CDA - the way clinical information presentation has also a meaning in real practice, and we should be expressing it within Templates if not Archetypes.
Thanks for raising this issue, so let the discussions begin 
Cheers,

My understanding as well. ADL 1.5 will make this possible e.g., with a rule in the archetype like: where 12345 is the term for female. - thomas
