WoT Discovery

The WoT Discovery specification defines a mechanism to provide access to WoT Thing Descriptions in both local and global contexts. It uses a two-phase approach to take advantage of existing discovery mechanisms for "first contact" but provides for authenticated web services to actually provide metadata in order to support security and privacy goals. WoT Thing Descriptions can be retrieved from services running either on a Thing itself (that is, directly from self-describing objects), or from a directory service that provides a searchable database of WoT Thing Descriptions.
