A new project has been created. It is called the Meta Language Markup Language, or MLML for short. The project sets the charter for the next phase of o:XML development work. It incorporates compilers and tools, library development and forms the basis of code transformations.
The language is an intermediary source code format that will allow o:XML and related development to branch out into several areas at once. Different tools and technologies, such as the interpreter, libraries, AOSD and DbC extensions, can be developed independently around a single shared data format. A formal language definition will be published soon.
