Open, collaborative task management in Web 2.0

This paper presents the Collaborative Task Manager (CTM), which offers a unified management of shared tasks and commitments involving the usage of heterogeneous applications. The CTM supports the synchronization of user activities, and the management of workspace awareness, in customized collaboration environments. In particular, the CTM enables the user to resume the activity context of a task, by providing direct links to artifacts developed by using multiple applications. Moreover, the CTM supports a task aware workspace awareness management, enabling the user to receive the notifications concerning each specific task in an organized way, and to access a workspace awareness space structured on the basis of her/his tasks.
