It seems that RDF has finally got its groove back. "RDF can be readable?" is more interesting in what's been posted in the comments and the links rather than the actual posting (hmm metadata). It seems that Pie/Echo/Atom is unifying RSS 1.0 and RSS 2.0.
Jon Udell has a piece on RDF and symbol grounding he really likes Shelley's book and querying RDF: "This is cool. RDF triples are relations, and here we see that they're amenable to relational processing. I can grok that." I'm not sure that anyone is willing to say that RDF solves the "symbol grounding problem".
Lots of interesting stuff posted about graphs and trees from a recent conference. Including RDF Twig (based on Jena) which extends XSLT for RDF.
