CWR record types, field by field

Every line in a CWR file is a fixed-width record whose first three characters declare its type. These pages document each layout field by field — positions, sizes, formats, and what each field means — generated from the same spec tables the validator runs on.

• TRL — transmission trailer
• NWR / REV — work registration
• SPU / OPU — publisher
• SPT / OPT — publisher territory
• SWR / OWR — writer
• SWT / OWT — writer territory
• PWR — publisher for writer
• ALT — alternate title
• AGR / TER / IPA — agreements
• ACK / MSG — society response
• REC — recording detail
• PER — performing artist
• ORN — work origin
• EWT / VER — excerpts and versions
• COM — composite component
• INS / IND — instrumentation
• ARI — additional related information
• XRF — work identifier cross-reference
• Non-Roman alphabet records

Two free checks for your CWR file. Is the file correct? Every record, share and control total against the spec, each problem on its exact line. Do its writers match their registrations? Every writer cross-checked against public registration data, including works registered under another spelling or IPI. Nothing stored: check a file at cwrcheck.com.
