The advances in network-enabled software development raises the demands on the service oriented architecture (SOA). Popular implementations of SOA uses XML-based representations, such as SOAP and WSDL, to enable remote function invocation and service discovery. Our previous experiences show that a sophisticated XML representation is often over-complex for a controlled environment. We also found that the application composition is a high-level operation. Therefore, a proper infrastructure for hosting and delivering various kinds of services is required. We then proposed an XMPP-based solution to overcome these issues. A service is an XMPP client, and focus on how to interact with the other clients, the management of the service can be flexibly arranged through the proposed format of its full JID, and the fundamental security are handled by the XMPP server and the publisher-subscriber pattern.
