A P2P Based Personal Digital Library for Community

The function of digital library is not limited to information management now, but also has more relationship with community. P2P networks are highly scalable platforms, which should be suitable for personal digital library, but the contradiction between efficiency and autonomy holds back their progress in applying them to DL. In this paper, we propose an autonomous flexible content addressable network (Flexible CAN), in which nodes can change their position freel. Flexible CAN has the advantages of both efficiency and autonomy. It can be used not only for information managing and retrieving, but also autonomic detect group of users with the same interest. Thus the group becomes a community, and users can share their resources and experiences conveniently.
