A sheaf associates information to the open sets of X. This information can be phrased abstractly by letting O(X) be the category whose objects are the open subsets U of X and whose morphisms are the inclusion maps V → U of open sets U and V of X. We will call such maps open immersions, just as in the context of schemes.
