Details

In the physical representations of data where boolean values are represented with strings, the values set in trueValues and falseValues are to be cast to their logical representation as booleans. trueValues and falseValues are lists which can be customised to user need. The default values for these are in the additional properties section below.

The boolean field can be customised with these additional properties:

• trueValues: ["true", "True", "TRUE", "1"]

• falseValues: ["false", "False", "FALSE", "0"]
