In case you watched the "DriftR" screencast I created in December, there is now a live version online. (I dropped the initial name, my blog posts suddenly showed up in CrunchBase. ;-)

Grawiki is a SPARQL-based Data Wiki, a little bit inspired by freebase, less impressive, feature-rich, scalable and all that, but, well, OpenSource, SemWeb-enabled, and decentralized (each Grawiki installation can import selected graphs from other ones, back-POSTing is in the works). As it seems that I forgot to write-protect the instance mentioned above, you can play with it if you like. You'll most probably encounter bugs, the built-in inferencer is still at alpha stage, and editing of consolidated bnodes is quite tricky to implement. I'll tweak things in a day or two.

With Grawiki, I think I finally have (the start of) a tool that could work nicely for ad-hoc RDF editing and aggregation (it can import RDF and certain microformats). Oh, and a personal URI, and a FOAF file. At last ;-)

I'm now considering the addition of RDFa injections as a possible next step, the current editor uses a home-grown mechanism to activate the editing hooks and stuff, which was easier to implement and debug in my XHTML 1.0 development environment. Stay tuned, a download site probably won't be up before next week, gotta focus on urrrgent SWEO/knowee todos first...
