Your data is a URL. A 6KB reactive framework for building apps on linked data. Edit a value — it auto-saves via HTTP PUT. Open the same URL on another device — it live-syncs via WebSocket.
No build step. No dependencies. No virtual DOM.
Create index.html, copy the code from the Quick Start, open in browser. That's it.
LOSOS data is JSON-LD. When no explicit @context is supplied, the recommended default vocabulary is urn:solid: — a stable, vocabulary-agnostic surface that maps (via owl:sameAs) to the canonical IRIs in FOAF, Schema.org, dcterms, ActivityStreams, and other common vocabularies.
This means panes can register against urn:solid: types (e.g. urn:solid:Person) and match data regardless of which upstream vocabulary the source app used. Pods are vocab-heterogeneous; urn:solid is the indirection layer that lets a single pane handle every variant.
