PanDOI works as Windows Desktop Gadget on Windows Vista and higher or as a Widget for OS X Dashboard. It resolves persistent identifiers like Digital Object Identifier (DOI), Handel (hdl), Uniform Resource Name (URN), and sRef IDs. It is possible to open a PANGAEA dataset by its ID, to show the latest PANGAEA datasets, and to search through PANGAEA. See further details for the manual of PanDOI.
