An example application for the publishing industry will be presented. If XML-RPC is to be deployed as a transport for distributed object systems where object methods control the state of various processes, rather than merely disseminate public information, it will be necessary to guarantee that only authorized parties be able to effect the changes. It should be noted that this protocol provides authentication only, and not encryption of the message traffic itself. It guarantees only that the message content originiated from the authenticated party, and was not modified in transit. Also, it is outside the scope of an authentication scheme to provide for authorization, i.e. the definition of roles or ACLs within an application which determine which parties can effect what changes, or have access to what information.

This presentation proposes to focus on the specific problems and experiences associated with using XML in the harvesting and delivery of news on the web. Where XML-RPC or SOAP fits in. Defining a taxonomy for news. Making news content part of a larger distributed application. This presentation will describe how Hotbot is being redesigned to take advantage of a new middle tier, being written in Java, that will deliver search results in XML over HTTP to the Hotbot front-end page servers.
