This document provides an overview of DataCite and its infrastructure. It discusses DataCite's history and growth since its founding in 2008, its members and structure as a nonprofit association, its technical infrastructure including services like metadata storage, search, and content negotiation, and its working groups focused on business practices, metadata, and technology. It also outlines DataCite's cooperation with organizations like CrossRef, ORCID, and RDA.

5. 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

Business Models Principles

13. Business Models Principles
• Information for allocation agencies
• Costs/fees schedules; prefixes; membership;
contracts/agreements
• Information for clients
• Commitment to persistent access; landing pages; syntax;
mandatory metadata requirement
• Definitions
• Data sets; data papers; grey literature

14. Data Quality Survey
WHY: Assess DataCite‘s role in ensuring data quality.
 11.-25. June 2013: Online survey within the DataCite community
•What constitutes data “quality”
• No consensus; ‘Data quality’ is an abstract phrase
•How might this quality be assessed
• Scientific context; intended use; disciplinary standards; expert
knowledge; data centres; peer review; metadata and documentation
• What do you see as DataCite’s role in ensuring or assessing quality?
• No direct role (Concept of “usurping” the role of scientific communities;
ensuring data centres/repositories have procedures; Do DOIs actually
indicate quality?); ensure metadata quality
52 responds

15. Outlook
• Create recommendations based on the responses to the survey
• Update the first version of the „Business Models Principles“
(definitions, granularity, landing pages, collaboration among the
members, etc)
• Get opinions from the DataCite community via Google Discussion
Group
• Support the DataCite Board in implementing the strategical plan
2013-2014

16. Metadata Working Group
What we do
• Create and update the Metadata Schema
• Communication with the community
Who we are
• 12 members
• 7 nations (USA, Canada, Germany, UK, Sweden,
Netherlands, France)
