Association Types in the registry

Association types are concepts in a special taxonomy: The classification scheme is named AssociationType. For any association type, there is an immediate concept child. The concepts value is the actual name of the association type, not to be mismatched with the so-called "forward label" (the concepts name), or the "backward label".

Association type concepts can be obtained by invoking the method findAssociationType(String) in the class RegistryFacade.
