The primary reasons behind data sharing, its wider benefits and how to cope with the realities of commercial data

Data availability expectations have changed over the years in scientific publishing, nowhere more so than in the field of genomics. This field has spearheaded openness and transparency via public and structured deposition of data. BMC Genomics strongly encourages deposition and unrestricted availability of all primary data underlying research studies both as a way of ensuring reproducibility and standardisation, but also as part of overall community-driven expectation on data deposition and sharing. With funders and publishers moving towards more explicit mandates (regarding data availability), we examined the current barriers to unrestricted availability of data and explored different scenarios in which commercial agreements might run contrary to scientific convention and data sharing policies. In this editorial, Ross Tellam (CSIRO, Australia), Paul Rushton (Texas A&M AgriLife Research) and Peter Schuerman (University of California, Merced), give their views on the importance of data sharing and examine the current challenges in research fields like crop and livestock genomics, where often it is necessary to integrate the interests of academic and commercial stakeholders. We discuss the current approaches, highlight the importance of community-driven standards, and propose ways forward.
