Quilt: a collaborative tool for cooperative writing

Quilt is a computer-based tool for collaborative writing, which provides annotation, messaging, computer conferencing, and notification facilities to support communication and information sharing among the collaborators on a document. In addition, extensible sets of social roles and communication types are used to provide views of a document tailored to individual collaborators or to other users of the document based upon their position in a permission hierarchy. This paper describes the rationale for and design of Quilt.
