How do I map Batch Processor input data to a rulebase attribute?

When using csv data, if a column in a table exists which has the public name of attribute for the entity, then that column will be mapped as an attribute.

You can explicitly map a column from a csv file or database table to a rulebase attribute by specifying a mapping.

Use the xml element <attribute> in the configuration file, to specify a mapping with the following attributes:

name attribute defines the rulebase attribute public name
field attribute defines the csv or database column in which the data exists.
output attribute (optional) is used to identify the field as an output field. If not included the value will default to "false" and the field will not be used as output.

For more information, see Data mapping in the XML configuration file. See also Zero-configuration conventions for csv input for more information on default mapping of csv data.
