TINYSPARQL-QUERY(1) TinySPARQL manual TINYSPARQL-QUERY(1) NAME tinysparql-query - Query to SPARQL endpoints. SYNOPSIS tinysparql query [(-d |--database) <file> | (-b | --dbus-service) <busname> | (-r | --remote-service) <url>] (-f | --file) <file>] [(-u | --update)] [-a <parameter>:<value>]... [SPARQL] DESCRIPTION This command allows running queries or updates on a SPARQL endpoint. When the caller runs a query, the query is in the SPARQL language. This can be done two ways. Either by providing a file with the query or by providing a string with the sparql query. The file argument can be either a local path or a URI. It also does not have to be an absolute path. OPTIONS -b, --dbus-service=<service_name> Connects to a SPARQL endpoint at a D-Bus name. -d, --database-path=<database_path> Connects to a database by location in the filesystem. -r, --remote-service=<url> Connects to a HTTP SPARQL endpoint. -f, --file=<file> Use a file with SPARQL content to query or update. -u, --update This has to be used with --query. This tells "tinysparql query" to use the SPARQL update extensions so it knows it isn't a regular data lookup request. So if your query is intended to change data in the database, this option is needed. -a, --arg=<parameter>:<value> Provides an argument for a parameter declared in the SPARQL query string. This may be used with --file, --query or --update. Multiple arguments may be provided for multiple parameters. Argument values are provided as a colon separated string containing 3 values: name, type and value. The name is the same as used in the query string, the value is the desired value, and the type is a single-character string defining the type: • i: The value will describe an integer • d: The value will describe a floating point number • b: The value will describe a boolean • s: The value will describe a plain string EXAMPLES Querying a D-Bus endpoint $ tinysparql query --dbus-service org.example.Endpoint "SELECT ('Hello World' AS ?str) {}" Updating a database directly from a query in a file $ tinysparql query --database /tmp/db/ --update --file ./update.rq Using --arg to provide a arguments to query parameters $ tinysparql query -b org.example.Endpoint \ -a name:s:"John" -a age:i:42 -a available:b:true \ "SELECT (~name AS ?name) (~age AS ?age) (~available AS ?avail) { }" SEE ALSO tinysparql-endpoint(1). https://gnome.pages.gitlab.gnome.org/tinysparql/tutorial.html. 3.8.2 04/12/2025 TINYSPARQL-QUERY(1)
