Developing the domain/object platform. domain/object is a new kind of execution environment that blurs the traditional distinctions between tools, languages, operating systems, applications and databases. The execution environment is both relational and fully transparent, allowing the structure of running programs to be queried just like regular application data. domain/object opens the door to powerful new ways to author, debug and deploy software. domain/j is the first application built upon domain/object, and it provides program transformation (refactorings) for the Java language.
