By this, such systems turn out to be similiar to software-systems in many aspects. The well established toolkids of software engineering should prove to be applicable to the development of hyperdocuments as well. The project HEU tries to construct hypermedia systems using suitable specification methods. The object-oriented language DoDL serves as such an approach to generate maintainable systems by using classes and inheritance. An important feature of such a specification is the possibility to characterize the browsing behavior the hyperdocument under consideration.
Feature logic is used here, a sublanguage of first order predicate logic.
Following the idea of DoDL, Systems can be modelled by proper logics used in the context of object-oriented databases. The most necessary question asked is that of the semantics of such systems. We are doing scientific research in this question. At the same time an experimental basis shell be worked out to transform these specifications into HTML coded pages.
