Hi,
Does openEHR contain the paradigm to reference instances of archetypes
in template instances ? When I want to use an archetype instance in two
different templates I have two possibilities, 1. to duplicate the data
and store it in the serialized objects of both template instances or 2.
to store the archetype instance once and reference it from within the
template instances. The 2nd option would have the advantage that I could
change the data of the archetype instance and both template instances
immediately would point to correct data. Unfortunately the templates can
constrain the archetype differently any change on an archetype instance
would have to trigger a check on all references of this instance to
ensure that all constaints on the used archetype are still met. This
trigger mechanism doing those checks could be a bit complicated.
If such a reference mechanism is used in openEHR, where in the
documentation is it specified ?
Greetings
Georg
