Stream (Core Services)
A stream is defined as a collection of time series data. Currently, only the following resources represent time series data and are considered as streams:
Attribute with a data reference
Note that an attribute without a data reference is not considered as a stream.
A stream set is defined as a collection of streams. Streams inside a stream set can be independent, or share the same base element (e.g. element or event frame) or parent (e.g. parent attribute).
