8. Service Viewpoint

8.1. Overview

The service viewpoint of the SensorSA specifies the interface and service types that aim at improving the syntactic and semantic interoperability between services, source systems and applications. These interface and service types principally cover all of the functional domains as illustrated in Figure 6-1 and described in section 6.2. The services are described according to the service description framework of the RM-OA, 2007 and are structured as follows: - Section 8.2 focuses on the services of the acquisition domain on the basis of the services of the OGC Sensor Web Enablement initiative. - Section 8.3 focuses on the services that support the abstract access control pattern as introduced in section 6.8.2. - Section 8.4 provides the descriptions of the remaining architecture services of the mediation, processing and application domain. Note: Services of the sensor domain are out of scope of the current version of the SensorSA. The user domain is not specified on an abstract level in the SensorSA. Instead, implementations of user-oriented services in a Web-based environment may be found in the Service Support Environment ESA SSE, 2007.
