Solid Project · Data sovereignty and access grants (Solid-OIDC) SIGNET support: Architectural alignment — the consent pattern

What it is

Solid is the data-sovereignty project originated by Sir Tim Berners-Lee: data lives in stores controlled by its owner, and other parties access it through explicit, revocable grants rather than by receiving copies. Solid-OIDC is the ecosystem's authentication specification, binding OpenID Connect to Solid's model of identity and access.

The specifications are maintained by the Solid community. Official reference →

How SIGNET supports it

Solid sits in SIGNET's architectural alignment tier, and its influence is one of the model's design principles: data sovereignty is explicit. SIGNET separates an assertion from the right to access the data behind it, and assumes no central data warehouse.

The alignment is concrete in two places. The canonical Consent object expresses a Solid-style access grant as data: the right of a named party, for a stated purpose, for a bounded time, to access data held by another party. And the Document object carries an accessGrant reference, so "a document exists" and "you may read it" are distinct, governable facts. Together they make access a first-class, auditable part of the procurement record rather than an implementation detail of whichever platform holds the file.

Precision on scope: the alignment is with Solid's access-grant and data-sovereignty pattern, expressed in the CDM. SIGNET does not normatively specify an authentication protocol; Solid-OIDC is the natural companion for implementations that adopt the full Solid stack, but conformance does not require it.
