The problem with depositing research data only to repositories

"From the researchers’, and to some extent the funders’ perspective, as long as the data is held in a repository ‘somewhere’, the basic requirement of making their data accessible has been fulfilled.  

In addition to universities already managing their own repositories, there are numerous subject, funder and publisher repositories available. But, rather than focussing on the researcher or dataset, Jisc RDSS is responding to the increasing need of HEIs to oversee the management of all datasets produced by its academics."
