          <datacite:description descriptionType="Other">現在，国立保健医療科学院(NIPH)では，国立情報学研究所(NII)が運用する研究データ管理基盤のGakuNin RDM(GRDM)を利用することによる研究基盤の整備を行っている．近年，学術認証フェデレーション「学認(GakuNin)」を利用した学術サービスが拡大している．学認は，大学や研究機関が相互に信頼する認証連携の仕組みであり，参加機関の研究者はGRDMなど，学認のService Provider(SP)を自機関IDにて利用できる．NIPHでは，学認の未参加機関やGRDM未対応機関に所属するユーザや，対応済みの機関であっても，利用対象者に該当しない研究者との研究データの共有が課題となっている．最近，NIIが研究開発を担っているOrthrosのゲストアカウントを利用することによる共同研究者のGRDM利用の試験提供が開始された．この研究では，NIPHの共同研究者におけるOrthrosゲストアカウント試験利用結果と，その際に抽出された課題を報告する．</datacite:description>
          <datacite:description descriptionType="Other">Currently, the National Institute of Public Health(NIPH) is establishing its research infrastructure by utilizing GakuNin RDM(GRDM), the research data management platform operated by the National Institute of Informatics(NII). In recent years, academic services utilizing the academic authentication federation “GakuNin” have been expanding. GakuNin is a mutual trust authentication federation mechanism among universities and research institutions. Researchers from participating institutions can use GakuNin Service Providers(SPs), such as GRDM, with their home institution ID. At NIPH, sharing research data with users from non-participating institutions or institutions not yet compatible with GRDM, or even with researchers from compatible institutions who are not designated as eligible participants, has been a challenge. Recently, NII was permitted to conduct a trial offering GRDM access to collaborative researchers using Orthros guest accounts, which NII is developing. This study reports on the trial use of Orthros guest accounts by NIPH collaborative researchers and identifies challenges encountered during this process.</datacite:description>
