This paper describes an implementation of an Adapte r that converts XML to a Web Service Modeling Language (WSML) [1]. WSML is the l anguage used to describe Web Service Modeling Ontology (WSMO) [2] concepts, related to Semantic Web services (SWS). SWS are web services that are seman tically annotated. The semantic annotation is necessary to address various business logic in an appropriate manner, thus allowing complex business applications to be b uilt and executed. The Web Service Execution Environment (WSMX) [3] is an exec ution environment for dynamic discovery, selection, mediation and invocat i n of semantic web services. WSMX is a reference implementation for WSMO.
