Keyword(s): No keywords available.
Abstract: The purpose of this document is to contrast the different kinds of web service descriptions known as black, white, glass and grey-box views. In particular, the different assumptions underlying these views is claimed to be indicative of fundamental differences between DAML-Services (DAML-S), a DAML based Web Service Ontology, and the Web Service Modelling Framework (WSMF) that is central to the Semantic Web enabled Web Services (SWWS) project. Semantic web enabled web services are simply services with associated meta-data that helps us to understand what they do. By working with their semantics - the vocabulary is backed up by a model - the WSMF aims to support more robust web service interactions.
