MDA的标准化努力基本上是跟UML同步的

Q: Can you tell me something about the history of the MDA?

A: In 1996, OMG expanded its scope to include modeling and in 1997 adopted the Unified Modeling Language (UML)® and Meta-Object Facility (MOF™). Although it has always been true that UML models can be implemented on any platform, the continuing proliferation of middleware "silver bullets" suggested that a platform-independent MOF-based model is the secret to software stability and ROI - a stake that remains fixed in the ground while the infrastructure landscape around it shifts over time. The MDA unites OMG's well-established modeling standards with every middleware technology - past, present, and future - to integrate what you've built, with what you're building, with what you're going to build. Rather than focusing on yet another "next best thing," MDA raises the bar and designs portability and interoperability into the application at the model level.
