ANN: asqc - A Simple SPARQL Query Client

A simple command-line utility for issuing/testing SPARQL queries.

constraining results in the next, or filtering RDF data through CONSTRUCT 
queries.  There are some usage examples at

I use it mainly for query testing and/or shell scripts, and scratching similar 
itches - more as a developer tool than a polished product.  The heavy lifting of 
SPARQL query processing is handled by rdflib ( 
and friends.

There are still some rough edges (error reporting isn't great), but it does seem 
to mostly achieve what it says on the box.

EU-funded Wf4Ever project (
