SANY D2.3.4 Specification of the Sensor Service Architecture V3 Doc.V3.1 Copyright © 2007-2009 SANY Consortium Page 14 of 233 The objective of the SensorSA is to motivate and specify the basic design decisions derived from user requirements and generic architectural principles. It provides the basic concepts and their interrelationships conceptual models and abstract specifications. By abstract it is meant that the specification is independent of the specifics of a particular service platform. Such an abstract specification comprises service specifications, information models and interaction patterns between the major architectural components. The specification of the SensorSA is structured according to the viewpoints of the Reference Model for Open Distributed Processing RM-ODP as defined in ISOIEC 10746- 1:1998 E. The RM-ODP viewpoints are interpreted in the context of a service-oriented architecture SOA in analogy to the interpretation of the RM-ODP in the Reference Model for the ORCHESTRA Architecture RM-OA, 2007. After the illustration of the architectural design process in section 3, the specification of the business context and related requirements are described in section 4 , “Enterprise Viewpoint”. Section 5 provides the specification of the “Sensor Model” used in the SensorSA. Further major concepts of the SensorSA are presented in section 6, followed by the core conceptual specification of the SensorSA, the specification of the Service and Information Viewpoints. Technological choices such as requirements and constraints about underlying Web service platforms are covered in the Technology Viewpoint in section 9. Engineering guidelines and recommendation how to use and compose the service and information models are covered in the Engineering Viewpoint in section 10. Note 1: If concepts and models of the RM-OA are re-used without change, they are just referenced, sometimes accompanied by a short summary in order to enable a self-contained specification of the SANY Architecture. In cases where RM-OA concepts and models have been refined and even replaced for SANY purposes, they are specified in the present document, but using the style and the templates of the RM-OA. This approach ensures consistent editorial maintenance and review of both documents. Note 2: The present version of the SensorSA continues and refines the work of the so- called ORCHESTRA Architecture Services OA Services with a focus on replacing the original Sensor Access Service as defined in the RM-OA, 2007. In a subsequent version, this architecture specification intends to provide more application-oriented services, which are referred to in the RM-OA as ORCHESTRA Thematic Services. Then, the SensorSA will also define elements of an Application Architecture.
