Spatial semantic network and agent-based framework for spatial information interoperation

In this paper, we study on an agent approach for synergetic management of the heterogeneous spatial information on the network. First, we focus on establishing a semantic network model for spatial information based on extended spatial metadata; secondly, we propose an agent-based interoperating framework among heterogeneous spatial databases based on spatial semantic network model; lastly, according to the framework, we implement a core agent system named PKU Agent System (PAS) for spatial information interoperation on the network using Java language.
