For infrequently updated time series, it may be appropriate to assign a new PID with every update or provide periodic “snapshots”. For frequently updated data (daily or more often), data centers will often assign a PID to the general data stream and only create a new one when there is a new version of the stream. This is discussed more in the ESIP guidelines. <a href="https://doi.org/10.6084/m9.figshare.8441816" class="">https://doi.org/10.6084/m9.figshare.8441816</a>. </div><div class=""><br class=""></div><div class="">For subsets, the RDA Dynamic Data Citation guidleines (<span style="color: rgba(0, 0, 0, 0.85); font-family: Arial;" class=""><a href="https://dx.doi.org/10.15497/RDA00016" class="">https://dx.doi.org/10.15497/RDA00016</a>) </span>recommend that one provide a PID for the overall collection and then assign a PID to any arbitrary subset as obtained through a query. So a citation of a subset would have two PIDS — one for the collection and one for the subset.</div><div class=""><br class=""></div><div class="">None of this has much to do with credit, however. For many time series the credit is the same for the collection and the granule or subset, but in some cases different individuals may be responsible for different granules within a collection and should therefore be credited accordingly. There has been a little work showing how the RDA methodology can be used to do this, but that was not the original intent of the Recommendation. </div><div class=""><br class=""></div><div class="">What we are finding as we go through this exercise, is that credit is a human concern and often requires human judgement.
