Hi Pablo, there are three C_xxx special types, that allow CODE_PHRASE, DV_QUANTITY and DV_ORDINAL to be more conveniently constrained than if the standard C_COMPLEX_OBJECT approach were used: C_CODE_PHRASE, C_DV_QUANTITY and C_DV_ORDINAL. These types are described in the openEHR Archetype Profile <http://www.openehr.org/svn/specification/TRUNK/publishing/architecture/am/openehr_archetype_profile.pdf> (There is no C_CODED_TEXT type defined there). Our experience is that these types are used nearly universally because they express the typical semantics much more easily that the standard ADL would. The parent class C_DOMAIN_TYPE is the plug-in point for more such classes. - thomas -------------- next part -------------- An HTML attachment was scrubbed...
