The management of organizational knowledge has become increasingly important since knowledge was identified as the new basis of competition in post-industrial society. One of the key issues in knowledge management is to put knowledge into a repository where it can be easily stored, reused and re-created. This paper proposes a model repository and a type of knowledge management using a new repository system. The emphasis of the model repository is on abstracting knowledge in the form of schematic models. Major benefits include model independence and model integration. A metaschema is constructed according to six conceptual components that can include a variety of models. A case and prototype system illustrate the practical feasibility of model repository and knowledge management.
