Dryad is delighted to join with PLOS today to announce our partnership with PLOS Biologyas described here on the official PLOS Biology blog, Biologue.  As the first Public Library of Science (PLOS) journal to partner with Dryad to integrate manuscript submission, “PLOS Biology can offer authors a seamless tying together of an article with its underlying data; [and] can also provide confidential access for editors and reviewers to data associated with articles under review.”
PLoS Biology - www.plosbiology.org

Here’s how it works: During manuscript evaluation, PLOS Biology invites authors to deposit the underlying data files in Dryad, sending them a link to Dryad which enables a streamlined upload process (no need to enter the article details).  Authors may deposit complex and varied data types in multiple formats, and these files are then accessible to editors and reviewers by anonymous and secure access during the manuscript review process.  Behind the scenes, the journal’s editorial system and the Dryad repository exchange metadata, ensuring that upon publication, the article links to the associated data in Dryad, and permanently connecting the published article with its securely archived, publicly available data.

Dr. Theodora Bloom, Chief Editor, PLOS Biology, mentions that journals “are uniquely well-placed to help researchers ensure that all data underlying a study are made available alongside any published articles.”

We welcome PLOS Biology authors and editors to Dryad, and look forward to extending this partnership to other PLOS journals.

A number of enhancements to the repository have been made in recent months, including these three that were in high demand from users:

  • First, we have modified our submission process to enable the data to be deposited prior to editorial review of the manuscript. Journals that integrate manuscript and data submission at the review stage can now offer their editors and peer reviewers anonymous access to the data in Dryad while the manuscript is in review. This option is currently being used by several of our partner journals, BMJ Open, Molecular Ecology, and Systematic Biology, and is available to any existing or future integrated journal. Note: authors still begin their data deposit process at the journal.
  • Second, when authors submit data associated with previously published articles, they can pull up the article information using the article DOI or its PubMed ID, greatly simplifying the deposition process for legacy data.
  • Third, Dryad now supports versioning of datafiles. Authors can upload new versions of their files to correct or update the original file. Once logged in to their Dryad account, the My Submissions option appears under My Account in the left side-menu. Prior unfinished and completed submissions are listed; selecting an archived submission allows the author to add a new file.  Note that the earlier versions of the file will still be available to users, but the metadata may be modified to reflect the reason for the update. The DOIs will be appended with a number (e.g., “.1”, “.2”) so that each version can be uniquely referenced.  By default, users will be shown the most current version of each datafile.  They will be notified of the existence of any previous/subsequent versions.
  • Access and download statistics have been displayed for content in the repository since late 2010; Dryad now displays the statistics for an article’s data together on one page so you can see at a glance how many times the page has been viewed and how many times each component data file has been downloaded. Check out this example from Evolutionary Applications.

Perhaps it’s understandable that paleontologists are committed to preserving the scientific record, since they spend a lot of time and energy finding and extracting shreds of evidence millions of years old.  Now, thanks to a partnership between Dryad and The Paleontological Society announced last year [1], coupled with strong data archiving policies adopted by two of its journals (Paleobiology and the Journal of Paleontology), a rich trove of data will be available for future researchers to unearth from Dryad.

For both journals, authors are being instructed to deposit the underlying data at the time their manuscript is submitted, so that editors and referees will be able to review it prior to acceptance.  Once published on Dryad, the data will be independently discoverable and citable, while at the same time prominently linked both to and from the original article.  Researchers are able to track the reuse impact of their data, independent of the citation impact of their article, by monitoring downloads from Dryad.

Preserved for ages.

doctor silencedA recent issue of BMJ highlighted the problem of missing clinical trial data from medical research, exploring both the causes and consequences of unpublished evidence.  One of the articles, from Andrew Prayle and colleagues [1], examined compliance with the US Food and Drug Administration’s ostensibly mandatory requirement that clinical trials report their results in ClinicalTrials.gov, as required by the the FDA Amendments Act (FDAAA) of 2007. Alarmingly, they found that only 22% of trials that should have reported results had actually done so.  Interestingly, industry-funded trials reported results at a higher frequency than other funders.  They conclude:

If the reporting rate does not increase, the laudable FDAAA legislation will not achieve its goal of improving the accessibility of trial results.

Fortunately for those interested in this research, the authors have ensured that their own data are available by depositing them in Dryad, where they have already been downloaded by over 100 users.

For more on the disturbing state of affairs in reporting of clinical trial data, we offer the irrepressible Ben Goldacre speaking at the Strata 2012 conference in February.

Until recently, Mark Hahnel was a PhD student in stem cell biology. Frustrated by seeing how much of his own research output didn’t make it to publications, he endeavored to do something about it by developing a scientific file sharing platform called FigShare. Recently, Mark and FigShare were taken under the wing of Digital Science, a Nature Publishing Group spinoff, and a sleek new FigShare was relaunched in January 2012 with many more features and an ambitious scope.

