Outline •  Introduc2on •  What is Dryad Digital Repository? •  Preserva2on policy development process •  Dryad preserva2on policy •  Lesson learned and open ques2ons •  Conclusion •  Acknowledgement

Introduction •  “Data deluge” •  Journals and funding agency mandates •  Benefits to archiving and preserving research data:

–  Facilitates: •  Verifica2on of research •  accessibility and discoverability •  opportuni2es for data reuse •  increased cita2ons •  research visibility

–  Prevents: •  redundant data collec2on •  inefficient legacy data cura2on •  burden of sharing-‐on-‐request

•  Challenges of data archiving: –  Wider variety of file formats than most digital archival materials. –  New versions as data sets are added to and updated –  Security considera2ons –  Large amounts of data

Benefits adapted from Beagrie N, Lavoie BF, Woollard M (2010) Keeping research data safe 2. HEFCE

Why preservation policy?

•  Preserva2on policy supports strategic planning for implementa2on

•  Communicates to stakeholders –  trustworthiness and commitment to preserva2on

•  Not many data preserva2on policies. Some examples: –  CERN: CMS data –  Archaeology Data Service –  NSIDC Data Management Policies –  Odum Ins2tute Preserva2on Policy –  ISPSR –  DataONE

Dryad Digital Repository •  A curated, general-‐purpose repository that makes the

data underlying scien2fic and medical publica2ons discoverable, freely reusable, and citable (hap://datadryad.org/).

•  Facilitates data availability, data sharing, and scholarly communica2on.

•  Originally partnered with leading journals and scien2fic socie2es in evolu2onary biology and ecology.

•  Broad collec2ng policy – almost any data is accepted, as long as it is associated with a publica2on.

Dryad and Preservation Needs •  Preserva2on is a major part of Dryad’s mission. •  Current preserva2on ac2ons:

–  MD5 Checksums –  provenance metadata –  informal encouragement of preferred formats

•  Developing and implemen2ng a formal preserva2on policy will: –  guide current and future preserva2on prac2ce –  Facilitate the long-‐term preserva2on of the repository’s digital

assets

Policy Development Process

2012 Feb 2013 May 2013 July 2013 Nov 2013

An ini2al preserva2on plan (version 1.0.)

Preserva2on Working Group in Feb 2013

Version 2.0. presented to the Dryad Board of Directors

Version 2.0. revised in coopera2on with Dryad staff

•  Version 2.4. Approved by Dryad Board of Directors

•  Preserva2on Working Group dissolved.

Preserva2on Task Force formed

Preservation Policy •  Purpose •  Scope and content coverage •  Overview of preserva2on strategies •  Format support and levels of preserva2on

–  e.g. Preferred formats and format support levels

•  Implemen2ng the strategy –  e.g. integra2ons of OAIS func2onal ac2vi2es, pre-‐ingest &

ingest, and archival storage, authen2city and integrity, security, versioning, and withdrawal of collec2ons

•  Sustainability plans –  e.g. technical sustainability, ins2tu2onal and financial

sustainability

Lesson Learned and Open Questions

•  A nego2a2on between what is ideal and what is realis2c –  Adop2ng Interna2onal standards, models, and best prac2ces exist for long-‐term preserva2on •  Open Archival Informa2on System (OAIS) reference model (ISO 14721:2003)

•  PREMIS (PREserva2on Metadata: Implementa2on Strategies)

–  Other standards and guidelines about audit and cer2fica2on for building a trusted digital repository •  Trustworthy Repositories Audit & Cer4fica4on: Criteria and Checklist (TRAC) and Data Seal of Approval (DSA)


•  Aligning with other internal and ins2tu2onal policies –  Follow Dryad’s internal policies, we looked primarily to Dryad’s Terms of Service document (haps://datadryad.org/pages/policies), which includes policies on submission, content, payment, usage, and privacy

–  Comply with Dryad’s unofficial policies, which have yet to be finalized •  A policy-‐in-‐progress: Dryad’s policy on versioning

–  Comply with policy from partner ins2tu2ons •  Dryad func2ons as a partnership between the University of North Carolina at Chapel Hill (UNC), Duke University (Duke), and North Carolina State University (NC State)


•  Structuring the policy according to Dryad’s specific needs –  Mee2ng specific organiza2onal needs is fundamentally important and should be the first considera2on in all work, as each organiza2on has different goals, priori2es, and capabili2es.

–  Data depositors’ requirements: minimum requirements •  balance “minimum efforts” and having “enough” representa2on informa2on

•  compensated by other factors

Conclusion •  Policy-‐crea2on and planning are just first steps -‐-‐

implementa2on will require further considera2ons •  Future plan

–  Poten2als for implemen2ng TRAC / DSA in the future –  Divide policy and implementa2on into separate documents

–  New Task Force
