“As a longitudinal study, I want to be able to deduplicate the metrics/impact for our data, so that I can see the impact of our study’s date as a whole”.

NOTE: Recommendations for dynamic data will lead to studies having multiple DOIs for single datasets, and multiple DOIs for the study may be used in any one given paper. So deduplication is needed to reduce double-counting.
