2. www.pangaea.de GESIS workshop, Bonn 2011 DOI - Operational System International DOI Foundation (IDF) launched 1998. Currently used by c. 4,000 naming authorities –assigners e.g. 3,000 publishers, data repositories, EU Documents, science data sets, etc. ~43 million DOI names assigned to date ~60 million DOI resolutions per month Well established in professional information sector –best known applications are CrossRef (www.crossref.org ) and DataCite (www.datacite.org )www.crossref.orgwww.datacite.org Draft International Standard (ISO TC46 )

3. www.pangaea.de GESIS workshop, Bonn 2011 DOI – Operational System Use of identifier syntax and network resolution mechanism (Handle System®) Persistence ensured through combination of –improved handle infrastructure (registry database, proxy support) –social infrastructure (obligations by Registration Agencies - RA) Use of a semantically interoperable data model and grouping mechanisms. –multiple resolution, data typing, “Application Profiles”

4. www.pangaea.de GESIS workshop, Bonn 2011 DOI - Organisation International DOI Foundation members Operating Federation Registration Agencies (RA) Clients

5. www.pangaea.de GESIS workshop, Bonn 2011 DOI – Business Model IDF receives membership fees from RAs, contracts technical operator RAs also pay operational fees to IDF’s technical operator for registering and maintaining DOI names (sliding scale per volume) Assigners are customers of RAs RAs might have their own existing numbering scheme RAs are autonomous independent bodies. They offer services to assigners using DOI names –RAs’ business model with their customers is entirely autonomous –RAs only obligation to IDF is a licence/operating agreement

6. www.pangaea.de GESIS workshop, Bonn 2011 DOI system – added value DOI is a brand DOI resolving infrastructure Offer you the opportunity to build added-value services Strong linkage with academic publishing! DataCite as DOI registry for scientific data –Organised as an international association of libraries –Developed by ICSU World Data Centers and Services (German cluster) & the Technical Information Library in Hannover (TIB) Will be adopted by ICSU World Data System (associated member of DataCite)

8. www.pangaea.de GESIS workshop, Bonn 2011 Contra Insufficient funding (of course) Organisation and quality of data services are not consistent IT development is fast – no time for legacies Fragmentation of efforts Pro Long standing experience & know how & motivation Good context with science Open access for all data resources As a whole a very large global data management capacity Trans-disciplinary ! Initial position of WDS

11. www.pangaea.de GESIS workshop, Bonn 2011 Why do we need publishing systems for scientific data? Good data availability fosters large scale & complex science approaches. „Data recycling“ is more effective than re-production. General data availability is low compared to data production. Available data are often not usable because the quality cannot be estimated. Prerequisite for the verification of scientific results. Benefit to data producers (publications = science currency)

12. www.pangaea.de GESIS workshop, Bonn 2011 Data publishing - prerequisites and current status DOI assigners (agents) need to be certified –Certification agency – CA following the OECD principles and guidelines for access to research data (2007) peer-review procedures citability –persistent identifiers (DOI) –ICSU SCOR & Codata working groups on data citation –Science citation index -> Thomson Reuters Web of Knowledge Metadata/Data standards & protocols
