| Summary: | Research focus of the paper are heterogeneous information systems. Heterogeneity within a set of software applications can be attributed to the fact that their collaboration is hindered due to the conflicts in software architecture, communication protocols and/or data representation. General interconnectivity and emerging interoperability have caused the fall of mainframe-based systems, which in turn led to variety of information systems with local data representations, communication protocols and software architectures. Today these information systems need to collaborate in different engineering projects. Existing approaches, such as common framework, integration with standard scheme and data mediation, try to diminish the undesired effects within heterogeneous systems. The approaches are indeed successful because they eliminate all conflicts at design time. This way collaborating applications have to abandon their local data views. In this paper heterogeneity is regarded as a property of an information system while disharmony of an information system is defined as a state of the system. Further, structural, semantical and functional disharmony is defined as part of overall information systems’s disharmony. As a consequence a new methodology called DRAGOn (Disharmony Resolving with Agents and Ontology) is proposed. The methodology aims to dynamically resolve structural and semantical disharmony by preserving applications’ local data views. Another novelty is the definition of conceptualization for structural and semantical disharmony (Disharmony ontology) and the use of software agents. Disharmony ontology is specified in OWL. The agents use the ontology for resolving of structural and semantical conflicts between applications at runtime. Agents communicate via shared communication space based on Java technology. The mediation is incremental, which means that agents are able to build their local ontologies. The ontologies are used as persistent meta-data repositories of concepts (structure and semantics) that are captured from applications during runtime.Extensive applicability of the DRAGOn methodology is expected in information system clusters with rich and complex data content, namely management of construction projects. |
