The `ic-data:Datapoint` is an atomic piece of information about a certain observable quantity in nature that can contain a numerical value and a corresponding unit of measure. An `ic-data:TimeSeries` is related to the `ic-data:Datapoint` class via the `ic-data:hasDatapoint` (0..N) property and is defined as an ordered sequence of data-points of a quantity that is observed at spaced (not necessarily equally spaced) time intervals.

The `ic-data:Datapoint` is defined as a subclass of `saref:Measurement` and, as such, inherits the `saref:hasValue` and `saref:hasTimestamp` properties. Therefore, if the combination of a value and timestamp is sufficient to represent a datapoint, then the SAREF concepts for measurement can be directly reused. However, we noticed that often, especially when representing timeseries of datapoints in a forecast, a number of additional properties are needed. Therefore we extended SAREF by assigning to the `ic-data:Datapoint` and the `ic-data:TimeSeries` the following properties:
