Web of Things

!!!

“the Web of Things reuses existing and well-known Web standards[1][2] used in the programmable Web (e.g., REST, HTTP, JSON), semantic Web (e.g., JSON-LD, Microdata, etc.), the real-time Web (e.g., Websockets) and the social Web (e.g., oauth or social networks).” !

Near-term Solution Milestones

WoT.City company starts wotcity.com project at May, 2015. It is a SaaS cloud platform which enables the connectivity of physical devices through the web. WoT.City is including and has an implementation of W3C Web of Things Framework. WoT.City has a combined HTTP and WebSocket server. Please visit https://wotcity.com

WoT.City has been developing the Web of Things framework. The software is an open source project. We would like to work with open source community. The development work is also including the principles of W3C Web of Things Framework.
