Motivation

National Diet Library (Q477675) persistent identifiers are used for scholarly articles in the National Diet Library (Q477675), and are frequently linked to from CiNii (Q10726338). In the past CiNii (Q10726338) often had direct links to PDFs for article with a NII article ID (P2409) but now it seems this content is being dispersed among the National Diet Library (Q477675), J-STAGE (Q11225111), and elsewhere. Having this property will help identify Japanese scholarly literature, and potentially provide Wikidata users with links to full text. Note that this persistent identifier is different from the existing JPNO (P2687) NDL Bib ID (P1054) NDL Authority ID (P349) properties. My own focus is on the biological taxonomy literature, but other fields of study are also likely to benefit. -- Rdmpage (talk) 13:16, 2 July 2021 (UTC)
