Google Wave ECF provider

Student: Sebastian Schmidt

Mentor: Mustafa K. Isik

This project is part of the Google Summer of Code 2010


Google Wave is a real-time collaboration system based upon operational transformation approach to replicated state synchronization. With the Cola System (DocShare), ECF has been using operational transformations, for some time now. I will implement a provider to allow an equinox+ecf based web server to inter-operate with Google Wave.

Primary goals

Glass.gif Needs some research

Progress.gif Work in progress

Ok green.gif Feature added

Progress.gif Implementation of a Google Wave ECF provider that people can use to build their own wave applications on top of ECF. The provider will handle the basic wave-protocol operations like managing waves, contacts or documents. Also the provider will provide an api which allows users to add listeners to wave changes and implement real time shared editing applications.

Glass.gif Implementation of real time shared editing support for eclipse. Currently there are cola and docshare, which allow document based real time shared editing for two collaboraters in eclipse. With the help of the wave protocol I want to improve this approach and allow more than two collaboraters to work on one document at the same time. Once you logged into your wave account using the well known ECF ui, you will be able to share a text-based document for collaborative editing with your friends on your or third-party wave server.

On the horizon

In their GSoC welcome package Google told us to "think big and have fun". That's why Mustafa and I already have spoken about ideas we have for the time after the end of GSoC 2010. The wave protocol allows to handle more than one document (= wavelet / blips) in a wave. This feature can be adopted to introduce project-based real time shared editing to eclipse. Hopefully we will be able to share a complete project with our colleagues at some time and work with them collaborative on multiple files and folders in real time.

I would really appreciate to get inspiring ideas from the community. So please feel free to report your ideas.
