OpenCoweb - Project Overview
The Open Cooperative Web Framework provides JavaScript enablement of concurrent real-time interactions among remote users and external data sources. This emerging class of applications is referred to as cooperative web applications. The framework handles remote notification of user changes, the resolution of conflicting changes, and convergence of application state using Operational Transformation algorithms. The objective of the framework is to support cooperative web concepts across all browsers and devices.
The framework is intended to serve as a building block for web application developers who seek to develop solutions that can be used by a single standalone user or simultaneously within a workgroup of remote users. The framework supports Websocket and OpenAjax Hub technologies as well as the cometD Bayeux protocol. Web application developers can use the Cooperative Web API to enable JavaScript UI Controls and Widgets with simultaneous user interactions within a online meeting. JavaScript UI libraries such as the Dojo Toolkit can be enhanced with OpenCoweb.
Features
The framework is based on open web technologies such as Dojo, cometD, Bayeux, and WebSocket. The framework includes:
- An JavaScript operation engine using operational transformation to resolve conflicting, simultaneous changes
- A JavaScript API for sending and receiving coweb events
- A Python coweb server built on the Tornado web server
- A Java coweb server built on cometd-java
- API documentation, tutorials, and examples
Commit Status
OpenCoweb has establish a TestSwarm installation for distributed continuous integration testing for the framework.
These tests provide insight into the compatibility of recent JavaScript code commits with respect to a variety of supported browsers.
