Figure \ref{692056} shows a large number of unresolvable doi.org links in submitted DASs. This may be disappointing, but is also to be expected. The analysis here is of DASs in submitted manuscripts, which we expect to contain errors. Publishers query and correct errors and oversights in submitted manuscripts, including in DASs and citations, through the publishing process. This improves submitted manuscripts in ways that make significant impact for authors and readers. Providing clear information when it is needed, to support better data citation practices by research authors, is important \cite{mrqa8p}. It is also important to note that the large proportion of unresolvable doi.org links in our data set may have implications; the observations we make below may change if we were able to resolve those unresolvable doi.org links and assign them to domains and repositories.
