Abstract
A set of axiomatic modal propositional logics of type S4 called K″, realizing a federated information system, is described. The elements of K″, called nodes, each have their own epistemic operator, and a query algorithm giving the semantics for the multi-modal K″ is presented. Cooperation between nodes in K″ is described by means of a cooperation principle and by so-called negotiations, consisting of derivations in which some propositions originate in a different node from the one performing the derivation.
