DOI / URN - Assigning
DOI (Document Object Identifier) und URN (Uniform Resource Name) are so called persistent identifiers. They identify electronic objects and are very helpful for citing documents. With the help of resolving systems these identifiers always hint to the current location of a document on the web.
The library can offer both systems. For GFZ publications like STR (DOI and URN) and PIK reports (URN) we assign such identifiers as a standard. But we can also handle other publications like conference proceedings like this. Furthermore the library can assign DOI to data publications.
