Newman-Wolfe, R. E., Webb, M. L. and Montes, M. (1992): Implicit Locking in the Ensemble Concurrent Object-Oriented Graphics Editor. In: Proceedings of the 1992 ACM conference on Computer-supported cooperative work November 01 - 04, 1992, Toronto, Ontario, Canada. pp. 265-272. Available online

Ensemble is an X-Windows based, object-oriented graphics editor based on the tgif graphics editor from UCLA. It relies on Unix 4.3bsd sockets and can be used as a stand-alone program or as an application in the University of Florida's distributed conferencing system (DCS). It uses implicitly placed write locks for concurrency control, with locks placed when an object is selected and removed when it is deselected. Multiple users may read or edit a file concurrently, with all users receiving updates whenever a lock is removed. Pointers are shared by mutual consent, so that users may collaborate to the degree desired. Ensemble is a prototype lock-based approach to object-oriented concurrent graphics editing.

Newman-Wolfe, R. E. and Pelimuhandiram, Harsha K. (1991): MACE: A Fine Grained Concurrent Editor. In: Jong, Peter de (ed.) Proceedings of the Conference on Organizational Computing Systems 1991 November 6-8, 1991, Atlanta, Georgia, USA. pp. 240-254. Available online

MACE is a distributed program running on the X Window System and Unix 4.3bsd sockets that permits fine-grained (character-level) concurrent editing of text files. It runs both as a stand-alone program and as an application in the University of Florida's distributed conferencing system (DCS). MACE uses write locks for concurrency control, allowing a locked section of text to be bounded by any pair of characters in the file. Multiple users may read or edit a file concurrently, with all users receiving updates whenever a lock is removed. The level of sharing is controlled by mutual consent, so that users may collaborate to the degree desired, including the option to view updates in real time. MACE is a first step towards a fine-grained, lock-based approach to concurrent text editing.
