[redland-dev] SPARQL

[Donald Ephraim Curtis]

So, i'm trying to run some SPARQL tests with the C redland libraries.

Everytime i do a WHERE { ... } it gives me a syntax error.  Namely,

librdf error URI file:///usr/local/mp/development/rsi/src/:1 - syntax 
error, unexpected '?'
rad_systems_to_glist : Failed to gather query results.

from this query:

SELECT ?system WHERE { ?system 
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type> 
<http://milkbox.net/rsi-schema#System> }

am i doing something wrong?
