Metadata has been identified as a key success factor in data warehouse projects. It captures all kinds of information necessary to analyse, design, build, use, and interpret the data warehouse contents. In order to spread the use of metadata, enable the interoperability between repositories, and tool integration within data warehousing architectures, a(More)
ConceptBase is a deductive object-oriented database system intended for the management of metadata. A distinguishing feature of the Telos language underlying ConceptBase is the ability to manage rules and constraints across multiple levels of instantiation in so-called meta formulas, thus offering uniform consistency management across heterogeneous(More)
ConceptBase is a meta data management system intended to support the cooperative development and evolution of information systems with multiple interacting formalisms. It supports a simple logic-based core language, O-Telos, which integrates deductive and object-oriented features in order to support the syntactical, graphical, and semantic customization of(More)
