# Create your models here.

# You are to develop a simple media catalog functionality. All media in the catalog
# has (at least) the following properties:
# ● Media Title
# ● Artist (Creator)
# ● Publisher (Provider)
# ● Originating Country
# ● Genre (Category)
# ● Publishing Date (different from when media was added to catalog)
# ● “Usual” data modelling properties likeID, timestamps, user id creating/updating

# Media Catalog Administrator can search media items based on genre, category, etc.
# Administrator then select desired media and assigned to either specific user,
# group of users or make it available for all users.
# When assigning media to users (publishing) the expiry date can be set by Admin.
