 A Django app to properly model the [DataCite Metadata Schema](https://schema.datacite.org/) in a relational database, with full integration into the Django admin interface. The app is *slightly* opinionated in a way to make it better usable as a DOI registration database. Names (`creators` and `contributors`) and identifiers (for the resources, but also for `alternativeIdentifiers` and `relatedIdentifiers`) are stored in separate database tables and can be reused for different resources.
