Abstract
The implementation of service-oriented architectures is mostly driven by the motivation to create a flexible and maintainable IT. Whether this goal can be achieved or not strongly depends on the design quality of the services. For that reason, the services within a service-oriented architecture have to be created with care. In the past, several quality attributes and quality indicators were identified that provide information about the design quality of a service. These quality indicators were described with focus on method-driven services based on SOAP. However, today, services are often designed in a resource-oriented way using REST or similar approaches to enable technology-independent interactions. For that reason, this chapter maps the existing quality attributes and quality indicators onto resource-oriented web services. As result, architects and developers get a toolset to design resource-oriented web services in a service-oriented architecture systematically in a quality-oriented manner. The quality indicators are illustrated by means of a resource-oriented web service in the context of a service-oriented SmartCampus system developed at the Karlsruhe Institute of Technology. The scenario shows that the application of the quality indicators limits the design scope and accelerates making design decisions.
