Hi Lee,

I've put together a simple dataset that contains NASA spaceflight
data, which you could
use. The SPARQL endpoint is here:


The tutorial slides and SPARQL queries are all online, the material is here:


And linked from there is SPARQL editor that is configured to use the
nasa data. The examples are
linked from the right-hand nav (click the headings to expand):


As this is a basic SPARQL tutorial, these are all simple queries, but
its a real-world dataset. I'm
adding some data about Apollo missions shortly.
