چکیده

Undo is an important feature of editors. However, even after over two decades of active research and development, support of undo for real-time collaborative editing is still very limited. We examine issues concerning undo in collaborative text editing and present an approach using a layered commutative replicated data type (CRDT). Our performance study shows that it provides sufficient responsiveness to the end users.

CIMES: A Collaborative Image Editing System for Pattern Design

In this paper, we present a Collaborative IMage Editing System (CIMES), which is developed for textile pattern design based on our previous image processing system. CIMES adopts a replicated architecture. An image operation representation approach is proposed to reduce the space cost of image operation preservation. Then a concurrent control algorithm is proposed to resolve the image editing co...

Undo in Peer-to-peer Semantic Wikis

The undo mechanism is an essential feature in collaborative editing systems. Most popular semantic wikis support a revert feature, some provide an undo feature to remove any modification at any time. However this undo feature does not always succeed. Supporting the undo mechanism for P2P semantic wikis has never been tackled. In this paper, we present an undo approach for Swooki, the first P2P ...
