Fig. 6 The Google Fit Service representation
Sensor, to describe all possible sensors, not considering their specific functionality.
(2) Parameter, which is subclassed by InputParameter and OutputParameter. Such
classes represent input and output of the sensor. (3) Method, representing the particular function that can be called on the sensors.
The aforementioned classes are connected via specific object properties:
(1) hasElement/ElementOf are converse properties that connect complex and simple
parameters where structured ones exist. (2) hasParameters is used to link parameters to specific methods (3) Exposed is used to declare that a sensor has a specific
functionality To express equivalences between methods, sensors and parameters no
further elements are needed, as OWL provides native structures to identify equal concepts. Figure 6 provides a simple example of the API graph produced after analyzing
the REST calls of the Google Fit Service.
