Digital Object Identifier (DOI)
PANGAEA was the first data system on the Internet, using DOI for the persistent identification of scientific data.

The DOI resolver of PANGAEA, can be used for all official DOIs and also unoffical/unpublished data set DOIs in PANGAEA: http://doi.pangaea.de/

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