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 ( ) 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.
