Over recent years, “Internet-able” applications and architectures have been used to support domains where there are multiple interconnected systems that are both decentralized and autonomous. One such domain is the support of data management at the enterprise level. Typically, in these domains, both the schema of the data repository and the individual query needs of the users evolve over time. These query needs can include both the type of data and the required format and structure. To handle this evolution, the resulting architecture must enforce the autonomy in systems that support the client needs and constraints, in addition to maintaining the autonomy in systems that support the actual data schema and extraction mechanisms. At the MITRE Corporation, this domain has been identified in the development of a composite data repository for the Center for Advanced Aviation System Development (CAASD). In the development of such a repository, the supporting architecture includes specialized mechanisms to disseminate the data to a diverse evolving set of researchers. This paper presents the motivation and design of such an architecture to support these autonomous data extraction environments. This run-time configurable architecture is implemented using Web-based technologies such as the Extensible Markup Language (XML), Java Servlets, Extensible Stylesheets (XSL), and a relational database management system
