A Calibre metadata source plugin that uses the catalogue (https://portal.dnb.de) of the Deutsche Nationalbibliothek (DNB) to retrieve metadata. DNB is the German central archival library. German publishers are required to send them a copy of every book for archival, so it's the largest metadata source for literature published in Germany.
This plugin supports retrieval of DNB-IDN, ISBN, authors, title, edition, tags, publication date, languages, publisher, comments, series, series index and cover.
For books without series information it can try to extract series and series index from the title. GND and/or non-GND subjects can be used as tags.
This plugin works with Python 2 and Python 3.
