Abstract: Disclosed is software architecture and method for sharing data objects among multiple applications in a client device. The architecture includes a server process in the client device for processing a template, such as a SHTML template for the Extended Markup Language (XML), based on a template identifier value received from a user application. Each of multiple applications has a template. Each template identifies a series of objects identified by tag values, such as XML entities, that are to be incorporated into a display page. A database of objects, such as a database of XML entities identified by tag values, is maintained that contains data objects for the applications. An update process periodically establishes a communication link with a remote server and requests download of a data document containing content data corresponding to at least a portion of several of the templates.
