This element contains information about the aggregation process.<br /></p><p><br /></p><p>Its attributes are<br /></p><p>- <b>frequency</b>:    describes the measuring frequency of the intermediate values,<br /></p><p>        and are, in fact, stored as a duration.<br /></p><p>        For example a value of 1min means that an intermediate value is measured every minute. <br /></p><p>        Typically, these values are not stored and are only used to build an aggregated value or to<br /></p><p>        determine the maximum / minimum of a longer time span (e.g. a whole day).<br /></p><p><br /></p><p>- <b>interval</b>:    aggregation interval, e.g. the period for which the value is representative<br /></p><p><br /></p><p>- <b>offset</b>:        describes the time offset<br /></p><p>        E.g., in case of a 30min interval with a 5min offset,<br /></p><p>        the interval starts 5min and 35min after the full hour, etc..<br /></p><p><br /></p><p>- <b>level:        </b>may be, for example, the value or delta-value, which (when exceeded/underrun)<br /></p><p>        triggers a measurement in event-based time series.<br /></p>
