The idea of a global mesh of enterprise composite applications is being impeded by the delay of next-generation interoperable mash-up platforms, providing intuitive human-guided resource interaction, reuse and composition. In this paper we revisit current mash-up platforms and analyze their major shortcomings with regard to the development of real composite applications. Then, we elaborate on a novel reference architecture for a mash-up platform called EzWeb/FAST. EzWeb/FAST facilitates the establishment of a user-centered mesh of interoperable resources that can be composed flexibly and easily to create and execute composite applications based on complex mashupable gadgets. The release of EzWeb/FAST will help enterprises to realize how SOA front-end innovations could make them more productive, responsive and, ultimately, more competitiv
