MDA provides an open, vendor-neutral approach to the challenge of interoperability, building upon and leveraging the value of OMG's established modeling standards:
Unified Modeling Language (UML); Meta-Object Facility (MOF); and Common Warehouse Meta-model (CWM).
Platform-independent Application descriptions built using these modeling standards can be realized using any major open or proprietary platform, including CORBA, Java, .NET, XMI/XML, and Web-based platforms.
As new platforms and technologies emerge, MDA enables rapid development of new specifications that use them, streamlining the process of integration. In this way, MDA goes beyond middleware to provide a comprehensive, structured solution for application interoperability and portability into the future.
