Greetings from the Australian National University in Canberra, where I am attending "Powering up your 2018 (data skills) training". This is provided by Australian National Data Service (ANDS), National eResearch Collaboration Tools and Resources project (Nectar) and Research Data Services (RDS). The idea is to help those who train researchers in using data repositories.
Data repositories are used not just by researchers, but also for teaching. The Atlas of Living Australia is also used by schools.
One of the problems with data repositories of data is motivating researchers to learn to use them and use them. The researcher tends to be focused on their PhD, or project and then getting the next grant. Making their data available for others to use may not be seen as helping with this (although researchers now get some credit for publishing data).
ps: The instructor perhaps was having a dig at me just now saying "You don't want people playing with computers and not paying attention", but obviously I am. ;-)
