The growing demand for the discovery of geo web services as parts of service chains necessitates semantic matchmaking between service descriptions. In this paper we propose a method for describing and matching services based on a geo location ontology and we demonstrate its power and its limitations with a simple user scenario. In a test environment using Protege and the Racer ontology reasoner we show some powerful constructs of Description Logics that allow us to distinguish different types of matches. We underline the importance of matching atomic concept conditions versus aggregated conditions. The use of OWL and OWL enabled tools prove to facilitate a powerful matchmaking environment.
