A DOI can be reserved for your research output, and its identifier can be provided in advance.
For research outputs made available through the UTokyo Repository, you can select either a JaLC DOI or a DataCite DOI when depositing your work.
However, if you need a DOI to be assigned in advance, such as when submitting a manuscript to an academic journal, we recommend choosing a DataCite DOI through Self Archive.
Comparison of DOI Types:
| JaLC DOI | DataCite DOI | |
|---|---|---|
| Link destination after public release | The item page in the UTokyo Repository (https://repository.dl.itc.u-tokyo.ac.jp/) | The item page in the Self Archive portal (https://r.dl.itc.u-tokyo.ac.jp/esploro/ ) |
| Timing of Assignment | Assigned after the repository publication process is completed. It typically takes approximately 1-2 weeks after your request. |
Assigned immediately via the Self Archive submission form.* |
* A reserved DOI issued throgh Self Archive will not become active until the content is made publicly available in the portal.
* For more information about DOI types, please see "About DOI".
