SPARQL command-line client based on rdflib and SPARQLWrapper.

python3 -m pip install --user git+https://github.com/FrankGrimm/sparqlcli/

Make sure pip is installed and $HOME/.local/bin/ is in your PATH.

sparqlcli endpoint

Where endpoint is either a remote SPARQL endpoint URI or a local filename.

• [-f,--format] one of html,hturtle,mdata,microdata,n3,nquads,nt,rdfa,rdfa1.0,rdfa1.1,trix,turtle,xml May be used to avoid format auto-detection when endpoint is a local file.
• [-r,--remote] Force treating endpoint as a remote SPARQL server.
• [-i,--interactive INTERACTIVE] Boolean, normally auto-detected if a tty is present.
• [-o,--output] output format, one of table,json,csv, defaults to table display.
• non-standard prefixes can be registered via --prefix=longform as well, e.g. --foaf=http://xmlns.com/foaf/0.1/

Load local file testdata/demo.nt with n-triple format and pre-register the foaf namespace:

sparqlcli "testdata/demo.nt" "--format=nt" "--foaf=http://xmlns.com/foaf/0.1/"

Same as the above with a single query and output type CSV (useful for scripting):

echo "SELECT DISTINCT ?pers WHERE { ?pers rdf:type foaf:Person }" | sparqlcli "testdata/demo.nt" --format=nt "--foaf=http://xmlns.com/foaf/0.1/" --output=csv

Query a remote dbpedia endpoint:

sparqlcli "http://dbpedia.org/sparql"

Query a remote dbpedia endpoint and output data as json:

echo "SELECT DISTINCT ?a ?b WHERE { ?a rdf:type ?b } LIMIT 5" | sparqlcli "http://dbpedia.org/sparql" --output=json

The REPL features basic auto-complete on standard SPARQL keywords and previous results.

Queries and commands are sent whenever a newline (press Return twice) is encountered or the current input ends with a ;.

In interactive mode, the following commands are available in addition to simple queries:

• .edit open current query buffer in $EDITOR (defaults to vim)
• .file <filename> load and execute query from <filename>
• .watch <filename> poll <filename> for changes and continously execute queries
• .prefixes
• up/down arrow keys: navigate through the query history
