Looks like fixtures can help.
Reference: Providing initial data for models. Version 2.1 documentation: https://docs.djangoproject.com/en/2.1/howto/initial-data/

Documentation (by Pranav) that maps App Store DB to OBR:

https://docs.google.com/document/d/1GcbkXuvlNumh-ir0rhPtKLdrTrLDlpB6LSc7ft6uohk

Branch: https://bitbucket.org/svallapu/appstore/branch/IGBF-1521

Fixture:
JSON file Name : /appsDB.json (root folder). It is also attached to this issue.
To Load Data (command): python manage.py loaddata appsDB.json

Updates/ Changes :
1. Added new symbolicname field to the apps model (models.py)
2. Migrated the new changes (symbolicname) to the apps table in the database.
3. Created superuser to access the Admin
--> python manage.py createsuperuser
--> Enter username and password to access Admin page
--> Admin Page Link localhost:8000/Admin
4. Copied the records from repository.xml to local database.
5. Created fixtures using existing data
--> Dump Data: python manage.py dumpdata appname > fileneme.json
--> Load Data: python manage.py loaddata <filename.json>
6. Deleted django.wsgi (Recommended by Pranav)
7. Replaced path with re_path for the links to accept regular expressions. (wherever needed)
8. Changed the link from underscore to hyphen (Important). (It avoids crashing when using hyphens in the URL)
->re_path(r'^(?P<app_name>[-\w\d]+)' use this regex to accept hyphen ("") in the URL.
9. Decoded base64 for the details field. (Only allows base64 input, for now, didn't convert markdown to HTML)

Fixture.
