What applying of the ODP viewpoints teaches us about tool-chains

For some time, we have focused our research on the generic B2B middleware services for managing inter- enterprise communities of autonomous business ser- vices. In contrast to some earlier papers where the rela- tionships between the Pilarcos concepts and their coun- terparts from the ODP-RM are shown, this paper ap- proaches the management system for inter-enterprise communities itself as the ODP system of interest. The lessons learned underline a number of research chal- lenges we are currently working with, especially for the B2B middleware repositories, their federations, and service development tools relying on the federated repos- itories.
