This part of ISO 16100 specifies the methods and rules for matching existing manufacturing software unit (MSU) capability profiles and required capability profiles derived from multiple capability class structures. The methods and rules allow MSUs in manufacturing applications to be evaluated for interoperability and, in some cases, for interchangeability. The following are outside the scope of this part of ISO 16100: - services for creating, registering and accessing the various templates for the reference manufacturing domain models, the manufacturing domain data and the capability class structures; - the conformance tables that reference Type 1 services defined and specified in ISO 16100-3; - additional services needed for managing these templates in a database or equivalent object repository.
