TL;DR: This paper addresses the problems related to the data format and the architectural style followed by the implementation of the SWE services and proposes the adoption of the lightweight Representational State Transfer (REST) web services concept and the usage of JavaScript Object Notation (JSON) format as an alternative to the verbose XML one for the exchanged messages.

Abstract: Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not straightforward. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. The concept of the Sensor Web reflects such a kind of infrastructure for automatically discovering and accessing appropriate information from heterogeneous sensor devices over the Internet. In this context, the Open Geospatial Consortium (OGC) established the Sensor Web Enablement (SWE) initiative that specifies standard interfaces and encodings to remotely access, encode and exchange the sensed data. However, SWE standards have several gaps that limitate its capabilities to achieve the sensor Web desires. In this paper, we address the problems related to the data format and the architectural style followed by the implementation of the SWE services. Indeed, we propose the adoption of the lightweight Representational State Transfer (REST) web services concept and the usage of JavaScript Object Notation (JSON) format as an alternative to the verbose XML one for the exchanged messages.

- 21 Apr 2008
TL;DR: This paper objectify the WS-* vs. REST debate by giving a quantitative technical comparison based on architectural principles and decisions and shows that the two approaches differ in the number of architectural decisions that must be made and in theNumber of available alternatives.

RESTful web services: principles, patterns, emerging technologies

- 26 Apr 2010
TL;DR: This tutorial gives an introduction to the REST architectural style as the foundation for RESTful Web services and argues that it does have distinct advantages for loosely coupled services and massive scale, and that any SOA approach already has to be specifically RESTful on the business level to yield meaningful input for IT architecture design.
