At the 2005 Plone Conference in Vienna, Austria, Six Feet Up shared their experience using XUL with Plone for developing rich interfaces for project to manage content other than document-based objects. XUL allows for the development of rich cross-platform custom client interfaces to any Plone-powered site using standard-based technologies such as RDF, XML-RPC, WebDAV and XML HTTP Requests. The talk will be an introduction to the technology and its uses in Plone. The presentation featured a mini case study about a current project where Six Feet Up implemented a XUL interface for managing the day to day operation of an urban design center and interior design firm.
