Appendix II

An example of information flows

(This appendix does not form an integral part of this Recommendation.)

This appendix describes information flows for providing WoT services. The information flow
shows an example of a use case of how to provide a WoT service or how to access things.

II.1 Information flow between web client and things
Figure II.1 shows one of the information flows relating to using WoT services. In this case, the web
client wants to get a WoT service which consists of several kinds of things. At first, the web client
sends a request for the WoT service to the WoT service functions using web technology (e.g.,
HTTP). And then the WoT service functions can access things through interworking with WoT
broker functions. The detailed operation with information flow is followed as below.
