caption_attribution_description: English: Embargoes chosen by Dryad data authors. (A) Embargo selections of Dryad data authors for the 10,108 files in Dryad (http://datadryad.org/) deposited from inception to September 20, 2013. Data include only datasets related to articles published in journals for which the authors had the option of selecting an embargo. (B) Long-term embargoes (&gt;1 year) by journal that granted them. Data were obtained from [42]. doi:10.1371/journal.pbio.1001779.g002
context_page_description: Dryad is an international open-access repository of research data, especially data underlying scientific and medical publications. Dryad is a curated general-purpose repository that makes data discoverable, freely reusable, and citable. The scientific, educational, and charitable mission of Dryad is to provide the infrastructure for and promote the re-use of scholarly research data.
  The vision of Dryad is a scholarly communication system in which learned societies, publishers, institutions of research and education, funding bodies and other stakeholders collaboratively sustain and promote the preservation and reuse of research data.
  Dryad aims to allow researchers to validate published findings, explore new analysis methodologies, re-purpose data for research questions unanticipated by the original authors, and perform synthetic studies such as formal meta-analyses. For many publications, existing data repositories do not capture the whole data package. As a result, many important datasets are not being preserved and are no longer available, or usable, at the time that they are sought by later investigators.
context_section_description: Dryad enables authors, journals, societies and publishers to facilitate data archiving at the time of publication, when the data are readily available.  Data in Dryad receives a permanent, unique Digital object identifier (DOI), which can be included in the published article so that readers are able to access the data.   Authors can archive data in Dryad and be assured of its preservation, while satisfying journals' and research funding agencies' mandates to disseminate their research outputs.
  Authors submit data to Dryad either when the associated article is under review or has been accepted for publication.  The choice depends on whether the journal includes data within the scope of peer reviewer.  Authors may also submit data after an article has been published.
  Data submission is facilitated by journals sending notices of new manuscripts to Dryad.  This saves authors from having to re-enter the bibliographic details when they upload their data files.
  Dryad curators review submitted data files and perform quality control on metadata descriptions before inclusion of new content in the repository. Dryad’s metadata approach emphasizes simplicity and interoperability, supported by a Dublin Core metadata application profile. The Metadata Research Center now at the College of Computing and Informatics, Drexel University, formerly served as Dryad’s central curation hub, with primary curation activity now taking place via the non-profit in North Carolina. 
  Dryad coordinates data submission to specialized repositories where in order to (a) lower user burden by streamlining the submission workflow and (b) allow Dryad and specialized repositories to exchange identifiers and other metadata in order to enable cross-referencing of the different data products associated with a given publication.  The first two handshaking partners are TreeBASE and GenBank, which Dryad's partner journals have previously identified as required points of deposition for phylogenetic tree data and DNA sequences, respectively.
