The W3C then laid the foundations of the Web with the development of HTML 4 and XML at the end of the last century.

excerpt: >
The mission of the W3C Credentials Community Group is to explore the creation, storage, presentation, verification, and user control of credentials. We focus on a verifiable credential (a set of claims) created by an issuer about a subject—a person, group, or thing—and seek solutions inclusive of approaches such as: self-sovereign identity; presentation of proofs by the bearer; data minimization; and centralized, federated, and decentralized registry and identity systems. Our tasks include drafting and incubating Internet specifications for further standardization and prototyping and testing reference implementations.

* [CCG updates to cgbot and scribe-tool](https://lists.w3.org/Archives/Public/public-credentials/2021May/0169.html)  Manu Sporny (Sunday, 30 May)
New CCG infrastructure features:
- Auto-presence - No one is required to present+ themselves any more. The cgbot does it for us now, saving our feeble sausage fingers from being over exerted.
- The Ryan Grant, Who We All Know And Love, Would Like To Know Where The Raw Transcripts Are Feature - When the cgbot closes out the meeting, it will let everyone in IRC know where the raw transcripts, audio, and video files are so anyone can download them and/or remix them to spread CCG propaganda. This will hopefully also save Heather from having to document yet another piece of tribal CCG knowledge.
- The You Exist Even Though You're Not in people.json Feature - When someone is present+'d, which is anyone that joins the call now thanks to auto-presence, that person will show up in the attendees list. This achieves two things 1) the poor minutes publisher can update the people.json at their leisure instead of being blocked by it whenever a new person shows up to a call, and 2) we get a more accurate record of attendees.
- The Fellow Jitser Invisibility Decloaker Feature - If you join the meeting with a new browser, or in Incognito mode, and you change your name from "Fellow Jister" to your preferred name, you never show up in the attendee list. People that change their names now show up in the attendee list. If you want to stay pseudonymous just give yourself an unrecognizable name... like "Robot Overlord".
