Abstract: A system and method for providing a collaborative work environment includes servers and client workstations. Client workstations receive data objects from one or more servers and combine the received data objects with stored templates to render HTML pages representing at least a portion of a common project. Users may view, edit, and create common documents for the projects and upload them to the server using a drag-and-drop interface. Additionally, since all file transfers take place using HTTP, project groups can span corporate organizations as well as time zones and geographic boundaries.
