Pick one Eurostat series from the dataset namq_10_a10_e.
When you look at the SDMX API for this series (http://widukind-api.cepremap.org/api/v1/sdmx/EUROSTAT/data/namq_10_a10_e/Q.THS-HW.TOTAL.SCA.EMP-DC.EA19), you can see the series ID : Q.THS_HW.TOTAL.SCA.EMP_DC.EA19, which doesn’t contain the name of the dataset.
I think it could be useful to have it in the ID. It is even mandatory if we want unique IDs, because today it is possible to have the same ID in different datasets.
