Abstract:
Today’s Information Systems and Enterprise Applications require extensive use of Metadata information. In Information Systems, metadata helps in integration and modeling their various components and computational processes, while in Enterprises metadata can describe business and management models, human or physical resources, among others. This paper presents a light and no-cost extensible Metadata Repository solution for such cases, relying on XML and related technologies to store, validate, query and transform metadata information, ensuring common operational concerns such as availability and security yet providing easy integration. The feasibility and applicability of the solution is proved by a case study where an implementation is running in operational state.
