Extract information from wikidata in one line of bash (with `jq`)

wikidata_extract_official_websites.sh

# Wikidata can be queried in SPARQL using https://query.wikidata.org/
# However, result size is limited. So this little script processes official wikidata dumps in order to extract information.
# This allows to make simple queries, and stream the results

curl --silent "https://dumps.wikimedia.org/wikidatawiki/entities/latest-all.json.bz2" |   bunzip2 |   jq --stream -c -M -r '
    select(
        (( .[0][1] == "labels" and .[0][2] == "en"   and .[0][3] == "value" ) and length > 1) or
         ( .[0][1] == "claims" and .[0][2] == "P856" and .[0][6] == "value" )
       ) | .[1] '
