The UML specification is maintained by the Object Management Group (OMG).
Another important OMG specification is MDA (Model Driven Architecture) which is a software development approach the OMG announced as long ago as 2001: it has been influential though has limited take up in many industry sectors. MDA supports a form of code generation and provides a set of guidelines for structuring specifications expressed as models as described in Chapter 2 (Section 2.4).
