SWR / OWR — writer

One line per songwriter: SWR for writers you control, OWR for others. Name, IP number, role (composer, author, arranger…), society affiliations, and ownership shares.

The exact field layout — positions, sizes, and formats — is defined in CISAC's CWR specification (CWR19-1070R1), available to CISAC members and licensees. The validator implements the full layout: drop a file on it and every SWR / OWR line is parsed field by field, with problems tied to the exact characters at fault.
