Abstract : Distributed collaborative systems allow users to collaborate on a set of shared documents from any place, at any time and from any device. Examples of collaborative systems are wikis, version control systems or GoogleDrive. While 30 years ago when these collaborative systems were firstly developed they were used in scenarios involving only a small set of users such as for the writing of a research article, nowadays we notice a change in the scale from several users to a community of users. The large-scale collaboration is now possible due to advances in mobile and ubiquitous communication that enable users to be continuously connected and to the appropriation of existing tools by the users. However, existing collaborative systems face several challenges including privacy issues as personal user information is placed in the hands of large corporations and users have little control over the usage of their data, performance and coordination issues in the large-scale context. In this talk we will illustrate the evolution of collaborative systems in the past years and describe our vision of trustworthy distributed collaborative systems where communities of users can safely and confidently collaborate without the use of a central authority. We will focus on envisaged solutions for replicated data consistency, security, trust and awareness in this context. As human factor is a key issue in the design of trustworthy distributed collaborative systems, we call for the need of evaluation of these systems with user studies.
