After an update of the URN service of the German National Library (DNB) at https://nbn-resolving.org, URNs of the type URN granular 2, recognizable by the component “/fragment/”, are currently not resolved correctly and are not forwarded to the presentation system of the ULB. Instead, an error message appears stating that the URN is not registered. This is an error in the DNB’s URN service. The DNB has been informed about the problem and has promised to rectify the error. We will inform you here as soon as the problem has been fixed.
Granular URNs are used to persistently link to a specific page of a work and remain valid even after the data has been moved to another server.
Work URNs and granular URN 1 (without the “/fragment/” component) are not affected by the problem.
