• The End
– To make data archiving and reuse standard within scientific communication.
• The Means
–
–
–
–
–
Enable low-burden data archiving at the time of manuscript submission.
Promote researcher benefits from data archiving.
Promote responsible data reuse.
Empower journals, societies & publishers in shared governance.
Ensure sustainability and long-term preservation.
• The Scope
–
–
–
–
Research data in science and medicine
Primarily data underlying findings in peer-reviewed articles
Also data from some non-peer reviewed publications (e.g. dissertations)
And some non-data content (e.g. software scripts, figures)

The value proposition
• For authors and researchers, Dryad…
– increases the impact of, and citations to, published research
– preserves and makes available others’ data
– frees researchers from the burden of data preservation and access
• For journals, publishers, and societies, Dryad…
– frees journals from the burden of maintaining supplemental data
– supports all varieties of data archiving policies
• For libraries and institutions, Dryad…
– makes data available at no cost, under clear terms of use
– helps fulfill their research data management mandates
• For funders, Dryad…
– provides a cost-effective mechanism to make research more accessible

Data archiving has many benefits
Direct
Verification of published research
Preserving accessibility to data
Allowing reuse and repurposing of
data
Discoverability of data
Indirect (costs avoided)
Redundant data collection
Inefficient legacy data curation
Burden of sharing-upon-request
Opportunity cost of science not
done
Near term
Protection against personnel
turnover
Availability for review and validation
Long term
Secure long-term stewardship
Increased impact per publication
Private
Increased citations
New collaborations
New research opportunities
Fulfilling funding mandates
Public
More efficient use of research
dollars
Public trust in science
Educational opportunities
Improved methodologies
More informed policy
Modified from Beagrie et al. (2009) Keeping Research Data

Dryad focuses on the long tail of orphan data
Specialized repositories
(e.g. GenBank, GBIF)
Volume
Many datasets belong to
the long tail. Though less
standardized, they can be
rich in information content
and have unique value
Orphan data

Why use Dryad rather than Supplementary Online Materials?

Discoverable: indexed and exposed to both web and bibliographic search engines

Identifiable: DataCite DOIs within articles serve as permanent, resolvable identifiers

Ease of deposit: streamlined deposit, allowance for large and complex datasets

Updatable: new versions of data files can be added, metadata can be enhanced
✔
✗
Support for embargoes: can delay release of data in accordance with journal policy
✔
✗
Free reuse: no paywall, clear terms of reuse (all data released under CC Zero)

A “Data Package” is all of the data files for a journal article. All Dryad data
packages link to the associated journal article.

Dryad integrates article and data submission
Dryad works with the manuscript workflow of journals to:
– Simplify the process of data submission for authors,
– Allow authors to deposit, to a single repository, gigabytes of
data files in their original formats,
– Ensure permanent bidirectional links between the article and
the data, and increased visibility for both,
– Ensure that the data is accessible once the article becomes
available,
– Offer the option of making data available for editorial or peer
review, via secure access for editors and reviewers,
– Give authors the option to embargo public access to data for a
limited time after publication, if permitted by the journal's data
policy.
Options are customized to meet the requirements of each journal.

Trustworthy repository infrastructure
• Making data available is the primary mission of the organization
– No pay-walls or restrictive licenses (all released under CCZero)
– The same data may be hosted by other services (non-exclusivity)
• Built on the DSpace repository platform, an open source framework
used by hundreds of institutional repositories
• Multiple machine and human interfaces for discovery and access
– Dublin Core metadata, harvestable through OAI-PMH
– DOIs registered through DataCite
– Curators add metadata to enhance keyword searching
• Assurance of data integrity and permanent availability
– Service mirroring and backup
– File migration and bit-level integrity assurance
– Organizational failover through DataONE and CLOCKSS

Dryad as an organization
• Governed by an interim Board 2009- 2011.
• Now a nonprofit organization incorporated in North
Carolina, USA.
• Membership open to all stakeholder organizations,
including scientific societies, publishers, funding
agencies, universities & institutes.
• Governed by an elected 12-member Board of Directors
– Nominated and elected by the Membership
• First Annual membership meeting 24 May 2013 in
Oxford.

Dryad’s business plan
• Deposit fees are the primary source of
revenue, for several reasons:
– The time of deposit is when the majority of costs are
incurred
– Revenue scales with costs (i.e. volume of deposits)
– The costs are distributed both fairly and widely
– This enables Dryad to make access to the data free in
perpetuity
• Membership fees will cover costs of annual
membership meetings
• Project grants will supplement the operational
budget for R&D activities
