Enterprise Architecture Reference Models: A Shared Vision for Service-Oriented Architectures

The business- and mission-driven objectives of service-oriented architectures depend on dynamic interaction of collaborative integrated operations in a federated operational environment. The theme of this paper is that integrated operations can and should be considered service-oriented in a dynamic information environment. In Department of Defense, this dynamic information environment has often been referred to as the global information grid or simply the grid. We describe enterprise architecture reference models as a dynamic abstract reference environment for net-centric collaboration between service-oriented nodes on grid. The complex, dynamic interaction of service-oriented in net- centric environment creates an opportunity to view enterprise architecture as a taxonomy of well-defined systems architectures governed by a set of enterprise architecture reference models.
