XML Dataspaces for Mobile Agent Coordination

This paper presents XMARS, a programmable coordination architecture for Internet applications based on mobile agents. In XMARS, agents coordinate – both with each other and with their current execution environment – through programmable XML dataspaces, accessed by agents in a Linda-like fashion. This suits very well the characteristics of the Internet environment: on the one hand, it offers all the advantages of XML in terms of interoperability and standard representation of information; on the other hand, it enforces open and uncoupled interactions, as required by the dynamicity of the environment and by the mobility of the application components. In addition, coordination in XMARS is made more flexible and secure by the capability of programming the behaviour of the coordination media in reaction to the agents' accesses. An application example related to the management of on-line academic courses shows the suitability and the effectiveness of the XMARS architecture. Keyword...
