The language of the future! Semantic web and all (if you like ontologies).

There's actually a long dormant textmate tmbundle for n3 around, which I installed on textastic. It "works", and is not bad, but it fails to deliver comprehensive highlighting and it's very far from a pro mode à la emacs.

I've now been using textastic for all of, what, three or four days. It is so cool it defies the laws of coolness. I'm geeting a bluetooth keyboard just so I can work more with it.
