The emergence of the Maker Movement has taken place in the context of a design practice and research that is now open, peer-to-peer, diffuse, distributed, decentralized; activity-based; meta-designed; ontologically-defined and defining; locally-bounded but globally-networked and community-centered. For many years the author participated and worked in the Maker Movement, with a special focus on its usage of digital platforms and digital fabrication tools for collaboratively designing and manufacturing digital and physical artifacts as Open Design projects. The author's main focus in practice and research as a meta-designer was in understanding how can participants in distributed systems collaboratively work together through tools and platforms for the designing and managing of collaborative processes. The main research question of this dissertation is: How can we support and integrate the research and practice of meta-designers in analyzing, designing and sharing open and collaborative design and making processes within open, peer-to-peer and distributed systems?
