In this paper, the finite subspaces of orderings of the ring of regular functions on an algebraic set V are compared with those of the ring of analytic function germs at a point of V. Necessary and sufficient conditions for subspaces to be isomorphic are given, both from a purely algebraic and from a more geometric point of view.
