Metadata consistency

This article is a part of Believe's Audio Content Guidelines.

All mandatory fields must be filled: track titles, composers, label...

Correct format and number of characters for codes (UPC, ISRC, EAN…) is required, or a blocking error during ingestion will occur. The correct format for genre and language is ensured by constrained lists during ingestion.

For Jazz releases, the detailed contribution of each performer must be added.

For opera / western classical genres specific fields must be filled: movement, n° opus, tonality, etc.

Release duplicates. A release is considered a duplicate if:

• it has already been delivered to a store
• there is already a release with the same ISRC or UPC in the database

Track duplicate in a release. Believe’s system doesn’t accept two tracks with the same metadata in one release.

Metadata Language: The track title language must match with the manually entered language metadata, and the casing for this language must be respected. 

Lyrics Language:  The appropriate audio language must be set in the metadata at the track level

Language must match the language spoken or sung in the audio. Nonlinguistic content must be set as instrumental. Note: For lyrics in some Indian content, Original Metadata Language must be set to English.

Original Release Dates / Accuracy: Albums, tracks, and music videos must be delivered with the release date of their original issue, digitally or physically, regardless of version or country or region of origin
