Requirements for Distributed Event-Based Awareness in P2P Groupware Systems

Abstract

Abstract-One of the major premises of P2P systems is to enable fully decentralized collaborative functionalities for supporting work teams and P2P communities. Within collaborative systems, tracking and awareness are vital aspects for a successful collaboration. Despite the experience of using awareness in webbased applications, there has been little research in endowing P2P collaborative systems with generic, application-independent awareness mechanisms to fully support collaboration.In this work we present a distributed event-based awareness approach for P2P groupware systems. Unlike centralized approaches, several issues arise and need to be addressed for awareness in P2P groupware systems, due to their large-scale, dynamic and heterogenous nature. In our approach, the awareness of collaboration will be achieved by using primitive operations and services that are integrated into the P2P middleware. As a first step, we identify the major requirements for such an event-based awareness approach, including dynamics of events, genericity of events, lightweight mechanisms, automation via the use of rules, as well as event transformation, presentation, propagation and notification services in order to fully support timely awareness of collaboration activity. We then propose an abstract model for achieving these requirements and we discuss how this model can support awareness of collaboration in mobile teams.

On Sharing and Synchronizing Groupware Calendars Under Android Platform

“…Awareness can take various forms such as availability awareness (availability of resources, availability of members, ...), context awareness (where the actions/changes took place), group process awareness (changes with regard to project workflow), etc. [17], [25]. Implementation of these awareness forms enables a timely and effective collaboration and coordination of online groups.…”

“…Indeed, while in the recent past, collaborative group work was based on the web and peer-to-peer applications [17], [25], now most of the group work goes mobile. The use of mobile devices gives a new dimension to collaborative group work, which is not possible with Web-based group work, namely, the members of a group cannot only be geographically distributed, they can also do collaborative work on the move, anytime, anywhere [14] in both online * SmartLearn Group, Universitat Oberta de Catalunya, Spain and offline modes of work [26].…”

Awareness in P2P Groupware Systems: A Convergence of Contextual Computing, Social Media and Semantic Web

“…To this end we are exploring the provision of service-based group awareness capabilities within the P2P middleware on top of which groupware applications can be developed [22]. Also, unlike existing approaches that provide awareness information directly from streams of events, we are proposing event transformation capabilities to achieve presentation of information in different formats, tailored to group members' needs and to their computational resources.…”
