Peer to Peer systems are attracting increasing attention as an efficient means of sharing data among large, diverse and dynamic sets of users. Self-Peer focuses
on improving performance and quality of services that peer to peer systems offer. To this end, our goal is to organize peers according to their content and the
query workload of the system. In particular, we aim at self-organizing peers according to the set of queries that they can answer. In a nutshell, the objectives of
the project are the following:

· To self-organize peers that store XML documents, using clustering techniques.

· To self-organize peers that store database relations, using small-world networks.
