Chat Log

00:03:39	Chris "cdata" Joel @ Subconscious:	Irakli is kind of breaking up for me
00:03:42	Boris Mann:	@irakli is breaking up / can't hear?
00:04:12	Irakli Gozalishvili:	my connection is pretty bad, maybe hugo could fill that in plz
00:04:21	Philipp Krüger:	He did!
00:06:50	Boris Mann:	Cookbook!
00:07:11	Hugo Dias:	😆
00:10:26	Irakli Gozalishvili:	capability marketplace 😛
00:11:44	Chris "cdata" Joel @ Subconscious:	Cookbook = ways to use the spec as is to achieve a goal

Is it also a place where "recipes" that require *changes* to the spec can go?
00:12:09	Brooklyn Zelenka (@expede):	Great idea 💯
00:12:24	Philipp Krüger:	Hmm. That seems like a case for github discussions on the spec repo, Chris
00:13:04	Chris "cdata" Joel @ Subconscious:	Okay, SG
00:13:36	Philipp Krüger:	Or maybe even issues. I think that's what we've used them for so far.
00:14:28	Hugo Dias:	https://hackmd.io/@gozala/ucan-invocation notes on why we support multiple invocations but restrict each invocation to one capability. @expede
00:15:19	Boris Mann:	@philipp yes we’ll use the Discussions but a capability marketplace / recipes would be published on the community website as resources / docs
00:15:38	Philipp Krüger:	Yes absolutely.
00:15:54	Philipp Krüger:	I was answering "discussions/issues" for "recipies that need spec changes"
00:19:54	Chris "cdata" Joel @ Subconscious:	I hate Slack
Matrix is cool but hard to use on my phone
Keet was born yesterday
Long live Discord!

:D
00:20:24	Irakli Gozalishvili:	oh please I don't to install another chat app
00:20:33	Brooklyn Zelenka (@expede):	👆THIS
00:20:42	Philipp Krüger:	I would be fine with slack, if they had a good account system... maybe something user-owned... maybe using something like UCAN :P
00:20:57	Brooklyn Zelenka (@expede):	😉
00:21:11	Philipp Krüger:	Clearly we need to convince slack, discord and matrix to adopt UCANs as an account system
00:27:40	Daniel Holmgren:	https://github.com/bluesky-social/adx/tree/main/packages/awake
00:28:29	Philipp Krüger:	https://github.com/ucan-wg/awake
00:31:34	Philipp Krüger:	https://magic.link/
00:32:38	Irakli Gozalishvili:	can someone link to passkey ? I'm not sure what that is
00:32:46	Brooklyn Zelenka (@expede):	Passkey is FIDO2
00:32:54	bengo:	https://datatracker.ietf.org/wg/gnap/documents/
00:32:57	Brooklyn Zelenka (@expede):	But Apple's branded implementation coming out later this year
00:33:00	Philipp Krüger:	https://developers.google.com/identity/fido
00:33:10	Irakli Gozalishvili:	got it thanks
00:33:57	bengo:	also see "Authorization Capability Request" https://w3c-ccg.github.io/vp-request-spec/#authorization-capability-request
00:34:18	Hugo Dias:	https://fidoalliance.org/apple-google-and-microsoft-commit-to-expanded-support-for-fido-standard-to-accelerate-availability-of-passwordless-sign-ins/
00:37:27	bengo:	It's this WG https://identity.foundation/working-groups/secure-data-storage.html
00:37:45	Mikeal Rogers:	More of a high level meta-comment: if you look at the “Terminology” section of the spec, each one of these 2.x sections is also another branch of extensions to the protocol related to the term. might help organize the many threads starting around the project.
00:38:00	Mikeal Rogers:	https://github.com/ucan-wg/spec#2-terminology
00:38:31	Brooklyn Zelenka (@expede):	Yes absolutely
00:39:12	Chris "cdata" Joel @ Subconscious:	https://twitter.com/Iinux/status/1552164523049623552
00:39:43	bengo:	"GNAP Token Format Registry" - want UCANs in there? zcaps are in there https://www.ietf.org/archive/id/draft-ietf-gnap-resource-servers-02.html#section-6.1.2
00:47:53	Brent Shambaugh:	fwiw, I know someone who works on wasm: https://github.com/yurydelendik . 
00:49:16	Chris "cdata" Joel @ Subconscious:	I like them except for some reason notifications don't hit my inbox for whatever reason.. which is probably my fault.
00:49:41	James Walker (@walkah):	Is there also a todo to transfer rs-ucan to the ucan-wg org?
00:50:06	Brooklyn Zelenka (@expede):	@cdata 👆🙏
00:50:36	Chris "cdata" Joel @ Subconscious:	How users configure loading a WASM DRACO decoder for <model-viewer>: https://modelviewer.dev/examples/loading/#dracoSupport
00:53:29	Brent Shambaugh:	I have an implementation question. 
00:54:19	bengo:	maybe even at? https://twitter.com/RadxChange/status/1550584960054005761
00:57:58	Chris "cdata" Joel @ Subconscious:	@walkah yes

https://github.com/cdata/rs-ucan/issues/15


00:58:32	James Walker (@walkah):	👍
01:00:00	Brent Shambaugh:	I'm listening, this is helpful
01:00:34	Irakli Gozalishvili:	bye

Notes

[bmann]

I don’t want to spend a lot of time on it, but @hugomrdias brought up graduating UCAN to its own chat server.

[bshambaugh]

I'm joining the call to listen in. I have some ideas about how it might apply to my use case and might want to briefly touch on that, but what I say may be predictably fuzzy as I am still at the ideation/research stage.
