The DSTU HL7 CTS2 considers that the "Mapping" is done through Associations (inter-code system associations). Associations define the relationships or linkages between concepts or associations....and provide a set of functionality that provides the ability to map concepts and the concept's associated attributes from a source terminology to a concept in a target terminology, or create relationships between concepts within a single code system.»

OMG CTS2: ASSOCIATION is a formal “semantic” assertion about a named entity, in the form of subject, predicated and object including any provenance, qualifiers, or internal BNODEs and MAP is set of rules that associate a set of entity references from one domain into those in another.

The difference in definitions can lead to confusion. Proposition: explain the rationale for the different definitions and then either include this definition in the HL7 CTS2 or the OMG CTS considers it as "out of scope" (align the definitions).
