2. The problem
Information processing systems often turn out to be non-interoperable
They could not be used together for supporting the whole information processing cycle
3. The aim of the work
A unified web-based bank of knowledge for
- supporting development of interoperable information processing systems,
- supporting the whole information processing cycle,
- supporting coordinated researches on methods of solving various information processing problems
(scientific aspect),
- providing trainees with means for solving training tasks in the field of information processing
(educational aspect)
