Has anyone managed to pass a URL with a SPARQL query to wget or curl and 
successfully retrieved data from dbpedia? When I take the wget example 
at http://groups.yahoo.com/group/govtrack/message/570 and paste the 
query at dbpedia's SNORQL interface it works[1], and when I paste the 
wget command on that page without any carriage returns onto a (Windows) 
command line [2] it doesn't get any errors, which certainly felt like a 
minor victory, but the result set was empty.

Any suggestions?

thanks,

Bob
