An OSGi-based semantic service-oriented device architecture

摘要

The implementation of service-oriented device architectures (SODA) suffers from restrictions that are imposed by the use of existing syntactic technologies. Related problems include data and message-level heterogeneities among interoperating services, insufficient search and discovery of exposed services and inadequate web process composition. In this paper we propose an approach for introducing semantics in a SODA environment. Specifically we examine the introduction of data, functional and behavioural semantics and the role they play in a semantically-enabled SODA (SeSODA) pervasive environment. We put special emphasis in data semantics. We present the architecture of an OSGi-based SeSODA implementation, analyse the most critical components of this architecture and discuss implementation issues. © Springer-Verlag Berlin Heidelberg 2007.
