Abstract
Web services constitute a promising technology to support autonomic computing. Automatic discovery of new services, their composition and binding based on Quality of Service (QoS) are just some of the most promising features that can be provided using web services. In other words, a service oriented system is able to automatically discover, bind, and use, at run time, the services that, among those available, offer a given piece of functionality with a QoS compatible with the system non-functional requirements.This paper describes our work-in-progress related to the development of an electronic marketplace, named C 3 (Creation, Certification and Classification of Services) to enable the publication, semantic discovery, service buying, SLA negotiation and QoS-aware composition and replanning. The marketplace is mainly targeted to corporate intranets, although its technologies and approaches can be easily exported to a wider scenario.
