While several techniques have been introduced for specifying and ac- quiring context and quality information associated with Web services, they consider such information representing the whole Web services. However, accessing to context and quality of resources provided by Web services is crucial. This is particularly relevant for data-intensive Web services of which the context and quality of resources will strongly impact on the service development and composition. In this work, we focus on studying relationships among context, quality, and relevance, as well as their impact on the design and composition of Web services, in particular for data-intensive services. Then, we will focus on the development of techniques to incorporate context and quality descriptions into service APIs and RE services publishing.

- Scenarios: Search result without context/quality parameters, Search result with context/quality parameters
- For the demonstration purpose, we provided customized quality and context models based on the work on data concerns for data-as-a-service
- Examples of context model: XML Schema, JSON
- Examples of quality model: XML Schema, JSON
- Example of WADL with context and quality of data specification
