$schema
$ref

What is the reason for the 4 symbol? Is it signifying they reference
other schemas? Or that something external to the schema is being
referenced?

The $ is a character like any other in a JSON string. I guess it has
been picked as special for convenience...

It should be noted though that:

{
    "$ref": "whateverurihere"

}

can be viewed as a JSON Reference, which is specified (don't have the
link handy atm).
