Categorical Attributes

Each key-value defining a categorical attribute should have the following structure:

• key: a short string that serves as the identifier for the attribute
• value: an object that should have the following keys:
  • description: a human-readable string describing the attribute to a labeler.
  • choices: a list of strings or LabelDescription objects corresponding to the categorical choices.
  • type (default category): a string describing the type of attribute. Must be category for categorical attributes.
  • conditions (optional): a JSON that describes the conditions under which this attribute should be collected.
  • allow_multiple (optional): a boolean value, if true, allows multiple values to be selected. The response will be an array of values.
