A web service for CSCW applications.
ABSTRACT The Open Source Software (OSS) community came with a new paradigm for software development, and the tools commonly used by OSS teams to coordinate their work include version control systems and communication tools. However, there is a lack of groupware support for coordinating the development of OSS projects due to the fact that these tools are non-integrated. In this paper we describe the WS4CSCW, a web service that provides groupware support by integrating communication & coordination tools under a common conceptual model. This work is part of the SAFE project, which aims to develop a framework for supporting the OSS development process.

ABSTRACT: In interactive networked collaborative virtual environment (NCVE), users work in a group to be involved in interactive activities such as game, discussion and learning. However, without having a clearly defined roles and access control of the different level of users, interaction within a virtual environment will not be effectively carried out as these virtual interactions lack of many communication cues as users are physically invisible. Our research uses content analyses to explore various roles, played by users and access rights granted to each role, specifically in e-learning, project management and game. Therefore, we present seven classes of roles based on eight functional activities in a hierarchical and peer to peer virtual organization. A clear role and well defined job function could strictly outline users' access right to ensure smooth communication and secure protection as well as users privacy.

ABSTRACT: In this paper we revisit the concept of session applied to col-laborative work and define a set of operators to manipulate session information related to workspaces and tools schedul-ing in collaborative environments. By means of a proof-of-concept implementation which uses web services and context-aware tools, we show an example of how session information provided by the operators can be used to leverage the ubiq-uitous capabilities of collaborative applications.
