The CommunityMashup is an open-source integration solution for data from social services. It unifies and interconnects the data from different sources. This includes e. g. social networking services like facebook, microblogging services like twitter or fotosharing services like flickr but also more specific services like the reference management service and scientific social network Mendeley. In the mind of the “social web” the aggregation and filtering processes are executed with an person-centric focus. The CommunityMashup provides interfaces and framework components to easily integrate social data in concrete application scenarios.
