I am not sure what you mean by this William...there isn't any special 'OpenEHRstring' - in openEHR, all those 'inbuilt types' are assumed - see the Support IM - http://svn.openehr.org/specification/BRANCHES/Release-1.1-candidate/publishing/architecture/rm/support_im.pdf - Same goes for Integer, Real, Boolean etc. This was one of the points of departure from HL7, which redefined all the basic types (INT, REAL, ST, BL etc). > > This can only be solved if we step back from the technical data > specification and use the clinical data specification as point of > reference, map from there to CEN, Open EHR, ISO, HL7 v2 and v3.

The data types in openEHR have largely been driven by clinical input (particularly expert pathology input) and archetyping experience. But they are of course technical artifacts, else we cannot write software...
