While several techniques have been introduced for specifying and acquiring
context and quality information associated with Web services, they consider
such information representing the whole Web services. However, accessing
to context and quality of data resources provided byWeb services is crucial. This
is particularly relevant for data-intensive Web services of which the context and
quality of data resources will strongly impact on the service development and
composition. In this paper we contribute an analysis of relationships among context,
quality, and relevance, as well as their impact on the design and composition
of Web services, in particular at the data resource level. Then, we propose several
techniques to incorporate context and quality descriptions into REST APIs
and RESTful services publishing. By implementing these features, RESTfulWeb
services could allow the consumer to specify and query context and quality information
associated with services and data resources, thus fostering the provision
of high relevant data resources.
