NAME App::wdq - command line access to Wikidata Query Service DESCRIPTION The command line script wdq, included in CPAN module App::wdq, provides a tool to access Wikidata Query Service . It supports formulation and execution of SPARQL SELECT queries to extract selected information from Wikidata or other Wikibase instances. INSTALLATION Either install from CPAN with all dependencies: cpanm App::wdq or install dependencies as prebuild packages (for instance Debian) and copy the wdq script to some place in your $PATH: sudo apt-get install libhttp-tiny-perl librdf-query-perl wget https://github.com/nichtich/wdq/raw/master/bin/wdq chmod +x wdq The latter method will not install this documentation.
