Re: [media-types] image/webp rfc review

Dear James,

It seems that you have taken come steps toward my wish:

> File extension(s): webp
> Macintosh file type code: UTTypeWebP com.google.webp

I am not sure what `UTTypeWebP` means (a property-list key?) but 
`com.google.webp` sounds to be an [Apple Uniform Type 
Identifier](https://developer.apple.com/library/archive/documentation/Miscellaneous/Reference/UTIRef/). 
Is that correct?

My suggestion would be that you enrich your declaration so that it 
supports interoperability for clipboard exchanges between different 
apps. For this, I believe that you have to add a uniform type identifier 
(including the “conforms to” part, declaring a parent type) and a 
windows clipboard flavour name. At best this is defined already by 
implementing applications.

I could imagine the following declaration to be sensible:

- `Macintosh Uniform Type Identifier: com.google.webp conforms to        
              public.image and to public.data.`
- `Windows Clipboard Flavour Name: WebP`

Feel free to revisit (add riff as one of the parent types?), reject, or 
consider this suggestion.

Thanks in advance.

Paul

PS: I believe that the entry `Macintosh file type code` was for the 
4-bytes code that used to be registered at Apple back then. I’ve been 
trying to push an update of the RFC6838 but haven’t yet got this to 
start.
