A case study on industrial requirements management was performed in a Swedish automotive supplier of software-intensive systems. Based on this case study, a frame concept for integrated model management is proposed. One core element in implementing this frame concept is an ontology-based domain repository. Concepts, architecture and realization of a domain-repository are introduced. The domain repository is based on RDF, RDFS and TRIPLE and includes extensions supporting navigation in the artifact net and derivation of new knowledge: Modlets, Actlets and Spot Views.en004conference paper
