* https://github.com/megoth/solid-app-browser-extension (Arne's "App Launcher" - work in progress)
 * also related: https://github.com/megoth/ldo-solid-app-manifest (also work in progress)
 * Started some work on vocabulary at https://github.com/megoth/ldo-solid-app-manifest/blob/main/ontology.ttl (don't have anything on authorization though - and it's very web-oriented)

Silvan, Benoit and Daniel plan to work on it.
Henry has already implemented the Linked Data event streams.

Solid Wallet was re-naming for proposa/funding purposes, essentially nothing different but the very idea of the LauncherApp.

Arne woked on
Cross browser extension 


What runs on user device(s) and what on the server somewhere in the cloud?

There is also a server side, not only the client in the browser. It is considered the first app you get, just as your WebID and pod. It launches all the other apps and manages them. It manages the apps and stores the credentials.

European Identiy Framework, blockchain based.

Can be client-server or server-server communication.

One potential use of HttpSig in the context of Notifications Protocol:
