The basic way to realize reusability, share and interoperability in M&S is standardization. A number of open standards have been proposed to solve interoperable problems in their own domain, which promotes the development of simulation technology. Many researches have been done about the specification and application of the standards themselves. What has rarely done is the establishment of a wide-reaching demonstration or test environment within which the mutually supporting (and possibly conflicting) capabilities of the various standards can be put on display for evaluation and education. First, five emerging open standards (MDA, BOM, SRML, MSDL, C-BML) were selected and described, then an XMSF case was given and the integration and analysis of the five standards were elaborated. Finally, the effect of “taking open standards together” was deduced and summarized, which might benefit the present simulation industry.
