DataCite –Persistent links to scientific data

Jan Brase, DataCite – TIB

1st PRELIDA workshopPISA, June 26th

High visability of the content

Easy re-use and verification.

Scientific reputation for the collection and documentation of content (Citation Index)

Encouraging the Brussels declaration on STM publishing

Avoiding duplications

Motivation for new research

What if any kind of scientific content would be citable?

Digital Object Identifiers (DOI names) offer a solution

Mostly widely used identifier for scientific articles

Researchers, authors, publishers know how to use them

Put datasets on the same playing field as articles

DatasetYancheva et al (2007). Analyses on sediment of Lake Maar. PANGAEA.doi:10.1594/PANGAEA.587840

URLs are not persistent

(e.g. Wren JD: URL decay in MEDLINE- a 4-year follow-up study. Bioinformatics. 2008, Jun 1;24(11):1381-5).

DOI names for citations

How to achieve this?

Science is global• it needs global standards• Global workflows• Cooperation of global players

Science is carried out locally• By local scientist• Beeing part of local infrastrucures• Having local funders

Global consortium carried by local institutions

focused on improving the scholarly infrastructure around datasets and other non-textual information

focused on working with data centres and organisations that hold content

Providing standards, workflows and best-practice

Initially, but not exclusivly based on the DOI system

Founded December 1st 2009 in London

2012: STM, CrossRef and DataCite Joint Statement

1. To improve the availability and findability of research data, the signers encourage authors of research papers to deposit researcher validated data in trustworthy and reliable Data Archives.

2. The Signers encourage Data Archives to enable bi-directional linking between datasets and publications by using established and community endorsed unique persistent identifiers such as database accession codes and DOI's.

3. The Signers encourage publishers and data archives to make visible or increase visibility of these links from publications to datasets and vice versa
