Research Data Management: Finding our Role6. December 2013

PIDs and DOI Registration with DataCite

2

Background:

• Easier re-usability and verification of data

• Recognition for collection and documentation of data (Citation Indeces)

• Compliance with funders‘ requirements (e.g German Research Foundation)

• Avoiding duplication

• Motivation for new research

Why publish and cite research data?

3

Persistent Identifier I

• DOI

• Citation of scientific publications

• Established in the scientific community

• Global resolving via any handle server or dx.doi.org/{doi}

• Persistence and data quality are guaranteed

• Handle

• Global referencing of data before publication

• Global resolving via any handle server

• No persistence or quality management

4

Persistent Identifier II

• URN

• Referencing of local documents in a closed system ( e. g. dissertations, thesis)

• Resolving only on server of publisher

• Persistence and data quality are guaranteed

• ARK

• Documents of all work stages

• Persistence declaration available; may be deleted

• Resolving only free of cost on server of publisher

• Quality management (metadata), no standards for persistence

5

The DOI® System

• International DOI Foundation was founded in 1998.

• The DOI system offers long-term persistence andaccessibility of data.

• Based on the Handle system.

• In May 2012 the DOI System ISO Standard 26324 was published.

• Part of the quality control is mandatory metadata foreach object registered with a DOI.

DOI®, DOI.ORG® and shortDOI® are trademarks of the International DOI Foundation

6

A little History

• 2003:DFG-funded project of the TIB with World Data Centres regarding the publication of research data.

• 2005:TIB becomes the first DOI registration agency for research data. From the beginning, grey literature is also registrered.

• 2009-03:Paris Memorandum regarding the cooperation of 6 European information providers.

• 2009-12:DataCite is founded in London with 7 members.

7

DataCite

• Growing demand to make data citable.

• DataCite is an international consortium whose aims are

• to establish easier access to research data on the Internet

• to increase acceptance of research data as legitimate, citable contributions to the scholarly record

• to support data archiving that will permit results to be verified and re-purposed for future study.

• Developement of standards, worflows, and best practices.

• 2013:

• 18 members from 13 countries,

• 9 associated members,

• ~2.2 Million DOIs

9 DOI Registration Agencies

DOI System Infrastructure

10

DataCite Services

• Registration and updating of DOI names.• Storage of metadata.• Accessible via UI or API.

Metadata Store (MDS)

11

DataCite and Metadata

• Metadata make data discoverable.

• Long-term maintenance of metadata is animportant part of the persistence of an identifier.

• Schema is inspired by Dublin Core.

• Core value of the DataCite Metadata Schema:Linking between data and related objects.

• Future vision:Links between all related publications and objects.

12

DataCite Metadata Schema

• Identifier (with type attribute)

• Creator (with type and nameIdentifier attributes)

• Title (with optional type attribute)

• Publisher

• PublicationYear

• Citation:

Creator (PublicationYear): Title. Publisher. Identifier 

Mandatory Properties

13

Citation

Creator (PublicationYear): Title. Publisher. Identifier 

Dataset:Kuhlmann, H et al. (2009): Age models, iron intensity, magnetic susceptibility records and dry bulk density of

sediment cores from around the Canary Islands. PANGAEA - Data Publisher for Earth & Environmental Science.

DataCite Metadata Schema

• Subject (with scheme attribute)

• Contributor (with type and nameIdentifier attributes)

• Date (with type attribute)

• Language• ResourceType (with description attribute)

• AlternateIdentifier (with type attribute)

• RelatedIdentifier (with type and relationType attributes)

Optional Properties

15

DataCite Services

• Search engine for all metadata stored in the MDS.• Filter options to refine the search.

Metadata Search

16

DataCite Services

• Exposes metadata stored in the MDS using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH).

• Different metadata formats are available.

• Service is open to everyone; harvesters include:

• TIB (GetInfo)

• Thomson Reuters (Data Citation Index)

• Elsevier (Exlibris)

OAI-PMH Data Provider

17

Services in Cooperation with CrossRef

• http://crosscite.org/citeproc/A Citation Formater which provides over 100 different formats for citations.

• http://crosscite.org/cn/With Content Negotiation it is possible to access different media types of a registered object (machine-to-machine only).

Content Negotiation

Resolving to a citation:
