[andrew-jameson]

Background

Develop an MVP solution for parsing FRA type 1 data files using the existing functional approach. This will involve validating and storing the parsed data for further use in model #3401.

Acceptance Criteria

• FRA type 1 data files can be parsed, validated and stored for use in model from Create model and schema for WOTE data and parser errors in TDP #3401
• Testing Checklist has been run and all tests pass
• README is updated, if necessary

Tasks

• Create lean functional approach to mimic parse_datafiles()
• Reusing existing RowSchema/Field classes, alterations as needed
• Create schema definition for file that we want to parse
• Run Testing Checklist and confirm all tests pass
