I was wondering if anyone happens to know a way to extend/overload the

STANDARD_KEYS

list and

Schema

data class within a tap/loader

tap.py

or

client.py

? I want to use the JSONSchema keywords

contentMediaType

and

contentEncoding

that were introduced in Draft 7 but noticed they don't show up in

schema messages

until they are added to the

STANDARD_KEYS

list and

Schema

data class found in

singer-sdk\_singerlib\schema.py

. I put some links to more info in a reply to this question.
