Recent Progress in Group Editors and Operational Transformation Algorithms

Опубликовано 6 сентября 2016, 5:14

Group editors are a classic example of Internet-based productivity applications. They allow a group of distributed human users to edit a shared multimedia document over a computer network. Consistency control in this environment must not only guarantee convergence of replicated data but also attempt to preserve user intentions. Operational transformation (OT) is a well-established method for optimistic consistency control in this context and has drawn continuing research attention since 1989. It is promising in fulfilling the speaker's longer-term vision of implementing group editors as a reliable and flexible collaboration medium. This talk interprets the rationales behind group editors and OT, overviews OT-related consistency models and algorithms, and presents some of the latest progress made on this topic by the speaker and his students at Texas A&M University.
