TWC LOGD: A Portal for Linking Open Government Data

International open government initiatives are releasing an increasing number of “raw” government datasets directly to citizens via the Web, creating new opportunities but imposing burdens inherent to the problems of large-scale distributed data integration, collaborative data manipulation and transparent data consumption.
