In recent times, Wikipedia has opened the way to massive collaborative editing. More specifically, it has demonstrated what can be achieved with a massive collaborative effort. Massive collaborative editing implies scalability and pessimistic replication scales poorly in the wide area. Optimistic replication offers better performance but has severe drawbacks for maintaining consistency. In this paper, we propose a new optimistic replication algorithm for massive collaborative editing called WOOT. It is designed to scale as well as to ensure eventual consistency and intention preservation. It is important to point out that WOOT's efficiency does not depend on a number of sites and can be deployed on a very large, pure peer-to-peer network.
