Federated event propagation in distributed social networks

Distributed and in particular federated infrastructures are increasingly common on the Internet. As opposed to centralised systems, they pose challenges concerning the shared access to data and information. Federated social networks are widely affected due to the high dynamics in content production or modification and churn among the participants.
A representative problem is the propagation of event invitations among the participants of instances (pods) of the social network software Diaspora. This is a major obstacle for potential users compared to having such functionality integrated in centralised social networks. In this master thesis, the RSVP event invitation mechanism shall be analysed and implemented for Diaspora. The associated challenges and solution approaches shall be generalised for other kinds of user-created content in federated systems.