FigShare allows researchers to publish all of their research outputs in seconds in an easily citable, sharable and discoverable manner. All file formats can be published, including videos and datasets that are often demoted to the supplemental materials section in current publishing models. By opening up the peer review process, researchers can easily publish null results, avoiding the file drawer effect and helping to make scientific research more efficient.

Users do not have to pay for access to the content: public data is made available under the terms of a CC0 waiver and other content under CC-BY.  And FigShare is currently providing unlimited public space and 1GB of private storage space for free.

This is a promising solution for getting negative and otherwise unpublished results out into the world (figures, tables, data, etc.) in a way that is discoverable and citable.  Importantly, much of this content would not be appropriate for Dryad, since it is not associated with (and not documented by) an authoritative publication.

There are clearly some challenges to the FigShare model.  A big one, shared with many other Open Science experiments that disseminate prior to peer review, is ensuring that there is adequate documentation for users to assess fitness for reuse.  Another challenge that Dryad is greatly concerned about is guaranteeing that the content will still be usable, and there will be the means to host it, ten or twenty years down the road.  These are reflections of larger unanswered questions about how the research community can best take advantage of the web for scholarly communication, and how to optimize filtering, curating or preserving such communications. To answer these questions, the world of open data needs many more more innovative projects like FigShare.

Considering FigShare’s relaunch suggests a few strengths of the Dryad model:

  • Dryad works with journals to integrate article and data submission, streamlining the deposit process.
  • Dryad curators review files for technical problems before they are released, and ensure that their metadata enables optimal retrieval.
  • Dryad’s scope is focused on data files associated with published articles in the biosciences (plus software scripts and other files important to the article.)
  • Dryad can make data securely available during peer review, at the request of the journal.
  • Dryad is community-led, with priorities and policies shaped by the members of the Dryad Consortium, including scientific societies, publishers, and other stakeholder organizations.
  • Dryad can be accessed programmatically through a sitemap or OAI-PMH interface.
  • Dryad content is searchable and replicated through the DataONE network, and it handshakes with other repositories to coordinate data submission.

A file sharing platform and a data repository are different animals, to be sure; both have a place in a lively open data ecosystem. We wish success to the Digital Science team, and look forward to both working together, and challenging each other, to better meet the needs of the research community.  To see what other options are out there for different disciplines and types of data, DataCite provides an updated list of list of research data repositories.

Our last post celebrated the 1000th data package in Dryad. This week, with the release of two data packages associated with articles in Ecological Monographs, we celebrate another important milestone, our 100th journal.

We believe this validates one of the premises on which Dryad was founded, that a non-specialist data repository can serve as shared infrastructure for a large and diverse set of journals.  As a group, they have little in common, serving authors and readers from many different research communities, nationalities, types of institutional affiliation, etc., and working with many different kinds of data.  Some are owned by societies, some by commercial publishers, some by not-for-profits.  Some are Open Access, many are not.  Some have specialized disciplinary or taxonomic scope (e.g. including journals that publish on birds, herps, insects, mammals, plants, protists, viruses, etc.) while some publish findings from all corners of science (Nature, PNAS, Science).

Interestingly, this set of 100 is roughly five times the number of journals that have integrated manuscript submission with Dryad in order to facilitate authors’ data archiving.  While the integrated journals still account for the majority of new data submissions, we are pleased to continue receiving data volunteered by authors publishing in outlets new to Dryad.

The journals that have integrated their manuscript processing with Dryad to date are mostly, though not exclusively, from the fields of evolutionary biology and ecology:

  • The American Naturalist
  • Biological Journal of the Linnean Society
  • BMJ Open (an important first step in that it is our first integrated biomedical journal)
  • Ecological Monographs
  • Evolution
  • Evolutionary Applications
  • Heredity
  • Journal of Evolutionary Biology
  • Journal of Heredity
  • Molecular Ecology and Molecular Ecology Resources
  • Paleobiology
  • Pensoft Publishers – 8 different journals
  • Systematic Biology

But Dryad’s broadening disciplinary coverage is best illustrated by listing some of the journals with content in the repository that have not, at least not yet, implemented integrated submission:

  • Animal Behaviour
  • Bioinformatics
  • Biotropica
  • Conservation Genetics
  • Environmental Microbiology
  • Evolution and Development
  • Frontiers in Psychology
  • Genome Biology and Evolution
  • Human Genomics
  • Integrative and Comparative Biology
  • Journal of Biogeography
  • Journal of Fish and Wildlife Management
  • The Journal of Parasitology
  • Limnology and Oceanography
  • The Plant Cell
  • PLoS Pathogens
  • Symbiosis
  • Toxicon

And we are particularly pleased by the irony of hosting data from Genesis😉

If you are an editor, publisher, or just a passionate reader of a journal that currently has content in Dryad (you can find out for yourself here), and you would like to talk about how manuscript submission integration could strengthen the service that Dryad provides to your journal, then please contact us.
