The access layer in the WoT is built around two core patterns: Firstly, all things should be exposing their services through a RESTful API (either directly or through gateway).[1] REST is an architectural style at the root of the programmable Web thanks to its implementation in HTTP 1.1. As a consequence, if things offer RESTful APIs over HTTP, they get a URL and become seamlessly integrated to the World Wide Web and its tools such as browsers, hyperlinked HTML pages and JavaScript applications.[2]
