What is the main difference from the object-oriented paradigm?
The object-oriented paradigm is aimed at studying objects while the concept-oriented paradigm generalizes this approach by considering also spaces, which are claimed to be at least as impotent as objects. More concretely, the concept-oriented paradigm is aimed at studying representation and access functionality implemented by spaces rather than object functionality (business methods) implemented by objects. The space functions are at least as important as object functions and for complex systems they even account for most of the system complexity. In other words, in system development it is more important what happens on space borders rather than in objects themselves.
