Tutorial 3: models and languages for describing and discovering eservices
Fabio Casati, Ming-Chien Shan · International Semantic Web Conference · 2001
E-services are business functions made available via the Internet by service providers, and accessible by clients that could be human users or software applications. The main benefit of the e-services environment is that clients are able to dynamically discover the available e-service that best meets their needs, to examine its properties and capabilities, and to determine if and how to access it. However, in order to deliver e-services to clients, service providers are faced with several challenges. In particular, they need to describe e-services in a way that is accessible and understandable by the clients and to advertise them in web directories, so that they can be discovered by brokers as well as by end-users. In this tutorial we discuss the main requirements for models and languages for service description and discovery, and we present relevant approaches proposed by standardization consortia.
