Matchmaker is implemented as an extension of the jUDDI which is an open source Java implementation of UDDI. You do not need to install jUDDI since it is included in the default installation package of the matchmaker starting from version 1.3. The web interface provides an intitutive interface for users to interact with the OWL-S/UDDI matchmaker. The interface allows users to build OWL-S descriptions which can be submitted as advertisement or query. The mapping between OWL-S to UDDI is performed performed at users browser using javascript.
