Conformance

Conformance of a data or software artifact to an openEHR specification is determined by a formal test of that artifact against the relevant openEHR Implementation Technology Specification(s) (ITSs), such as an IDL interface or an XML-schema. Since ITSs are formal derivations from underlying models, ITS conformance indicates model conformance.
