Ageing societies face tough challenges namely in terms of their ageing workforce and finding new models to accommodate current demographic trends. The application of the collaborative networks paradigm, and a new generation of collaboration-support platforms and tools, is a promising approach to supporting active ageing, and facilitating better use of the talents and potential of retired or retiring senior professionals. As such, collaborative networks can contribute to demographic sustainability. In this context, the results of a roadmapping initiative addressing the implementation of a new vision for extending professional active life are introduced. To support the aimed vision, a strategic research plan for the development of a new digital ecosystem, covering the social, organisational, and technological perspectives, is proposed. A large number of stakeholders coming from different backgrounds contributed to the design and validation of this roadmap.
