2. Research Data Sharing Policy at Wiley

At Wiley, we are making open research not just the future of research and research communication, but the here and now. We have four policy-level requirements for data sharing, adopted across our portfolio of journals [14].
  1. “Encourages data sharing” is our entry-level policy to encourage data sharing. It enables journals serving researchers in communities where data sharing is not common to start their journey towards data sharing. There are no enforced requirements.
  2. “Expects data sharing” is a policy for journals that require from every author a data availability statement to confirm presences or absence of shared data, and a data citation. It is equivalent to the Transparency and Openness Promotion (TOP) level 1 guidelines [15].
  3. “Mandates data sharing” is a policy for journals that require a data availability statement, a data citation, and sharing of data (it is equivalent to TOP level 2 [15]).
  4. “Mandates data sharing and peer reviews data” is a policy for journals that take the additional step of peer reviewing data (it is the equivalent to TOP level 3 [15]).
Of course, we recognize that the process of adopting open research practices can be challenging and requires cultural change as emphasized by Henriikka Mustajoki (Head of Development, Federation of Finnish Learned Societies) [16]. Our four policy levels give flexibility so that journals can adopt policies that are right for their research communities.
Tiered policies like these adopted by major publishers and journals enable journals to adapt to the communities they serve [17]. The Wiley data sharing policies are shown in Table 2, which maps each against the Transparency Openness Promotion (TOP) guidelines [15] that are used by publishers and funders to increase transparency.
