The OAuth work has successfully built a perfectly reasonable syntax and protocol for exchanging identity and attribute assertions, and that's fine. What it hasn't done is opened up the world of Identity Provision, but that's not a technical problem. OAuth flowed out of OpenID back in the day. Th

Speaking for myself, I have considerable concern about Turing-complete programming languages starting to emerge inside scope strings, which I think is probably a symptom of bad engineering. I really like the idea of specifying the scopes you’re going to ask for at registration time, and if that al

Not deeply acquainted with the Flickr scenario, but it occurs to me to ask: If OAuth 1.0 is working well for them, why don’t they just keep using it? I.e. if there’s already a good solution in place for people who require secure authn/authz over insecure channels, why would we go the extra work of

A DELETE is an http request that asks the server to delete something. We probably would want to avoid writing a requirement into the standard that the server has to comply. So you get back a 204 if it worked, a 404 if there is no such registration, a 403 if there is but the server declines to del

That might have happened had there been some free high-quality ASN.1 software, instead of slow buggy parsers that cost $50K to license. It’s always seemed to me that one reason XML took off so fast is that there were fast robust open-source parsers in C and Java before the spec was even finalized.
