Leveraging publication metadata to help overcome the data ingest

bottleneck

• The End To make data archiving integral to scientific

publishing.

• The scope Data underlying findings in the peer-reviewed

biological literature.

• The Means Integrated submission of data with the

manuscript Low barrier to submission (at the datafile level) Free reuse of data (free as in both speech & beer) Journals share responsibility for governance and

sustainability

Venter JC, Eisen JA (2011) Data from: Stalking the fourth domain in metagenomic data: searching for, discovering, and interpreting novel, deep branches in phylogenetic trees of phylogenetic marker genes. Dryad Digital Repository. doi:10.5061/dryad.8384

• Integrated submission Currently integrated or in process: 20 All journals with Dryad content: >70 A minority require data prior to review

• Journals published by a variety of organizations Traditional (incl. Oxford University Press, Wiley-

Blackwell) Open Access (incl. BMC, BMJ Open) Society publishers (e.g. with Allen Press, or

independent)

Dryad vs. Supplementary Online Materials

Dryad SOM

Article citations: reuse of data leads to article citations ✔ ✔

Identifiable: Data DOIs within articles serve as permanent, resolvable identifiers ✔ ✔/✗

Curated: quality control of data submissions and indexing metadata ✔ ✔/✗

Economy of scale: cost efficiency from shared infrastructure ✔ ✔/✗

Discoverable: indexed and exposed to both web and bibliographic search engines ✔ ✔/✗

Ease of deposit: streamlined deposit, allow large and complex datasets ✔/✗ ✔/✗

Formatted for reuse, i.e. not PDF ✔/✗ ✔/✗

Updatable: new versions of data files can be added, metadata can be enhanced ✔ ✗

Preservation planning: integrity audits, format migration, replication, etc. ✔ ?

Support for embargoes: can delay release of data in accordance with journal policy ✔ ?

Free reuse: no paywall, no unecessary IP restrictions/ambiguities ✔ ?

Why Dryad yearns for ORCIDs

• Replace name strings with identities Disambiguation of like names Clustering of synonymous names Confidently recognizing different data packages that

share an author

• Enabling Accurate author searches Internal and external author hyperlinks Aggregation of author contributions Inclusion of data records in the profiles of coauthors Propagation of ORCIDs with Dryad metadata

• Manual curation of names not feasible Only ~20% of Dryad authors in Library of Congress

name auth. file Manual control would explode curation costs

How to get ORCIDs into Dryad

• Ideally sent to Dryad by integrated journals Pre-review/Pre-production: allows coauthors

to edit data packages Post-production: works for all other uses

• Non-integrated journals Lookup API based on article or affiliation

data

• To be avoided Authors required to enter ORCIDs during

submission Authors required to register during

submission

What do we know about authors?

• Names Often abbreviated except for

corresponding or submitting author

• At least one article they have written Title, journal, volume, pages, DOI,

abstract

• Other identifiable information An email for submitting authors Sometimes: institutional affiliation

and contact information for corresponding authors

Some requirements• Recognizing ORCIDs for authenticated

users Mapping to InCommon Silver profiles ORCIDs for organizations (e.g. consortia)

• Dspace support Curator interface for ORCID lookup/verification Lookup/registration option from submission

interface Allowing metadata relationships (e.g. of an

ORCID with a name)

• Mechanisms for curator to Flag duplicates and errors Register provisional ORCIDs Map to other profiles (e.g. InCommon)

Business model issues• Dryad is (will be) supported by

subscriptions and deposit charges, primarily from journals. With a not-for-profit budget

• Feasibility requires wide adoption by publishers And manuscript-submission system

developers!

• Favored model Pay for use of automated lookup services,

with costs scaled by usage level Credit for curator contributions
