From 03rd March 2014 all authors who submit to a PLOS journal will be asked to provide a Data Availability Statement, describing where and how others can access each dataset that underlies the findings. The Data Availability Statement will be published on the first page of each article.
"...authors must make all data publicly available, without restriction, immediately upon publication of the article. "
Further guidance is provided on their blog. Information is provided on:
- What they mean by data
- What they mean by publicly available
- Allowable exceptions to data sharing
