Abstract: A method, system and computer program for processing data objects in a distributed data processing system, said distributed data processing system having a plurality of software and/or hardware nodes being communicatively connectable. The method comprises the steps of defining first and second environments for processing objects at differ levels of abstraction, namely a first platform independen level and a second platform dependent level operating with different categories of object aspects. Each object is defined according to two object models, one for the platform independent environment and one for the platform dependent environment. The two object models are syncronized and object instances generated on the basis of said models are processed in the respective environments dependent on the aspects of the current object instance.
