xframe is a project about schema based programming hosted at www.sourceforge.net.
We focus on XML schema as the starting point of application development. Derived from the schema we automatically generate business models, GUI's, mappings and more. It's somehow a quite abstract variation of MDA (model driven architecture).
There are several existing tools like JAXB from SUN Microsystems to automate some of these tasks, but out of several reasons they are not useful for use. For example with JAXB the schema must be known at compile time. But what we need is a runtime schemas processor.
