 <p>Although any metadata element can be used for subsetting, the most frequent cases concern the spatial and temporal dimensions. Re-using the example of budget data, the dataset can be split not only by year, but also by country / region. Other examples concerns child datasets using different temporal / spatial resolution, unit of measurement, or reference system.</p>
