Rationale
“The data deluge has arrived.[…] If the rewards of the
data deluge are to be reaped, then researchers who
produce those data must share them”
Borgman, 2012
Peng, 2011
Rationale
“The ‘dirty little secret’ behind the promotion of data
sharing is that not much sharing may be taking
place”
Borgman, 2012
“The lack of recognition incentives is regarded as a
crucial and unresolved obstacle to establishing a
data sharing culture”
Piwowar et al., 2008
Data and citations
“A consistent, rigorous approach to data citation is
lacking”
Parsons et al., 2010
What do we cite?
Data papers <- Scientific Data
Data sets <- Data Citation Index
Original study <- Piwowar et al.

Discussion
I. High rate of uncitedness (88%)
II. Biased towards the Hard Sciences
III. Data sets vs. Data studies (Two Cultures?)
IV. Too soon or too presumptious?
