From the description:
An introduction to the W3C query language for RDF. See http://www.learningsparql.com for more.
I first saw this in Bob DuCharme’s post: SPARQL: the video.
Nothing new for old hands but useful to pass on to newcomers.
I say nothing new, I did learn that Bob has a Korg Monotron synthesizer. Looking forward to more “accompanied” blog posts. 😉
