Bring together information about creatorscreators now hidden within library, archival, and museum contexts, using a social networking model. Broaden the view of "authority work" beyond NACO contributors. Increase metadata creation efficiency. Make it easier for users to identify works by or about the same creator users to identify works by or about the same creator regardless of language or discipline. Expose information about personal and corporate bodies beyond the confines of library, archival, and museum silos and bring them into the "network flow".
