FigShare Presentation at DTU
As a part of the data management work of our AIS-BDM office at DTU, we are looking into different solutions for storage, sharing and archiving of research data.
One of them is FigShare, which is offered for researchers and also as an institutional solution for the data repository.
Here is the material presented on March 14th 2016 at DTU.
