As an indispensable component in Service-Oriented Ar chitecture (abbreviated as SOA), UDDI registry provides universal description, discovery and integration of services through UDDI API. These services may include Web Ser vices or Grid Services. However current UDDI lacks suf ficient metadata to describe service capability and relation ship which inevitably brings difficulty to discover the most appropriate service or related services from massive exist ing services. This paper briefly introduces an enhanced UDDI which is supposed to easy services or their relation ship discovery by adding new metadata and APIs. Finally this paper draws out a framework for discovering and in voking services dynamically.
