Re: HTTP Signatures draft published at IETF

Hmm. In RFC5988, we say:

So, the default context of a request is the requested resource URI, *not* the payload of the request.

I think that's a bug, but by the spec, that's still the case. I opened:

It certainly solves the problem at hand re. a payload relation that associates a payload (originating from a browser) with the actual human of machine that instigated the payload. For example, in HTTP, one could then represent an <http://example.org/action#onBehalfOf> relation via the following triple:
