Simulation models and their metainfo-management using RDF-based paradigms

In a catalogue for computer-based models the basic problem is that complex interdependencies between models must be addressed, which are dependent on an application´s domain. Thus, when describing and exploiting models, researchers experience the proverbial needle-in-a-haystack routine. What is needed is a system similar to a library´s card catalogue, such that metadata is captured in a central location that addresses sufficient model summary information and its interpretation. The goal is to develop such a catalogue system independent from an application domain for managing metadata and providing metainformation (metainfo) about computer-based models. Metainfo is by our view the logical conclusion of metadata. We address the construction of an ontology-based system from an application and architectural point of view. We explain why and how one should construct a RDF(S) based system for supporting collaboration via the Internet and intranets. The innovation of this solution is the integration of existing modelling applications by providing a set of Web service-based APIs with our platform. This enables to process metadata automatically without manual user interaction.
