P2P applications using the semantic information oriented network

This paper describes P2P applications using an advanced P2P platform called SIONet. Based on its metadata-based routing and easy communication creation capabilities, various kinds of P2P applications can be constructed. Effective discovery, P2P content delivery with digital rights management, semi-active information exchanging community, and P2P ad hoc community are constructed. These are expected to be bases for next generation ubiquitous applications.
