Windowing is applicable to time series data. It takes two BaseAttributes from the input Concept; one of contains time stamps, the other values. In the output Concept each row gives a time window; there will be two time stamp BaseAttributes which give the beginning and the end of each time window. Further, there will be as many value attributes as specified by the WindowSize; they contain the values for each window. Distance gives the distance between windows in terms of number of time stamps.
While TimeBaseAttrib and ValueBaseAttrib are BaseAttributes
that belong to TheInputConcept, OutputTimeStartBA, OutputTimeEndBA
and the WindowedValuesBAs belong to TheOutputConcept.
