Pedro Home Page

Pedro is a subscription/notification communications system that also provides support for peer-to-peer communication. It can provide high-level communications support for agents. Pedro is based on Prolog technology - notifications are Prolog terms and subscriptions consists of a Prolog term (head) and a Prolog goal (body). A notification matches a subscription if the notification term unifies with the subscription head and the subscription body succeeds.

Peer-to-peer communication is achieved by providing a special restricted form of subscription containing an address as part of the subscription head.
