Managing your relations in web 2.0

This work deals with the synchronisation
of social network services. This type of internet
application enjoys great popularity which results
in new challenges for identity and relation
management. On one side the user has to manage
different identities and on the other side a
friendslist per social network service. From this
efforts arose to make data portable and
reusable for example in order to avoid re-declaring
friends on every site. To accomplish this goal
numerous projects and technologies have been
developed, which already provide partial solutions
for this problem. The basic conceptual question
however how to deal with the problem generally is
still open. Moreover some of the techniques are only
suitable for special use cases or else not ready for
a professional use. In this thesis some of the
existing standards shall be used to tie them together
to one total system. This system consists out of a
central identity provider, which functions as a
central storage for the users contact data. By
utilising interfaces this contact data
can be exchanged with the social network service and
by that improves the relation management for the
users.
