Ecoin applications present a fundamental module in the Ecoin system that are used to describe a domain of interest and to perform context mediation on data from that domain. We describe the CLAMP tool, which facilitates merging individual Ecoin applications so that the context mediation functionality of two domains of interest are combined in one single application.
