A couple of weeks ago the British Ecology Society Journals published a virtual issue for Open Access Week looking at the most downloaded data sets in Dryad associated with papers on the journals. At Journal of Animal Ecology we encourage authors to use the most appropriate archive for their data and in JAE we’ve seen a variety of repositories used alongside Dryad. For Open Access Week 2016 I looked at the different repositories used by authors in the five BES journals, and in the Journal of Animal Ecology Editorial at the start of this year we looked at this in more detail. The BES journals are integrated with Dryad and cover arching costs for papers published in the journals, and this is by far the most commonly used archive with data from 65% of papers in JAE stored there. After this, the most used repositories are figshare (5%), NERC Data Centres (2%) and Movebank (almost 2%). To complete the picture I thought I’d take a look at the most downloaded data sets in these repositories to complement the list of the most downloaded data sets in Dryad associated with JAE papers. I also spoke to Kathryn Harrison from the NERC Environmental Information Data Centre for her views on best practice for data archiving and reuse. Kathryn also took part in our panel discussion on the future of data archiving in 2015, alongside Mark Thorley, James Pearce-Higgins, Liz Ferguson, Natalie Cooper and chaired by Chuck Fox. The recording of the discussion is available here.
For all the data sets I’ve provided the number of downloads as it is a useful and relevant metric and often the only metric that many repositories have, however, downloads doesn’t necessarily mean a dataset has been reused or cited. Furthermore download data can be affected by crawlers and distinguishing between genuine downloads versus crawlers can be a challenge for repository curators. Demonstrating that a data set has been reused is key to ensuring that people who create publicly available data sets receive credit for it. However, achieving this is not straightforward. Citations of data sets would be useful but this isn’t yet readily available. To compound this problem Kathryn Harrison comments that often authors don’t include information on a data set used in a paper in a format that allows it to be picked up by web of science or other indexing services.
The overall goal from Kathryn’s perspective is to “improve the numbers of datasets cited correctly and display proper citation metrics for each dataset” by doing so, Kathryn believes we’d “get much better linking up between journal papers, the datasets they are based on and the impact certain datasets are having in a particular field of science and also greater reproducibility and transparency”, this is a goal that we very much support.
At the BES we’ve tried to address this by ensuring that data sets are properly cited in the reference list of all papers published in the journals and we now enable authors to include all sources used in a meta-analysis (or similar) in the published paper under a ‘Data sources’ section so that they can be fully indexed and their authors are given proper citation credit.
Going forward, at JAE we continue to encourage authors use the most appropriate repository for their data so that it is most usable and discoverable to the members of the ecological community likely to access their data, and to remind authors to properly cite all data sets in their paper.
I would like to thank Kathryn Harrison for providing the download data for data sets in the NERC data centres and Sarah Davidson for providing download data for Movebank data sets.
