WebID Comparison

Full Title

Comparison between various proposals for Web ID.

Context

Several proposals existing starting from Tim Berners-Lee in 2020-03-05 to rescent version from the browser folk and the decerntalized ID folk, all in the W3.

WebID 1.0

• The first proposal from Sambra, Story and Berners-Lee sought to deal with a distributed Social Web.
• A WebID is an HTTP URI which refers to an Agent (Person, Organization, Group, Device, etc.). A description of the WebID can be found in the Profile Document.
• A WebID Profile Document is a Web resource that MUST be available as text/turtle [link broken], but MAY be available in other RDF formats.
• WebIDs can be used to build a Web of trust using vocabularies such as FOAF [FOAF] by allowing people to link together their profiles in a public or protected manner.
• URI fragments (#me) support sub sets or offshoots of the profile doc which is available at the base URI.
• Supported several authentication schemes like WebID-OIDC Authentication Spec for decentralized systems.

DIF Web ID

• Basically is given by a DID which is recovered from a public ledgier system.
• Well Known DID Configuration is a DIF working group document that describes the following well-known endpoints.

Trust Token

• The Trust Token explainer from the blink (browser engine) team.
• a new API for propagating a notion of user authenticity across sites, without using cross-site persistent identifiers like third party cookies. Trust Token is built on Privacy Pass for anonymous tokens that can't be tracked between issuance and redemption.
