Questionable media type for .lottie: application/zip+dotlottie vs application/dotlottie+zip

[trikadin]

Hi,

I noticed that mime-db currently lists the media type for .lottie files as application/zip+dotlottie. I believe this is reversed and inconsistent with common structured syntax suffix usage. The more correct form should be application/dotlottie+zip.

Rationale:

• .lottie files are ZIP archives with a specific internal structure and semantics.
• According to RFC 6838, structured syntax suffixes describe the underlying representation format (e.g. +zip, +json, +xml).
• In this case, zip is the representation, while dotlottie is the specific format layered on top of it.
• The current value suggests that dotlottie is a generic syntax suffix, which it is not.

I’m aware that application/dotlottie+zip is not currently registered with IANA. However:

• The +zip suffix is registered and widely used.
• Other media types commonly follow this pattern even prior to (or without) formal registration.
• This would align better with existing conventions and developer expectations.

Please let me know if there’s a specific reason for the current ordering, or if changing this would be acceptable.

Thanks for maintaining mime-db 🤍
