Problem and Solution
Shortcomings in data provision and interdisciplinary use Rules of good scientific practise are not taken into account in all
cases. Data sources are widely unknown. Data are achived without context. Data cannot be cited as independent entities
Method of solution: publication of primary data as independent entities Persitent Identifier with global resolving mechanism for data archive
and context referencing (scientifc datamodel at archive level) Integration into library catalogues in order to find data together with
articles STD-DOI application profile: meta data kernel + items for electronic
publication (interface between scientific data archives and libraries)

Credits in Science
"Citation Index": Scientific efficiency is "measured" by publications.
Extra work for data publication is currently not acknowledged. Data processing, context documentation, quality assurance.
Recommendation: Data publications should be included in the standard scientific "Citation Index". Motivation of the individual scientist. Connection between person and primary dataset.
Citable Data publications support the rules of good scientific practise. encourage inter-disciplinary data utilisation. Make data searchable in library catalogues together with articles Closes the gap between scientifc literature and related data sources

Criteria for Persistent Identifier Allocation
Critical points are securing of data quality and stable connection between identifier and data entity
Allocation is restricted to syntax control and completeness, i.e. expert data description and long-term archiving
Scientific quality assurance is expected by the author and will be reviewed during the allocation process.
Published primary data cannot be changed like published articles.
Stable connection between identifier reference and data entity as well as long-term availability of the primary data are essential and must be ensured (e.g. ICSU WDC's)

Primary data publication
• During her research for the World Data Center Climate (WDCC) the scientist Mrs. Weather gains primary data about the weather in Hannover in the year 2003.
• As usual the primary data is tested, evaluated, stored and administrated at the WDCC.
• In addition Mrs. Weather registers the primary data at the TIB (Primary data publication by STD-DOI/URN assignment)
J.Brase (L3S) + M.Lautenschlager (WDCC) / 18.06.04 / 17
Registration of primary data
• After quality assurance WDCC transmits to the TIB the URL where the data can be accessed, together with a XML-file containing all relevant metadata (generated from scientific data model)
• Including all information obligatory for the citing of electronic media (ISO 690-2)
• language• publisher• publishing date• publishing place
•author•title•size•edition
J.Brase (L3S) + M.Lautenschlager (WDCC) / 18.06.04 / 18
Identifier• The TIB is saving this information about the primary data and awards the primary data with a unique identifier for registration: a DOI
• DOI (Digital Object Identifier) is a system for persistent and actionable identification and interoperable exchange of intellectual property on digital networks• Coordinated by the International DOI foundation (IDF)

Citing primary data
In her publications, Mrs. Weather is now citing this primary data with its unique DOI, maintaned from the TIB:
doi:10.1594 /WDCC/W_Han_2003_MMB_2
10.1594 (Prefix) stands for the TIB as the registration agency.
WDCC stands for the respective research institute. W_Han_2003_MMB_2 is the internal name of the
Data

Resolving the DOI
These DOI can be resolved (and the data can be cited) in every browser worldwide in three ways:• http://dx.doi.org/10.1594/WDCC/W_Han_2003_MMB_2• http://doi.tib-hannover.de:8000/10.1594/WDCC/

Usage scenario 1
• Mr. Storm is reading publications from Mrs. Weather in a journal and would like to analyse her data under different aspects.
• In his publication ”Comparison of the weather from Hannover and Miami” Mr. Storm cites Mrs. Weathers data using its DOI, refering to the uniqueness and own identity of the original data.
• Citation example: Weather, 2003: Weather in Hannover for 2003. [doi: 10.1594/WDCC/W_Han_2003_MMB_2]
J.Brase (L3S) + M.Lautenschlager (WDCC) / 18.06.04 / 25
Usage scenario 2
• Mr. Nice is writing a paper about the sales figures of ice cream in Hannover in 2003, but he has no information about the weather.
• He uses the TIB as the central registration agency to start a metadata search over the registered primary data.
• The result is doi:10.1594/WDCC/W_Han_2003_MMB_2• He resolves the DOI to find the data sufficient.• The metadata refers him to the WDCC as publisher and
data archive.• In his paper he cites the data again using their DOI.

URN
In cooperation with the German Library (DDB) in Frankfurt, every dataset is also registered with an unique URN, having the same structure as the DOI:
DOI-Structure: 10.1594/WDCC/W_Han_2003_MMB_2
URN-Structure:Urn:TIB:10.1594/WDCC/W_Han_2003_MMB_2

Current situation
• In cooperation with World Data Center Climate (WDCC), Max Plank Institut
für Meteorologie, Hamburg• Geoforschungszentrum Potsdam• World Data Center MARE, Uni. Bremen and Alfred
Wegener Institute Bremerhaven• Learning Lab Lower Saxony, Uni. Hannover
the TIB Hannover now is the world‘s first registration agency for scientific and technical data (STD-DOI).

Technical
• A Handle server is installed at the TIB Hannover, so TIB is able to register and resolve DOIs.
• The TIB officially received a DOI Prefix (10.1594)• The first data sets have been stored at the TIB by hand.• The automatic registration process is under
development.
