[Wpack] About content-based origins

[Martin Thomson <[e-mail]>]

Ted's note prompted me to send a much-belated announcement (sorry folks, I forgot).

The draft is here:
https://tools.ietf.org/html/draft-thomson-wpack-content-origin-00

A nicer version here:
https://martinthomson.github.io/wpack-content/draft-thomson-wpack-content-origin.html

This approach could a dramatically different approach to addressing the use cases set out in our charter.

In short, this aims to address the core question of how offline content might *ultimately* be attributed to a web origin in a fundamentally different way.  There are two key concepts:

1. Content is given its own origin, using a new system for identification.

2. A target origin can "accept" content and state from one of these new origins.

There are a lot of details here (read the draft), but the major advantage I see is that you don't have to make an offline decision about authority, and that means you can be offline for much longer (lifting the 7 day limit).

What it does have in common with signed exchanges approach is the need for a bundling format, but in its current form it is less dependent on the details of the format.  That might allow that to be simpler, but I'm sure that the need to mint new identifier types will more than make up for any slack there.

The draft is quite rough.  I'm sure that it has the remnants of a few bad ideas still hanging around.  Ask questions if you think something is unclear.
