Help:Type Boolean

The datatype Boolean is for attributes that can only have two possible values, called truth value. You can enter "true" or "false", also 1/0, yes/no, t/f, and y/n. Other languages may provide language-specific options.

To allow two arbitrary strings, or more than two possible values (such as  -   -   -  ) use  with  to restrict the possible values. In many circumstances it may also be more appropriate to use a category instead of a Boolean.

Display formatting
By default, Boolean values will display  and   in queries. This can be changed starting with by specifying a format string to control what is displayed for the true and false values of a property.
