Re: [OAUTH-WG] Dynamic Client Registration: IPR Confirmation

May/June of 2010 OpenID Connect and OpenID artifact binding merged to crate a spec based on top of OAuth 2.

Aug 2010 there was a ID called "OAuth Dynamic Client Registration Protocol" http://tools.ietf.org/html/draft-oauth-dyn-reg-v1-00 that included discovery (XRD) published by Eve, Maciej and Chriatian that was used by UMA.  

The early model largely used a pull model to validate the identity of the client registering. eg The AS pulled down a file of JSON in a effort to validate an identity for the UMA client.
It did have amongst several methods one that was a client push.

Around May of 2011 I did the initial Connect dynamic client registration posting a JSON object with values to a registration endpoint and getting back a client_id and secret.
We went back and forth several times on Key value vs JSON requests over the spec's development.

In there initial forms it is true that the client winds up with a client_id and client secret, but I don't think they were in any way wire compatible.
Looking at it the parameter name "redirect_uri" (taken from the OAuth spec is the same but the values are different one is a string and the other an array of strings.

At a Connect WG meeting at IIW (fall 2011) with Eve who I believe is or was a Connect WG member from PayPal and I came up with making the registration endpoint OAuth protected with an initial acces token to provide the possibility of identifying the registrant, as that was part of the UMA use case.   That enabled UMA to I believe drop the pull registration and align more with Connect registration, as well as adopt Connect semantics in some other parts of UMA for compatibility.  

That was added to the Connect in Oct/Nov 2011.  There were lots of other things like client secret key rotation that were in the Connect version but were taken out and moved to a management draft in the end and not put in the final connect version.

In May of 2012 Justin, Eve, Thomas & Mache published a 00 ID that was a copy of the UMA .

That was updated over I think 18 versions to get to what we have now.   Including input from Phil/Tony on software statements.

So in the way of the IETF a number of groups with initial documents covering similar use cases came together in a working group and a document was produced that satisfied multiple use cases so that adoption and interoperability of OAuth 2 could happen.

Yes one of the inputs is the 00 draft that was used by UMA before I think they migrated to the connect version.   I don't know what the UMA specs currently reference.

I think referencing the earlier ID  and giving credit to the earlier authors is fair.

(I doubt that anyone will assert IPR about a parameter name change, so I suspect that instance was innocuous.)  When some of the same people were in two working groups doing highly related things, I suppose some of that was bound to happen, despite the best of intentions.  However, it's still my assertion that the core inventions in Connect Registration were independently developed, syntax tweaks made later for compatibility reasons aside.

People who know me know that I'm all in favor of giving credit where credit is due.  I'd thought that all the UMA content had been replaced, but if I'm wrong about that, so be it.

And it's true that the UMA draft predates both of these by a fair whack and at the very least provided inspiration in how to accomplish this task, and in fact draft -00 was a straight copy of UMA. As Mike mentions below, draft -01 (when I took over the editor

It's fairly clear if you look at the document history that there was a lot of back and forth. The JSON formatting in the IETF draft, for example, exists in -00 and came from UMA, was switched to form encoding from in -01 (from OIDC), and with lots of discussion here in the WG (both before and after the
> change) was switched back to JSON in -05. At that time, there was a discussion in the OIDF working group of whether to adopt the JSON formatting as well in order to maintain compatibility, and OIDF decided to do so. There were other instances where parameter names and other ideas began in the IETF and moved to OIDF's spec, like changing "issued_at" to the more clear "client_id_issued_at". These were breaking changes and not entered into lightly, and I was there for those discussions and still contend that OIDF made the right call.

It's perfectly fine with me that the OIDF represent itself and its documents how it sees best. But it's not OK with me to discount or misrepresent the history and provenance of the ideas and components of this IETF document in the IETF and I'd like to include the modified statement I posted below in the introduction text of the next revision.

>> I disagree with one aspect of Justin's characterization of the history of the spec and have data to back up my disagreement.  The OpenID Connect Dynamic Registration Specification was not based on draft-ietf-oauth-dyn-reg-00 or the UMA specification.  It was created independently by John Bradley in June 2011 based upon OpenID Connect working group discussions that predated draft-ietf-oauth-dyn-reg-00, and for which there are working group notes documenting the OpenID Connect working group decisions prior to the IETF -00 draft.  Yes, there's plenty of evidence that the IETF -01 draft copied text from the early OpenID Connect draft (including in the change history), but the Connect authors were careful to follow the OpenID Foundation's IPR process and not incorporate contributions from third parties who hadn't signed an OpenID IPR Contribution Agreement stating that the OpenID Foundation was free to use their contributions.  (This fills the same role as the IETF Note well, but with a signed agreement, and ensures that all developers can use the resulting specifications without IPR concerns based on IPR that may be held by the contributors.)  The OpenID Connect Dynamic Registration draft didn't copy from the UMA draft or the IETF draft derived from it, so as to maintain the IPR integrity of the OpenID document.  The copying all went in the other direction.
