A simple template for an (E)T(L) challenge, in Python (3.5+), designed to be completed in about 30 minutes.
Create a file named sample_message.json in the resources directory.
This can contain any pre-transformation JSON as long as it is valid JSON.
Create a file named sample_message_schema.json in the resources directory.
This should contain a valid JSON schema that you would like to validate the TRANSFORMED input JSON against.
In the utils/transform.py file's transform() function write your code to transform the input to match to the output schema.
Simply invoke python(3) -m transformer, you will be informed if your transform is successful or if it fails.
