Welcome to the discussion forums for the Open Cooperative Web Framework project. This discussion group is intended for developers (users) who are considering or have already started using the framework.

The Open Cooperative Web Framework enables the creation of cooperative web applications featuring concurrent real-time interactions among remote users and external data sources. The framework handles remote notification of user changes, the resolution of conflicting changes, and convergence of application state with minimal information from the application.

The current implementation of the framework is based on open web technologies such as Dojo, cometD, Bayeux, and WebSocket. The framework includes:

* A JavaScript API for sending and receiving coweb events
* An JavaScript *operation engine* using operational transformation to resolve conflicting, simultaneous changes
* A Python coweb server built on the Tornado web server
* A Java coweb server built on cometd-java
* API documentation, tutorials, and examples
