The WebID is a decentralized identification standard that enables individuals and organizations to establish a unique, verifiable identity on the web. It is built upon Linked Data principles and typically represented as a URI (Uniform Resource Identifier) pointing to a publicly accessible profile document.
Authentication of the users in Welldata is based on the SOLID-OIDC specification. It defines how owners of the pods need to authenticate towards an IDP and how resource servers can verify the identity of pod owners based on that authentication. The SOLID-OIDC flow is described in detail here
The SOLID-OIDC flow is based on the OIDC flow.
In Solid each agent has a WebId associated with it. The WebId contains information on how the agent can authenticate itself. In We Are application agents are registered in the We Are IDP. This is an IDP specifically for applications, which allows applications to identify themselves. Clients are authorized via the client credentials flow to receive an access token.
The token endpoint is called with the following parameters:
client_credentials
In order to access the resource in the pod, the client needs to exchange it's token for yet another token by calling the UMA service of Inrupt.
