[Openid-specs-risc] RISC event URIs

openid.ns values in http://openid.net/specs/openid-authentication-2_0.html#anchor4
Claimed Identifier URI in http://openid.net/specs/openid-authentication-2_0.html#discovery
                (there are plenty more in this spec)
Attribute exchange namespace at http://openid.net/specs/openid-attribute-exchange-1_0.html#anchor2
PAPE namespace at http://openid.net/specs/openid-provider-authentication-policy-extension-1_0.html#anchor3
Issuer URI at https://openid.net/specs/openid-connect-discovery-1_0.html#IssuerDiscovery
Backchannel Logout event at http://openid.net/specs/openid-connect-backchannel-1_0.html#LogoutToken
MODRNA policies at file:///C:/mbj/DSG/OpenID/MODRNA/openid-connect-modrna-authentication-1_0.html#rfc.section.4
EAP ACR URIs at http://openid.net/specs/openid-connect-eap-acr-values-1_0.html#ClaimsContents

There are plenty more.  These are just a quick subset I knew about off the top of my head.

Yes, it would be OK to put “risc” in the name.  The, for instance you might use this URI for Account Deleted:

IETF and “secevent” don’t really have a reason to be in these event names, because it’s the OpenID RISC WG defining these events, not the IETF or the SecEvent WG.

Shouldn't "risc" (the profile name) be part of the URI?

Similarly, what about "ietf" and "secevent" being part of the URI?

Can you point to some of these other specifications and URIs?

I’d suggest that RISC event names be openid.net<http://openid.net> URIs.  For instance, I’d use the event name http://schemas.openid.net/event/account-deleted for the Account Deleted event that Marius described.  That would be consistent with how other things have been historically named in OpenID specifications.

That said. It is perfectly ok for risc to use urns while the core spec specified uri.

There would just be no central event registry except within risc.

Good point, will start the discussion on the secevent list.

I think the format of these should be decided in secevent.

I think your proposal of secevents starting with “urn:ietf:params:secevent:event-type:” is one worth proposing in secevent.

"urn:ietf:params:secevent:aud-client-id:<client-id>" is clearly a secevent discussion item

"urn:ietf:params:secevent:event-type:risc:sessions-revoked" would be an event URI, the key under the "events" claim

"urn:ietf:params:secevent:aud-client-id:<client-id>" would be the aud claim, and this solves the "SET re-played as an access token" issue

Where are you thinking this is in the secevent SET Marius?

While talking about events, we should also decide how the event URI will look like for RISC.

I propose we use URN sub-delegation for "ietf" namespace (RFC 3553), something like:
urn:ietf:params:secevent:event-type:risc:all ?

Maybe instead of "event-type" in the above URNs we should use "profile"? Since "risc" above signifies a whole class of event type and not a particular one:

We can use this scheme for other RISC related URNs, like a prefixed aud:
