Abstract: Disclosed in some examples are methods, systems, and machine readable mediums which monitor, archive, and version file system elements stored in one or more different network based file storage systems for one or more different users. Any changes to file system elements stored in the network based file storage systems are recorded and versioned. The system may allow users to revert to a previous version of a file system element, recover a deleted file system element, and the system allows for audits to determine which users placed a file system element in which network based file storage systems and determine which users had access to the file system element in the network based file storage systems. As a result, the disclosed system improves the end-user experience by providing versioning and auditing capabilities as well as allowing organizations to monitor and control their digital property in network based file storage systems.

Abstract: A web application event framework which allows for robust, fully functional web-enabled applications based on real-time interactivity. A web server creates proxies which establish persistent listening objects between a web browser and an application server. The web browser hosts the listener application, as well as a publisher application and the web application event framework, preferably in different HTML frames. Upon request from a user, the web application event framework start controller creates a session object which establishes a persistent connection between the web browser and the web server and maintains a session state. The session object creates one or more application instance objects, which maintain an application state specific to the functionality of the application. The web application event framework application creates a listener to listen for a specific set of events, and each event is published to the web server through the established session object connection.
