[mfekadu]

Alternative

• someone already had the same idea
  • There exists a package called marshmallow that seems to help with json validation while allowing us to keep snake_case in Python

[mfekadu]

Let’s definitely use Marshmallow

As a result, we will enforce JSON naming conventions for interacting with the REST API.

The scraper will need to update it’s set of column names for each scraper.
