I believe that if we solve the "domain" issue -- which definitely needs solving -- we automatically also have solved the "within domain" issue, in which case no separate solution for the "within domain" issue is needed and may actually be counter-productive. On May 14, 2007, at 10:29, Dick

The issue you bring up is a separate issue then the motivation for recycling identifiers by large OPs. Your point is how does a user transfer from one identifier to another. The issue at hand is the scarcity of namespace. -- Dick On 14-May-07, at 8:48 AM, Johannes Ernst wrote: > These seems

These seems to be an assumption on this thread that - identifiers at the same domain name get recycled often (e.g. example.com/jim) - domain names don't get recycled often (e.g example.com itself) I would suggest that any proposed solution needs to be able to deal with domain names as well t

Hi Dick, I'm very glad to see that we're making progress in resolving the OpenID recycling issue. It would seem to make sense to embed the fragment into the document referenced by the OpenID, however in the interest of keeping the OP discovery implementation simple and robust, I'd be in favor of

Dick, This is definitely an interesting proposal. However, it only attempts to solve the recycling problem, whereas canonical IDs would solve this and several more. Will this break existing OpenID 1.1 RPs? Which ones? Is this going to be an issue for them? As far as I can tell, this would b

I had the good fortune of discussing URIs, URLs, fragments and the recycling issue with a number of smart W3C people at WWW2007 and they did not respond with horror at the concept of using fragments to recycle identifiers. Given this is a requirement for large OPs, here is a proposal. A num
