6 Overview of the WoT service

The web is used as a global standard platform to deliver services to an end user and applications to
intercommunicate with each other over a network. [ITU-T Y.4400] describes that the web has
program language independent properties, uses message driven communications and easily bounds
to different transport protocols. Web technology allows the exposure of physical devices as well as
several kinds of content as web resources such as URI and HTTP. Therefore, users and service
developers can interact with the devices using web interfaces. The WoT can provide capabilities
such as device reusability, portability across several heterogeneous networks and accessibility based
on web standards technologies.
Figure 1 shows a general concept of the WoT service. The physical devices as well as content are
integrated into the web and are viewed as the sort of services provided by the web environment. In
addition, each service has a mash-up capability to create a new service by composition of the
existing services in the web environments. According to [ITU-T Y.4400], the web technologies can
support to create applications of networked devices and services.
