The default is db.sqlite. You should carefully read and check all of settings.py.DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}Next, run the database build commands:python3 manage.py makemigrations
python3 manage.py makemigrations preservation-database
python3 manage.py migrateYou should then have a working database into which you can import new preservation data.Archive NotesInternet ArchiveThe Internet Archive gives a KBART file for the Keepers Registry that we use as a primary ingest source:https://archive.org/details/ia-keepers-registry-kbart. However, this source is not the total coverage of the Internet Archive. However, sadly, the Internet Archive snapshots do not contain external identifiers and the container-level snapshots do not present coverage extent. While it is possible to download the entire 217GB FATCAT database snapshot, this will not be viable for many users. We have therefore stuck with the KBART file that Keepers uses. Extent of coverage in the Internet Archive may, therefore, be under-reported.CreditsDjangofor the ORM.Gitfrom Linus Torvaldset al..gitignorefrom Github.Richfrom Textualize.© Crossref 2023
