1. Frauke Ziedorn IATUL Workshop 2013 Research Data Management: Finding our Role 6. December 2013 PIDs and DOI Registration with DataCite

2. 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. 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. 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. 5 The DOI ® System International DOI Foundation was founded in 1998. The DOI system offers long-term persistence and accessibility 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 for each object registered with a DOI. DOI ®, DOI.ORG ® and shortDOI ® are trademarks of the International DOI Foundation

6. 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. 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

10. 10 DataCite Services Registration and updating of DOI names. Storage of metadata. Accessible via UI or API. Metadata Store (MDS)

11. 11 DataCite and Metadata Metadata make data discoverable. Long-term maintenance of metadata is an important 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.
