TR-0045 Use Case

This clause briefly describes a use case from the perspective of services provided by the oneM2M platform. The physical device components will be introduced in this clause.

In the use case, different sensor measure temperature information, but the temperature relates to different aspects, i.e. indoor, outdoor and fridge temperature and the temperature is measured in different scales. Simply discovering temperature does not solve the problem as the temperatures relate to different aspects. Through semantic annotation and semantic discovery of resources the resources that are relevant in a particular use case can be found.

An overview of the use case is shown in figure below. The main components include:

  • The temperature sensors are connected to a server.

  • The server provides a set of services to enable the applications on smartphone #1 to discover and retrieve the relevant temperature information.

  • The server provides a set of services to enable the applications on smartphone #2 to manage and semantically annotate the services providing temperature information.
