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

Abstract

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.
