In this paper, we present the collaborative environment reference architecture (CERA) with the aim of supporting collaborative work environment (CWE) interoperability. The vision of CERA is to support users who are engaged in common collaborative spaces with similar work processes to work and collaborate seamlessly together, despite their use of proprietary CWE tools and systems. The underlying CERA concepts, design principles, and models are discussed, as well as the architectural decisions made as a result of the extended requirements analysis exercise. Furthermore, we present results from the Ecospace (http://www. ip-ecospace.org/) project as an example of a CERA instantiation which focuses on facilitating users collaborating across different CWE systems, namely BSCW, NetWeaver, and BC. We conclude with future research and implementation directions.

Abstract. The transfer of the mashup paradigm in corporate environments needs additional capabilities beyond those typically associated with consumer mashups. In this paper, we present the architecture of the FAST platform which allows creating enterprise-class and multi-channel visual building blocks (so called gadgets) in an ad-hoc manner. The design of complex enterprise-class gadgets is supported by an integrated semantic concept which hides the complexity from the actual users. The architectural components of the platform, a technical life cycle model for enterprise mashups, and the FAST gadget ontology are presented. By means of a cross-organizational real-world scenario from the marketing/ promotion event area, we demonstrate the value and potential of the FAST platform.
