适用范围：Most inter-tool data transfer standards deal with protocol and syntax of the transfer, with a shared semanticbasis assumed. This standard provides an explicitly defined metamodel (and meta-metamodel) forspecifying system and software behavior. It defines a semantic basis of observables that allows each tool,whatever its own internal ontology, to communicate facts about the behavior of a subject system asprecisely as the tool’s metamodel allows. Conventional tool model elements are reduced into simpler,directly observable fact statements about system behavior. This metamodel is much expanded over theoriginal metamodel for software behavior in Part 3 of IEEE Std 1175™-1991.This reference model provides a common interpretation basis by which tools may express andcommunicate the observable features of system/software behavior to users and to other tools. Toolsincorporating this metamodel in their import/export facilities enable engineers to interconnect best-in-classanalysis and specification tools for integrated problem solving. Another feature of this metamodel is that it provides a specification that is directly testable. Finally, the provision of an explicit meta-metamodelenables tool builders to extend the reference metamodel for particular purposes.
