In this paper we introduce the notion of a partial action of a groupoid on a
ring as well as we give a criteria for the existence of a globalization of it.
We construct a Morita context associated to a globalizable partial groupoid
action and we introduce the notion of a partial Galois extension, which is
related to the strictness of this context.
