  10. 10. Steps of IoT Data Modeling 1.What is the THING in my application? 2.What phenomena (i.e., OBSERVED-PROPERTY) are my THING observing? 3.What SENSORs am I using to collect observations? 4.What is the target (i.e., FEATURE-OF-INTEREST) of my observations?
  11. 11. What is a Thing? • A thing is an object of the physical world (physical things) or the information world (virtual things) that is capable of being identified and integrated into communication networks. (ITU-T Y.2060) 11
