| Abstract | Push technology, i.e., the ability of sending relevant informa-tion to clients in reaction to new events, is a fundamental as-pect of modern information systems; XML is rapidly emerg-ing as the widely adopted standard for information exchange and representation and hence, several XML-based protocols have been dened and are object of investigation at W3C and throughtout commercial organizations. In this paper, we propose the new concept of active XML rules for \push-ing " reactive services to XML-enabled repositories. Rules operate on XML documents and deliver information to in-terested remote users in reaction to update events occurring at the repository site. The proposed mechanism assumes the availability of XML repositories supporting a standard XML query language, such as XQuery that is being developed by the W3C; for the implementation of the reactive components, it capital-izes on the use of standard DOM events and of the SOAP interchange standard to enable the remote installation of ac-tive rules. A simple protocol is proposed for subscribing and unsubscribing remote rules. |
