An Ontological Sw Architecture For The Development Of Cooperative Web Portals

Ontological technologies comprise a rich framework of languages and components off the shelf, which devise a paradigm for the organization of SW architectures with high degree of interoperability, maintainability and adaptability. In particular, this fits the needs for the development of semantic web portals, where pages are organized as a generic graph, and navigation is driven by the inherent semantics of contents. We report on a pattern-oriented executable SW architecture for the construction of portals enabling semantic access, querying, and contribution of conceptual models and concrete elements of information. By relying on the automated configuration of an Object Oriented domain layer, the architecture reduces the creation of a cooperative portal to the definition of an ontological domain model.
