Yes, tabulator is now built into solid which allows the browser to become a
tabulator style data browser (editor) via a shim.

The shim is called mashlib :

Mashlib is based on solid app set and solid ui :

Thanks for this feedback, very valuable.  Ive passed it on.

Well done for signing up! :)

Ah yes, good catches.  These apps were designed for the previous version of
solid, we will have to fix this over time, or remove the links.

However if you click on one of the folders, say the folder named "public"

You will get a view of tabulator / mashlib (which we need to document a bit
more)

We dont fully support n3, but pretty much everyone working on solid wants
to.  e.g. Tim, Eric, Ruben, myself are all n3 fans

Ruben did manage to get a patch to allow n3 patches, in our last version

The main thing here is that tabulator was a browser extension, this can
also be a shim.  It could even run natively in the browser.

Another thing is that each class has it's own UI.  But the user can choose
which UI they prefer, meaning an app market for rendering.

It's starting to work!  Have a look at your public folder, try creating a
new chat pane.

Post the link here, or join us on gitter :

https://gitter.im/solid/chat

And we can play around with realtime chat in the browser, or notepads,
meetings, playlists and more.

This stuff is working, if a bit buggy and undocumented.  We hope to change
that over time, but are a small team going step by step. :)
