For all of you out there writing droves of RDF, churning out endless amounts of Notation 3, and doing it all in Vim.. (we must be in the millions I'm sure), be sure to check out my little RDF Namespace-complete — giving you RDF Vocabulary/Model Omni-Completion for Vim 7+. Requires Vim compiled with Python and RDFLib.
On a related note, I've been using RDFLib a lot lately (around the clock as it seems). It's an honor to contribute in an ever so small way to it, and it's great to see it progressing so well (it's been mature for years if that needs to be said). The SPARQL-support is working, and along with Chimezie Ogbuji's FuXi there is now an even stronger Python RDF platform to work with.
