DOI

Digital Object Identifier (DOI)
DOIs provide persistent links to scholarly content, helping users get to the authoritative, published version of the content they are searching for, even when the content changes location or ownership. PANGAEA was the first data system on the Internet, using DOI for the persistent identification of scientific data. Its DOI consists of the prefix 10.1594 which is assigned to the publication of primary data through the agent TIB and a suffix, separated by a slash /. The suffix is composed of the data system/center PANGAEA and an individual ID which in Pangaea is the internal ID automaticaly assigend by the relational system to a data set. A valid Pangaea-DOI may look like 10.1594/PANGAEA.123456.

Citation and DOI are defined during three steps of a data sets publication process:
 * 1) If a data set is imported and the status is set to validated it receives an interneal ID which can be resolved as a preliminary DOI through doi.pangaea.de only.
 * 2) If a data set status is set to published the internal ID is changed to a global resolvable technical DOI after 4 weeks and the data set becomes citable.
 * 3) On request the DOI can be defined as an offical publication DOI with the citation included in the library catalog of the TIB (http://tws.gbv.de). If several data sets should be made citable, a new parent DOI my be defined by the systems editor.

PangaVista and the DOI resolver of PANGAEA can be used for any registered DOI (including preliminary DOIs of Pangaea).

The German WDC cluster (WDC-Climate, WDC-MARE, WDC-RSAT, WDC-TERRA, in prep) and the TIB is running the DFG project STD-DOI to establish the DOI-system for data publications.
