Issue 18815: EXPRESS MM MOF model does not include the UML InstanceSpecifications in the specification (express-rtf) Source: NIST (Mr. Edward J. Barkmeyer, edbark(at)nist.gov) Nature: Revision Severity: Summary: The EXPRESS MM specification defines three Packages -- BuiltInTypes, BuiltInConstants, and GenericTypes – that contain UML InstanceSpecifications. It also contains the Instance INDETERMINATE in the Instances package. These InstanceSpecifications represent predefined elements of the EXPRESS language that are instances of more general classes (of types and values) defined in the language. Because MOF does not support InstanceSpecification, the v1.0 MOF model does not contain any representation of these model elements. Standard representation of these model elements is critical to interoperable interchange of EXPRESS models. Some MOF-compatible representation of these model elements must be included in the specification and/or the normative artifacts.
