Data dissemination in the era of “big data”

William Gibson: "Information is the currency of the future world”

Bio-IT World Asia Meeting, 7th June 2012
Is data “the new oil”?
Data Bonanza?
Data Deluge?

Incentives/creditCredit where credit is overdue:“One option would be to provide researchers who release data to public repositories with a means of accreditation.”“An ability to search the literature for all online papers that used a particular data set would enable appropriate attribution for those who share. “Nature Biotechnology 27, 579 (2009)
Prepublication data sharing (Toronto International Data Release Workshop)“Data producers benefit from creating a citable reference, as it can later be used to reflect impact of the data sets.” Nature 461, 168-170 (2009)
Datacitation: Datacite and DOIsDigital Object Identifiers (DOIs)
offer a solution
Mostly widely used identifier for scientific articles
Researchers, authors, publishers know how to use them
Put datasets on the same playing field as articles
DatasetYancheva et al (2007). Analyses on sediment of Lake Maar. PANGAEA.doi:10.1594/PANGAEA.587840
“increase acceptance of research data as legitimate, citable contributions to the scholarly record”.
Aims to:
“data generated in the course of research are just as valuable to the ongoing academic discourse as papers and monographs”.
Datacitation: Datacite and DOIsCentral metadata repository:
• >1 million entries to date
• Stability
• Data discoverability
• Open & harvestable
• Potential to track & credit use
www.gigasciencejournal.com
Data publishing/DOINew journal format combines standard manuscript publication with an extensive database to host all associated data, and integrated tools. Data hosting will follow standard funding agency and community guidelines.DOI assignment available for submitted data to allow ease of finding and citing datasets, as well as for citation tracking.

Final step: open licensing
To maximize its utility to the research community and aid those fighting the current epidemic, genomic data is released here into the public domain under a CC0 license. Until the publication of research papers on the assembly and whole-genome analysis of this isolate we would ask you to cite this dataset as:
Li, D; Xi, F; Zhao, M; Liang, Y; Chen, W; Cao, S; Xu, R; Wang, G; Wang, J; Zhang, Z; Li, Y; Cui, Y; Chang, C; Cui, C; Luo, Y; Qin, J; Li, S; Li, J; Peng, Y; Pu, F; Sun, Y; Chen,Y; Zong, Y; Ma, X; Yang, X; Cen, Z; Zhao, X; Chen, F; Yin, X; Song,Y ; Rohde, H; Li, Y; Wang, J; Wang, J and the Escherichia coli O104:H4 TY-2482 isolate genome sequencing consortium (2011) Genomic data from Escherichia coli O104:H4 isolate TY-2482. BGI Shenzhen. doi:10.5524/100001 http://dx.doi.org/10.5524/100001
Our first DOI:
To the extent possible under law, BGI Shenzhen has waived all copyright and related or neighboring rights to Genomic Data from the 2011 E. coli outbreak. This work is published from: China.
“The way that the genetic data of the 2011 E. coli strain were disseminated globally suggests a more effective approach for tackling public health problems. Both groups put their sequencing data on the Internet, so scientists the world over could immediately begin their own analysis of the bug's makeup. BGI scientists also are using Twitter to communicate their latest findings.”
“German scientists and their colleagues at the Beijing Genomics Institute in China have been working on uncovering secrets of the outbreak. BGI scientists revised their draft genetic sequence of the E. coli strain and have been sharing their data with dozens of scientists around the world as a way to "crowdsource" this data. By publishing their data publicy and freely, these other scientists can have a look at the genetic structure, and try to sort it out for themselves.”
Downstream consequences:
“Last summer, biologist Andrew Kasarskis was eager to help decipher the genetic origin of the Escherichia coli strain that infected roughly 4,000 people in Germany between May and July. But he knew it that might take days for the lawyers at his company — Pacific Biosciences — to parse the agreements governing how his team could use data collected on the strain. Luckily, one team had released its data under a Creative Commons licence that allowed free use of the data, allowing Kasarskis and his colleagues to join the international research effort and publish their work without wasting time on legal wrangling.”
