Google is working on the Knowledge graph, collecting all the worlds information in one easy accesable database that can provide answers to all questions. Facebook on the other hand is building the Social Graph, a data string with interconnected identities and social interactions. The internet of things is all about building the physical graph, a data string with interconnected objects and machine2machine- and human-computer interactions.
First question: who will own it? It seems plausible to me that we will have more than one internet of things. An ioT by Apple with Apple products, one from Google etc. If appstores are any hint there are ‘walled gardens’ coming to the internet of things. More on this in other articles I am currently working on.
For now a easier question: what will feed the physical graph with data? A lot of devices. Check out this infographic providing a timeline of devices coming online all the way back to the sixties. But it’s not all about the devices: it’s also about our interactions with the data and the interactions between the devices itself. Those three pillars will form the physical graph (click on the image to enlarge).
