WoT — Web of Things Connector
Web of Things connector — exposes Things from the W3C WoT initiative over OPC UA. NodeIds only; the registrar is named WotConRegistrar.
OPC UA companion specification mapping the W3C Web of Things standard onto OPC UA. The "WotCon" name reflects that the spec is a connector — it lets a WoT Thing's Thing Description be addressed and manipulated through OPC UA.

None — WoT is a root spec.
What you typically use
WoTNodeIds::* for the spec's type-definition NodeIds. The
typical interaction is: a WoT gateway exposes Things over OPC
UA; your application browses the WoT-defined structure to discover
exposed Properties, Actions, Events; reads / calls each via the
standard OPC UA primitives.
