Many thanks to Hardy Schwamm, Research Data Manager from the Library, for his informative session on Figshare and Zenodo. These are both Open Repositories for sharing research data and other research outputs, such as images, software or slides.
Hardy has provided this follow up from a question during the session:
How does Figshare handle different versions of the same document? Does each version get a different DOI? This is probably easiest to demonstrate with an example. Here is a document that John Lewis at the University of Sheffield has published, discussing their RDM infrastructure options:
Lewis, John (2014): Research Data Management Technical Infrastructure: A Review of Options for Development at the University of Sheffield. figshare. http://dx.doi.org/10.6084/m9.figshare.1202230 Retrieved 09:44, Feb 13, 2015 (GMT)
He has updated this document multiple times after several people commented on this document and suggested updates and omissions.
When you visit the DOI, you are offered the most recent version, but at the bottom end of the record there are links to all of the previous versions, and each has a datestamp.
If you click through to any of the earlier versions, there is a banner above the preview highlighting that there is a more recent version of the file. Clicking on that link will take you to the latest version. Again, at the bottom of the record for the order version, there are links to any earlier versions.
Note that the DOI is the same for all versions, so in effect the DOI is for the set of versions of the file. This seems to be DataCite’s preference at present for versioned files.
We got in touch with Figshare and they commented that they would prefer for the versioning to be explicit in the DOI (e.g. 10.6084/m9.figshare.1202230.v9) but the debate around DOIs and versioning continues in the data repository world.
