Q: What are the rules for reusing data sets accompanying publications?

Detailed Question -

Once data sets have been made publicly available along with a publication (as required nowadays by several publishers), what are you expected to do if you intend to reuse them for a purpose other than what was done by the authors? Do you need to inform the authors of what you intend to do beforehand? Or it is enough to refer to the original work in the bibliography?

1 Answer to this question

The idea behind publishers' data sharing mandates is to make data open for reuse. In most cases, data sets accompanying publications are freely available for reuse by other researchers, of course, with proper citation and attribution. Generally speaking, you are not required to take the permission of the authors, unless specified in the paper or the journal. However, you should use complete data citations in the style that is appropriate to your field. This usually includes the name of the author, publication date, title, publisher, and digital object identifier (DOI).

It is recommended that you check the style guide that is followed in your field while citing a data set. Here is an example of data citation formats used in different style manuals:

APA: Cool, H. E. M., & Bell, M. (2011). Excavations at St Peter’s Church, Barton-upon-Humber [Data set]. doi:10.5284/1000389

Chicago: (Footnote) H. E. M. Cool and Mark Bell, Excavations at St Peter’s Church, Barton-upon-Humber (accessed May 1, 2011), doi:10.5284/1000389.

(Bibliography) Cool, H. E. M., and Mark Bell. Excavations at St Peter’s Church, Barton-upon-Humber (accessed May 1, 2011).doi:10.5284/1000389.

MLA: Cool, H. E. M., and Mark Bell. “Excavations at St Peter’s Church, Barton-upon-Humber.” Archaeology Data Service, 2001. Web. 1 May 2011.<http://dx.doi.org/10.5284/1000389>.

Oxford: Cool, H. E. M. and Bell, M. (2011), Excavations at St Peter’s Church, Barton-upon-Humber [dataset] (York: Archaeology Data Service), doi:10.5284/1000389

Similarly, if you are using a data set from a repository such as Dryad, you should follow the data citation format suggested by the repository. Here is an example of the data citation format suggested by Dryad:

Kingsolver JG, Hoekstra HE, Hoekstra JM, Berrigan D, Vignieri SN, Hill CE, Hoang A, Gibert P, Beerli P (2001) Data from: The strength of phenotypic selection in natural populations. Dryad Digital Repository.doi:10.5061/dryad.166
