Solid

One-line summary: Decentralized web architecture where the user owns a pod and applications request typed access — the app is not the store.

What it is

A Solid ecosystem in which Social Agents store data in pods and grant Applications access via registries, shape-tree data registrations, access needs, and access authorizations. The Application Interoperability draft used here is a W3C Community Group Report (25 September 2025), not a W3C Standard. From 2026-08-21-autoresearch-best-architecture-for-a-rec-system-web-app.

Why it matters to interest-graph-recs

Cited alternative to a recs web app that hosts the interest graph itself: the user keeps the graph; the recommender is a switchable client. Not ranked against local-first or a hosted PKB for YouTube.
