Towards a Software/Knowware Co-engineering
After a short introduction to the concepts of knowware, knowware engineering and knowledge middleware, this paper proposes to study the software/knowware co-engineering. Different from the traditional software engineering process, it is a mixed process involving both software engineering and knowware engineering issues. The technical subtleties of such a mixed process are discussed and guidelines of building models for it are proposed. It involves three parallel lines of developing system components of different types. The key issues of this process are how to guarantee the correctness and appropriateness of system composition and decomposition. The ladder principle, which is a modification of the waterfall model, and the tower principle, which is a modification of the fountain model, are proposed. We also studied the possibility of equipping the co-engineering process with a formal semantics. The core problem of establishing such a theory is to give a formal semantics to an open knowledge source. We have found a suitable tool for this purpose. That is the co-algebra. We also try to give a preliminary delineation of a co-algebraic semantics for a typical example of open knowledge source – the knowledge distributed on the World Wide Web.
