boolean¶

The boolean type matches only two special values: true and false. Note that values that evaluate to true or false, such as 1 and 0, are not accepted by the schema.

Language-specific info:

Python

Ruby

In Python, "boolean" is analogous to bool. Note that in JSON, true and false are lower case, whereas in Python they are capitalized (True and False).
