  • Aiming at dynamic coordination at runtime, the paper proposes recursive coordination architecture for multi-level hierarchical information systems. It describes the element of system as a self-managed structure, including computing unit, coordinator and coordination space. The computing unit consists of role, actors and services. In order to support actors with multitasks and provide fine-grained coordination, we present a service oriented coordination model based on role for the development and integration of multi-level hierarchical information system. The model classifies coordination into required resource-centered coordination and endeavored service-centered coordination. Coordination among services is achieved by means of coordination space at runtime. The model supports computing units at different levels of granularity and has adaptability to change of organization structure and environment. A real example of commodity trading system illustrates practicability of the model.
