Microsoft recently turned over the DCOM specification to the OpenGroup. DCOM is a binary specification; where there is a discrepancy between the spec and the original source code, the source code is the authoritative reference. |

| Although it might appear that many middleware standards are at work, this impression is misleading. Middleware is a collection of services, so there is no specific middleware "standard," per se. Instead, standards that apply to the i ndividual segments and interoperability methods within middleware are needed. Consolidation of various middleware pieces may make life easier for developers, but a lack of standards will hind er network managers' efforts to promote the free interchange of middleware services. |
