Enabling End Users to Create, Annotate and Share Personal Information Spaces

The revolutionary advances of Information and Communication Technology push towards the evolution of end users from passive information consumers to information producers. In many contexts, end users are increasingly willing to manipulate content they get from various resources in the Web, move it across the boundaries of their original applications, and integrate it in Personal Information Spaces (PISs), where they can tailor it to their personal needs, use it, and possibly share it with other people. This paper extends our previous work on the definition of paradigms and tools for lightweight construction of PISs, and shows how to address the need for communicating and sharing information with other stakeholders, which emerged during a field study performed in November 2012 with the previous version of our platform.
