I think I understand this, but I don’t understand where WoT fits in. As far as I can tell, it’s about embedded programming. The CHIRMEN board doesn’t seem to have a network connection or a display connection. It’s an embedded linux computer with GPIOs that runs a browser environment as an embedded programming environment. A developer writes html with embedded javascript and local GPIO and I2C javascript libraries in order to program hardware sensors and actuators which are directly connected to the board’s I/O pins. So basically a developer can pretend they're programming in a browser using HTML and javascript and tags and stuff when programming an embedded linux based controller. I guess you write the code using your favorite web design tool and then download it to the board, where it executes and blinks the LED. Am I missing something important?
