This project presents a framework for the integration of information systems by providing a structurally abstracted and unified communication. This communication is also combined with similarity-comparison methods known as Alignment from Semantic Web Technology. Using implementations of abstract ... [More] Adapters for each IT-platform and conceptual model, this framework is amongst other features a hub and spoke integration system, which transmits five defined Elements of Communication, propagates changes and listens to change events. Each defined Adapter can listen to changes within a model and propagates events at five specific levels into its adapted model. These are classes, subclasses, concepts (individuals), relations (structural and instance) and generic restrictions which can be applied to classes and relations. This framework does not substitute middleware. It makes use of it and exceeds it in a way that communication is lifted on a common, and system and platform independent and comparable level strongly stemming from object-oriented-modeling as well as Semantic Web Knowledge Representation. This communication is supported by integrating methods that are of syntactic nature such as XSLT-Transformations and by semantic methods provided by alignment tools. These transformations are conducted by the integration bridge concept, where adapter-to adapter mapping is processed. [Less]
