    parentFeatureName

    The name of the parent feature(s) for the column. Usually a column has one parent feature, but can have many (eg. in the case of multiple Text columns being vectorized using a shared hash space)

    parentFeatureType

    The type of the parent feature(s) for the column

    grouping

    The name of the group a column belongs to (usually the parent feature, but in the case of MapVectorizers, this includes keys in maps too). Every other vector column in the same vector that has this same indicator group should be mutually exclusive to this one.

    indicatorValue

    An indicator for a value for a binary column (null indicator or result of a pivot or whatever that value is), otherwise None

    descriptorValue

    A name for a value that is continuous (not a binary indicator) eg for geolocation (lat, lon, accuracy) or for dates that have been converted to a circular representation the time window and x or y coordinate, otherwise None
