Electronic inter-organizational relationships are governed by contracts regulating their interaction, therefore it is necessary to run-time monitor the contracts, as to guarantee their fulfillment. The present work shows how to obtain a run-time monitor for contracts written in \(\mathcal {CL}\), a formal specification language which allows to write conditional obligations, permissions, and prohibitions over actions. The trace semantics of \(\mathcal {CL}\) formalizes the notion of a trace fulfills a contract. We show how to obtain, for a given contract, an alternating Büchi automaton which accepts exactly the traces that fulfill the contract. This automaton is the basis for obtaining a finite state machine which acts as a run-time monitor for \(\mathcal {CL}\) contracts.
