Re: Revocation List 2020

On the subject of revocation list, the current VC spec requires the id to be a URL. Are there plans/discussions to allow for decentralized approaches (I’m thinking IPFS but other solutions too)?

I didn’t find anything in the history since I have joined the mailing list.

Thanks

Hi All,
circulating a few questions that I had sent to Manu and that should've been shared on the thread.

Hey Mahmoud, these are all good questions for the mailing list... would you
mind sending them there?

No, there isn't any implementation of it yet, although any implementation
should more or less be the same save for some modified `type` values, IIRC.

Basically, it should be more or less a copy-paste of the Rev list 2020
implementation.

Yes, it should... feel free to raise a PR to do that, or I'll get around to it
the next time I'm in that spec (probably not any time soon).

Yes, if by "publish a new list" you mean, Example 3:

https://w3c-ccg.github.io/vc-status-list-2021/#example-3-example-revocationlist2021-credential [w3c-ccg.github.io]<https://urldefense.proofpoint.com/v2/url?u=https-3A__w3c-2Dccg.github.io_vc-2Dstatus-2Dlist-2D2021_-23example-2D3-2Dexample-2Drevocationlist2021-2Dcredential&d=DwMFAw&c=QYtPDevkFwe0D4WYMQB04ZDjCuesXtU6kfumrUDz_K4&r=pYB7rZbKH5pgH0VvhxFGyRpoIQu5ArITYzXqjW4SH04&m=65KMpPqF9JRqm2LZ2XJn-ZuhNUzVJy_I7kxlJWFSUvc&s=TbZyLRKAtz7jG2ag0Rm9OgAzZpdCCS8ubTK0DMtunJM&e=>

> or is the general idea to "update" the list with new credentials?

Hmm, also this. The thing that doesn't change is:

The initial credential issued. For example:

https://w3c-ccg.github.io/vc-status-list-2021/#example-2-example-revocationlist2021 [w3c-ccg.github.io]<https://urldefense.proofpoint.com/v2/url?u=https-3A__w3c-2Dccg.github.io_vc-2Dstatus-2Dlist-2D2021_-23example-2D2-2Dexample-2Drevocationlist2021&d=DwMFAw&c=QYtPDevkFwe0D4WYMQB04ZDjCuesXtU6kfumrUDz_K4&r=pYB7rZbKH5pgH0VvhxFGyRpoIQu5ArITYzXqjW4SH04&m=65KMpPqF9JRqm2LZ2XJn-ZuhNUzVJy_I7kxlJWFSUvc&s=99dhQvzUpJoDqup2irzrjiaTBu1GbjYazMCsgdLgPX0&e=>

The thing that DOES change is the status list. For example:

https://w3c-ccg.github.io/vc-status-list-2021/#example-3-example-revocationlist2021-credential [w3c-ccg.github.io]<https://urldefense.proofpoint.com/v2/url?u=https-3A__w3c-2Dccg.github.io_vc-2Dstatus-2Dlist-2D2021_-23example-2D3-2Dexample-2Drevocationlist2021-2Dcredential&d=DwMFAw&c=QYtPDevkFwe0D4WYMQB04ZDjCuesXtU6kfumrUDz_K4&r=pYB7rZbKH5pgH0VvhxFGyRpoIQu5ArITYzXqjW4SH04&m=65KMpPqF9JRqm2LZ2XJn-ZuhNUzVJy_I7kxlJWFSUvc&s=TbZyLRKAtz7jG2ag0Rm9OgAzZpdCCS8ubTK0DMtunJM&e=>

Thanks Manu for the feedback!

Hey Nikos:

Manu is going to be at the DIF Interoperability WG Wednesday doing an "Ask me anything" session on SL-2021 & RL-2020.  If time zones allow, I'd recommend coming and asking him to say a few words or listening to the recording?  I'll post a link back to this thread after.
