GakuNin academic access management federation membership
Nagoya University is a participating institution in GakuNin (学術認証フェデレーション), the Japanese national academic access management federation operated by the National Institute of Informatics, and states so on its own site. Through it the university's THERS account authenticates against federated services including GakuNin mAP (cg.gakunin.jp), meatmail, GakuNin RDM (rdm.nii.ac.jp), GakuNin LMS (lms.nii.ac.jp), mdx, Q-leap LMS, Nature Research, SpringerLink, Atypon and Westlaw. A federation is shared by definition and the IdP behind it is the institution's, so this membership is recorded rather than treated as a shared-host misattribution. The federation's signed metadata aggregate is the machine-readable artifact; it belongs to GakuNin and is not saved here. Note that the university's own documentation of this service exists only on the Japanese surface — the English equivalent returns 404.
