DOI registration with DataCite

2

• German National Library of Science and Technology. Scope: all areas of engineering, as well as architecture, chemistry, information technology, mathematics and physics.

• Evaluation by external international reviewers every 7 years (lastly 2011-02)

• Outcome (amongst others): Particularly worth mentioning is the operation of the national DOI registration agency for referencing research data. With it, the TIB offers an innovative and important service that is acknowledged internationally.

A little History

• 2003:DFG-funded Project of the TIB with World DataCenters 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.

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.

• 2013:

• 17 members from 12 countries,

• 5 associated members,

• ~1.5 Million DOIs

5

The DOI System

• 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

DataCite Clients

• DataCite registers DOIs for

• Research data,

• Non-textual materials (e.g. videos, software, images),

• Grey literature.

• Mostly academic and non-commercial clients.

• Clients are responsible for data archival (= data centers).

Requirements for the DOI registration

• Commitment to data persistence

• Metadata delivery

• Provision of landing pages

• Granularity of data (cite-worthy?)

• DOI syntax:

• Use opaque strings

• Use only: A-Z a-z 0-9 . : - _ /

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.

11

DataCite Metadata Schema

• Identifier (with type attribute)

• Creator (with type and nameIdentifier attributes)

• Title (with optional type attribute)
