Open Parser accepts the input fields that you define in your parser grammar. For more information, see Header Section Commands.

If you are performing culture-specific parsing, you can optionally include a CultureCode field in the input data to use a specific culture's parsing grammar for a record. If you omit the CultureCode field, or if it is empty, then each culture listed in the Open Parser stage is applied, in the order specified. The result from the culture with the highest parser score, or the first culture to have a score of 100, is returned. For more information about the CultureCode field, see Assigning a Parsing Culture to a Record.
