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 <https://query.wikidata.org/>.
    It supports formulation and execution of SPARQL SELECT queries
    <http://www.w3.org/TR/sparql11-query/#select> 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.

USAGE
    Get a documented list of all command line options:

      wdq --help

EXAMPLES
      # get all parts of the solar system
      wdq -q '{ ?c wdt:P361 wd:Q544 }'

      # print expanded SPARQL query 
      wdq -n -q '{ ?c wdt:P361 wd:Q544 }'
  
      # execute query and return tab-separated values
      wdq -f tsv < query

      # execute query, abbreviate Wikidata identifier, emit simple JSON
      wdq -f simple --ids < query

      # print result as Markdown Table (requires Catmandu::Exporter::Table)
      wdq --export Table < query
