The FUSION project aims to promote efficient business collaboration and interconnection between enterprises (including SMEs) by developing innovative technologies for the semantic fusion of heterogeneous service-oriented business applications. Such applications may exist either within an enterprise or in several collaborating companies within the enlarged Europe.
