This was done because, in CBOR, there is a way to distinguish between a string 
and a URL.  This is lacking in JSON.  I believe that the ability to not have to 
determine this heuristically is a good thing.

Subject: Re: [Ace] CWT - Audience

 

My guess is that this is an early mistake that has not been noticed, it has 
been like this from the first draft.

I think the correct thing would be to change it so that CWT reflects JWT.

Hi all, 

 

in https://datatracker.ietf.org/doc/rfc7519/?include_text=1 (section 4.1.3), 
“aud” is defined for JWT as being an array of case-sensitive strings, or a 
single string.

 

In 
https://datatracker.ietf.org/doc/draft-ietf-ace-cbor-web-token/?include_text=1 
(section 3.1.3), “aud” is defined for CWT as being like in JWT, but “the value 
is of type StringOrURI”. 

 

I was wondering how we arrived at this point where the CWT and the JWT differ 
in this regard. 

 

Ciao

Hannes
