define Package/node-mozilla-iot-gateway/description
  Build Your Own Web of Things Gateway. The "Web of Things" (WoT) is the
  idea of taking the lessons learned from the World Wide Web and applying
  them to IoT. It's about creating a decentralized Internet of Things by
  giving Things URLs on the web to make them linkable and discoverable,
  and defining a standard data model and APIs to make them interoperable.
