LSQ: The Linked SPARQL Queries Dataset

LSQ: The Linked SPARQL Queries Dataset

Building the command line client

Build the whole project with

mvn clean install

Build the command line client with

cd lsq-cli
mvn assembly:assembly

A self-contained jar is then located under lsq-cli/target/lsq-cli-{version}-jar-with-dependencies.jar You can run it with

java -cp `find . -name 'lsq*jar-with-dependencies.jar'` org.aksw.simba.lsq.cli.main.MainLSQ

alias lsq=java -cp `find {your-absolute-folder} -name 'lsq*jar-with-dependencies.jar'` org.aksw.simba.lsq.cli.main.MainLSQ

Building the debian package

This happends when you build the project (under lsq-debian-cli/target) You can conveniently install it with

sudo dpkg -i `find . -name '*.deb'`

####LSQ Homepage The Linked Dataset, a SPARQL endpoint, and complete dumps are all available on the LSQ homepage along with pointers a VoID description, example LSQ queries, and various other dataset assets.
