Identifier of the point
Identifier of the Point (Point ID) is used to identify a Point which is defined as an elemental message channel for a specific data sequence among components in the IEEE Standard for Ubiquitous Green Community Control Network （UGCCNet） Protocol.[1][2][3][4]
Because the Point identifies a dataflow that exchanges data among components, so in order to identify the data sequence globally, each Point should have a globally unique identifier. In UGCCNet, every Point shall have a URI for its identifier for URI can enable global access (if the Point is public) to the Point.
Let X(=http://gw.foo.org/sensor1) be a Point ID. If components do not know the registry server that manages the Point ID (X), they should try to access X directly. Then, the URI can redirect to the registry server. If components already know the registry server for X, Point ID may not need to be reachable. However, in order to obtain operational consistency, the host of the URI should be the host name of the GW (because physical sensors and actuators are attached to the GW). Thus, typical URI format should be:
point ID = http://<GW host name>/<any format to identify the Point in the GW>.
This identifier of the point is based on the 973 project “Identifier-based Universal Networks”[5] with the chief scientist Hongke Zhang.
