For the vision of ubiquitous, easily invokable Web services to become a reality, it will be necessary for service requesters to compare the quality-of-service (QoS) aspects of various services. So standardized QoS information must become a part of the service discovery process. This article surveys the current research on QoS and service discovery, including ontologies such as OWL-S and DAML-S. The authors then propose their own ontology, DAML-QoS, which provides detailed QoS information in a DAML format.
