In this chapter, you’ve been shown the basic principles of how to create a controller that dynamically finds, connects to, and interacts with devices in its vicinity on the internet. You’ve been introduced to the fundamentals of discovery on the internet, as well as the basic principles of Thing Registries and how these can be used to interconnect entities on the internet. You have learned the difference between conceptual and network identities, and how these can be paired using an ownership claim procedure. You’ve also learned how XMPP helps realize discovery and interaction between devices, how to register self-owner devices, update metadata about the device, and search for devices in a Thing Registry. You also know how to maintain a sensor data subscription alive with a sensor and how to perform control operations on an actuator. In the next chapter, we will delve deeper into the concepts of security and interoperability between things on the internet and see how standardization...
