Dear all, due to historical reasons, the name of the attribute connecting HISTORY (was EVENT_SERIES) to EVENT was "items" in the reference model, while in many archetypes (and I believe in some previous examples in RM documents), this attribute name has been the more logical "events". In the current revision of the reference model, it is still "items".
The logical preference would be to raise a CR to change the reference model to use "events", so that archetype paths are more readable. However, we don't have a good idea of the knock-on effect of making such a change on software, or archetypes created by people not using the Ocean Archetype Editor. reactions? - thomas beale -- ___________________________________________________________________________________ CTO Ocean Informatics (http://www.OceanInformatics.biz) Research Fellow, University College London (http://www.chime.ucl.ac.uk) Chair Architectural Review Board, openEHR (http://www.openEHR.org)
