A Framework for Integrating Heterogeneous Spatial Information and Applications Adaptively Based on Multi-agent and Web Service

Spatial data is a main carrier and media of social information. But the structure and environment also have some interoperability problems. In this paper, we present a framework for integrating heterogeneous spatial information and applications based on multi-agent and web services. A Contract-First agent model is proposed to interact with the data interfaces of different spatial data providers, which can adaptively serializes the spatial data of multiple sources to be an OGC GIService of the same protocols and interfaces. Then, we introduced a messages conversion agent model, which can adapt multiple requests and response comprehensible information according to individual application.
