Investigation date: 2026-02-24 Target: GakuNin RDM (GRDM) Search API Source code: RCOSDP/RDM-osf.io (website/search/ directory) Developer guide: RCOSDP/RDM-developer-guide Note: Official documentation for the Search API could not be found. This article is an investigation record based on both the actual API behavior and the source code. Overview GakuNin RDM is a fork of OSF (Open Science Framework), and its source code is available on GitHub (RCOSDP/RDM-osf.io). The search functionality implementation is in the website/search/ directory and consists mainly of the following files. ...

Introduction This article describes the development of a metadata management system for research data that integrates GakuNin RDM (Research Data Management) with the Dydra RDF database. This system can handle file management for research projects and the registration and search of Dublin Core metadata in an integrated manner.

Overview I prototyped a TEI/XML file creation app using Google Cloud Vision API and GakuNin RDM, so this is a memo of that work. Background I needed an environment for creating TEI/XML files that reflect OCR results using Google Cloud Vision API. So I prototyped an environment that uses GakuNin RDM as the backend to manage files per user and execute OCR. How to Use Creating a Folder Access the following. ...

Overview In the following article, I introduced building applications using the GakuNin RDM API. In this article, I introduce how to search files in linked storage using the GakuNin RDM API. Implementation Example I implemented the search API as follows. Since directly accessing https://rdm.nii.ac.jp/api/v1/search/file/ from the client caused CORS errors, I implemented it as a Next.js API Route. i i i e } m m m x p p p p c c c c c c c c } c } c r o o o o o o o o o o o o ; o ) o e r r r r n n n n n n n n a s h e } n m h } b ; n t t t t t s G s s s s s s s p o i l , s e e , o s u t e t t t t t t t i r g a q } f s t t a " A d t r { { { a t _ t h s u , r i h d C u y n s s u q o s a a p v : l t e f } o z r o e o t : d N a g y e q r u f i c p a e i i r i , m e e d r n h a N e u e n s u l e f z c i r r " g c y l q } : , s : s t o J t e x t t c s e r s e e U a s c h s : t u , : e r S a x t h S i r = y e s r m i r t e e e q } o = " n i O t R O e f o y t = s l s o e : a { r r u , f P { t z N = R e p r u n n = T n a r e y e d f ] q a l f a O - a . e s t v n p e = p o = = : t " c d : r e i , u n e s w S T t s a s p i e c = a w u a k e t h : y f e " " " " " " " e a n e a T y i t w p o o r t r r p r e " { { d i _ { _ a l _ t d j s a a r l i t i " p o r a o n n S i a a U l a s n h _ t d { s u d a i e o c l l y y e , t , e n i i n s s e o w m R . r e t v d l s t l s l t s b h l l , z n " : n t s e s n a e L s s I = t e e e l r t : l l c ^ o _ _ e t f : g e } s i t ( e e n p n s : : i _ " e r 1 o j s _ : e ` i r . } i G t e r a I t s s d c 3 n f [ , ^ i " l o c w t " B f e j f o E r e r n ( e : o " 0 { g i 4 p , ^ b h i t c a e y s s f r n T g s q c t u s / r , , : e " t 1 s o l r h p a ( . o r o ( e . h ( r s / : n l , i " ^ o d u ( p r p j n o m } r t f u P u l i r a { d o , 0 l c e a l e a s ( m e S r r a r . o d " m : n . s a , p i r r o d " f q e o l r l s n m g e ^ 1 ^ r i c a n a " @ r : r m ) a . e ? . r : " 1 2 0 d U a $ m ( t n / o v ; m s a . n d 3 _ . 5 . : r t { s ) a e a m R e U s e r a i m 0 a 2 " 1 l i a ) ; ) x p e r R . a c c i " , l " , 2 t , o c , ; t p " q S L g r h c . , u l , 5 r n c / / n u e e c P e a s " " u { / e s a e e s t h a s c v e , , e j s e p x s s ( P r s . e r , s s r i t t i " a a T j r : o T v / - ) o f r m o p s 3 n o e a a n i a s k / i 0 " k r u u { ( l m . e a o , , e " t t a t s g n p n t n ; h h u e . e ; i : e } / " t r g t / x ` [ ; h [ e ( v 2 t , .

Overview I confirmed the workflow for processing Dataverse data with Archivematica, so here are my notes. Background Archivematica provides a feature to input data from Dataverse. https://www.archivematica.org/en/docs/archivematica-1.17/user-manual/transfer/dataverse/ I learned about this feature at the following lecture, so I decided to try it out. https://www.kulib.kyoto-u.ac.jp/bulletin/1402322 Dataverse I used the Demo Dataverse that was also used in the following article. I uploaded the following data. https://demo.dataverse.org/dataset.xhtml?persistentId=doi:10.70122/FK2/IHQZL3 From here, download both the image data itself and the JSON data. Go to the Metadata tab and select JSON from Export Metadata. ...

Overview This article describes how to authenticate with GakuNin RDM using Nuxt 3 and @sidebase/nuxt-auth. Demo App https://nuxt-rdm.vercel.app/ Repository https://github.com/nakamura196/nuxt-rdm Notes Initially, the following warning was displayed. AUTH_NO_ORIGIN: No origin - this is an error in production, see https://sidebase.io/nuxt-auth/resources/errors. You can ignore this during development Therefore, based on the following reference: https://auth.sidebase.io/resources/error-reference I configured it as follows, which resulted in an error. a } u , t b h a : s e { U R L : p r o c e s s . e n v .

Overview I had the opportunity to connect GakuNin RDM and figshare, so this is a note for reference. Work on figshare Create a folder to be linked with GakuNin RDM. First, create a project. In the following example, a project called “My First Project” is created. It appeared that linking with GakuNin RDM could be done on a per-project basis. Configuration on GakuNin RDM Select the project created on the GakuNin RDM side (in this case, “My First Project”). ...

Overview This is a memo on using GakuNin RDM from Next.js. Background In the following article, I introduced how to authenticate with GakuNin RDM using NextAuth.js. As an extension of this, I prototyped a Next.js app that loads data from GakuNin RDM. Demo This is limited to those who can use GakuNin RDM authentication, but you can try it from the following link. https://rdm-app.vercel.app/ For example, below is a page for viewing the list of connected storage. ...

Background These are notes on how to upload files and perform other operations using the GakuNin RDM API. References The following article explains how to obtain a PAT (Personal Access Token).

Method I created the following repository using nbdev. https://github.com/nakamura196/grdm-tools The documentation can be found here. ...

Overview This is a note on how to connect GakuNin RDM with Amazon S3 and process files with Archivematica. https://rcos.nii.ac.jp/service/rdm/ Background In the following article, I described how to use Amazon S3 as a processing target in Archivematica. This allows you to upload files and folders to a specified bucket and use them as processing targets in Archivematica to create AIPs and DIPs. However, this approach required creating an IAM user for each project member. ...

Overview While learning how to use Zenodo, I tried registering some materials, so this is a memo of that process. The DOI assigned to the registered material is as follows. https://zenodo.org/doi/10.5281/zenodo.12508032 DOI Regarding DOIs, there are ones that provide access to the latest version and ones assigned to each version. The DOI above is the former. Version 1 is as follows. https://zenodo.org/doi/10.5281/zenodo.12508033 For more on versioning, please also refer to the following article. ...
