Note. Annotations are metadata associated with items on a given example at a certain time. There is no need to have a stored value at that time, 3.1.2 BoundingValue The value associated with the start and end time. Note. When reading from the historical database, the boundary value is the value related to the start and end time of the specified processing interval. When requesting the original When starting data, the client may need boundary values to determine the start and end values. If the original data exists at the beginning or end point, then even if the data It is part of the data request and can still be considered as a boundary value. If there is no original data at the start or end point, then the server will determine the boundary Value, which requires data from data points outside the required range, see 4.4. ......
