Within the ROLE European research project, an interoperability framework has been developed to support self-regulated learning and to enable learners and teachers to create personal learning environments (PLEs). This framework enables learners to assemble tools, services and resources together to create their own custom learning environment. This chapter discusses the overall architecture, the specific components of this architecture and the platforms in which we have integrated the ROLE framework. Additionally, we share the lessons learned from the design and development. Furthermore, we discuss our experience with the ROLE development infrastructure and our collaboration within the ROLE development team and with several open-source projects.

With the evolution of the Internet from a controlled research network to a worldwide social and economic platform, the initial assumptions regarding stakeholder cooperative behavior are no longer valid. Conflicts have emerged in situations where there are opposing interests. Previous work in the literature has termed these conflicts tussles. This article presents the research of the SESERV project, which develops a methodology to investigate such tussles and is carrying out a survey of tussles identified within the research projects funded under the Future Networks topic of the FP7. Selected tussles covering both social and economic aspects are analyzed also in this article.
