I'am currently working on how to bring structure into a peer-to-peer
network using access controls. To get entrance to the network, peers have
to register at super peers. Each super peer provides its own policy, e.g.
which peer may join or not. Each policy consists of several rules. Here is
ON (Event) Enter IF
(Peer.Advertisement.Property metadata_schema="Dublin Core")
(Peer.Advertisement.Property peer_name INCLUDE "cs.tu-berlin.de")
DO (Action) Approve(Peer)
ELSE (Action) Reject(Peer)
Such rules are formulated by the super-peer administrator. Finally the
network is structured in several subject specific clusters, each one
represented by one super peer.
