Hi Edwin,
this is how I install Apache Jena (which includes ARQ):
wget
http://www.apache.org/dist/incubator/jena/apache-jena-2.7.0-incubating/apache-jena-2.7.0-incubating.zip
unzip apache-jena-2.7.0-incubating.zip
cd apache-jena-2.7.0-incubating
cat README ;-)
export JENAROOT=/tmp/apache-jena-2.7.0-incubating
export PATH=$JENAROOT/bin:$PATH
Load (in-memory, for small datasets only) some data and run a query:
arq --data=filename.nt "SELECT * { ..."
arq --data=filename.nt --query filename.rq
See also:
arq --help
Documentation here:
http://incubator.apache.org/jena/documentation/query/
On a Windows system there are small changes ';' instead of ':' for environment
variables and a different way to the them.
