  We introduce a formalism to couple integrity constraints over general-purpose
knowledge bases with actions that can be executed to restore consistency. This
formalism generalizes active integrity constraints over databases. In the more
general setting of multi-context systems, adding repair suggestions to
integrity constraints allows defining simple iterative algorithms to find all
possible grounded repairs - repairs for the global system that follow the
suggestions given by the actions in the individual rules. We apply our
methodology to ontologies, and show that it can express most relevant types of
integrity constraints in this domain.
