abstract = {Initially, the Web was developed as a decentralized system
of information repositories that facilitate organizational
knowledge transfer by allowing anyone to create and access
content. However, Web publishing required both technical
expertise and hardware infrastructure. With the rise of the
Web 2.0, social networking sites and content management
systems enabled all users to create Web content. But it
simultaneously put the users at the mercy of the platform
operators. Services could be shut down, erasing content and
disrupting communities. Decentralized community information
systems radically change this dynamic by establishing
participants as equal peers, which form a self-governing
community. This way, a community regains control over their
data, while being able to scale the infrastructure according
to their needs. In this dissertation, we followed a design
science approach that provides support for communities to
create and host their own decentralized community
information systems. On the one hand, we produced several
artifacts to provide possible answers to the question of
what properties such an infrastructure needs to fulfill.
With the blockchain-based decentralized service registry, we
propose a solution for making community knowledge accessible
in a secure and verifiable way. On the other hand, we
transfer the metaphor of educational scaffolding to the
domain of service development. It is based on the idea, that
a scaffold serves as a temporary supporting structure during
a building’s construction phase. As the construction site
develops and the building gets completed, the scaffold
gradually gets removed up to the point, that it is not
needed anymore. With the community application editor,
communities are provided with such a scaffolding environment
for requirements elicitation, wireframing, modeling and
coding their decentralized community applications. Once
deployed on the infrastructure, those applications and
development eff orts remain available, even after the
contributing members might have left, serving as the
community’s long term memory. We demonstrated and
evaluated our artifacts on a European scale, with three
longitudinal studies conducted within several communities
from different areas of technology enhanced learning, such
as the European voluntary service, vocational and
educational training providers and in higher education
mentoring scenarios. All in all, this shift from data being
stored in centralized repositories to a decentralized
infrastructure, hosted by community members, opens up
possibilities for a more democratic and egalitarian
management of community knowledge.},
