I-DIAG is an attempt to understand how to take the collective discussions of a large group of people and distill the messages and documents into more succinct, durable knowledge. I-DIAG is a distributed environment that includes two separate applications, CyberForum and Consolidate. The goals of the project, the architecture of I-DIAG, and the two applications are described. We focus on technical mechanisms to augment social maintenance and social regulation in the system.
