"Getting Real" with RDF and SPARQL(About) "Getting Real" is an agile approach to web application development. This article explains how it can be successfully combined with the flexibility of semantic web technologies.
Grawiki - A Wiki (and aggregator) for graph-shaped data - benjamin nowack's blog(About) 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 ;-)
