When using CoAP, you can choose between a number of different methods for obtaining TDs, all of which use IP multicast (both IPv4 and IPv6). The discovery node can obtain TDs from the local network (using CoAP) or from a MQTT broker and save them either in the context or in the original message object that was passed to the node. It supports the URL schemes http(s) and coap(s). The fetch node can retrieve TDs from URLs which can either be specified in the node itself or as a message property (using the field msg.tdUrl). It provides a wot-discovery node that can be used for discovering and storing WoT Thing Descriptions (TDs) as well as a wot-scripting node that serves as an interface to node-wot for triggering interaction affordances.Īs a latest addition, a wot-fetch node provides a way to retrieve TDs directly from URLs using HTTP(S) or CoAP(S).
