Re: Suggestions on high-level API - perhaps a meeting next week?

+1

A high-level API is also perceived to be the only kind of API that is usable by the majority of web developers. I agree we should not put this off to long.

Cheers,

David

As such, I think that before re-opening this item - which may be tricky as mentioned Ryan - we should try to finalize what we have started, meaning a stable low level API. Having said that, I see no problem for having a call dedicated to discussing qualities of the high level APIs you have mentioned, in order to build our common background. Lets scheduled this topic for one of our Monday conf call after our next F2F meeting somewhere mid-Nov.

It seems the main feedback we have from the general public is that a 
"high-level" API is necessary. Although in our original survey we had a 
slight majority in favour of the low-level, I think it would disappoint 
the people watching this work if we did not have a very "drafty" 
high-level API included in the next Working Draft.

To stabilize the low-level API would mean to go through all the open 
issues. I think having another two months to go through those open 
issues would be great, but we should reserve some meetings for a 
high-level API discussion. We may want to introduce the topic sooner 
rather than later.

And yes, +1 to having the high-level API be essentially an API for the 
JOSE formats.

    cheers,

The only way to replace the footgun is to do the crypto for them, and if you're going to do the crypto for them, it needs to be interoperable between user agents. I think JOSE's message format does this much better, in terms of public engagement and in addressing the cryptographic concerns, that it may be suitable to instead look at the high level API as perhaps simply an API for JOSE.
