Draw-together: graphical editor for collaborative drawing

Collaborative object-based graphical editors offer good support for design teams to work concurrently on their design. However, not much research has been done on maintaining consistency when complex operations such as the grouping of objects or working on layers are involved. In this paper, we propose a novel operation serialisation algorithm for consistency maintenance based on the reordering of nodes in a graph. The nodes of a graph represent operations and the edges represent ordering constraints between operations. Users can specify types of conflicts between operations and the policy for the resolution of conflicts.
