Metadata displayed on DSPs must follow the casing conventions of the language in which it is written. These conventions apply to all public-facing metadata fields in Reprtoir, including Titles, Subtitles, Artist names, contributor roles, and Version Descriptors.

Metadata must never appear in full uppercase, full lowercase, or with arbitrary capitalization. Exceptions apply only to acronyms, initialisms, officially stylized names, or legally required branding.

Punctuation must follow standard linguistic rules. Decorative symbols, emojis, ASCII art, repeated punctuation, and typographic elements used for emphasis are not accepted unless they are part of an officially registered artist identity.

Below are the accepted casing rules for major languages used in music metadata.

🚧
Important Note for Non-Latin Scripts
Languages such as Chinese, Japanese, Korean, Arabic, Hebrew, Thai, and others do not use capitalization. DSPs expect titles written in these scripts to be delivered exactly as written, with no stylized casing, spacing, or decorative characters. When these languages are romanized (Pinyin, Romaji, Romanized Korean, Arabic transliteration), DSPs require sentence case: only the first word and proper nouns are capitalized.

English Title Casing

English titles use Title Case.

The first letter of each major word must be capitalized.

The following words remain lowercase unless positioned at the beginning or end of the title:

a, an, and, as, but, for, from, nor, of, or, so, the, to, yet.

Prepositions of four letters or fewer remain lowercase:

at, by, for, from, in, into, of, off, on, onto, out, over, to, up, with.

These words must be capitalized when they act as part of a verb phrase or function as another part of speech.
