tinysparql-endpoint - Create a SPARQL endpoint

Description

       This command allows creating SPARQL endpoints. The endpoint will be able to handle SPARQL select and
       update queries, and notify about changes in it.

       The endpoint is exported via DBus, accessible through the given service_name, either using it in a
       SERVICE clause, or by creating a dedicated bus-based SPARQL connection.

       When creating a database, the ontology_name (or alternatively, a ontology_path) must be provided in order
       to generate the database. If ontology_name is used, the ontology must exist in
       $datadir/tracker/ontologies

       Users should be careful about the --http-port option, consider using it only combined with the --loopback
       option.

       The database itself will be stored according to database_path.

Examples

       Export a Nepomuk endpoint with the org.example.Example1 bus name.

           $ tinysparql endpoint -b org.example.Example1 -o nepomuk -d /tmp/example1

       Access this endpoint with the tinysparql-sparql(1) subcommand.

           $ tinysparql sparql --dbus-service org.example.Example1 -q "
             SELECT ?s ?o
             WHERE {
               ?u a ?o
             }"

       Export a Nepomuk endpoint via HTTP.

           $ tinysparql endpoint --http-port 8080 -o nepomuk --loopback

       Access this endpoint via HTTP.

           $ tinysparql sparql --remote-service http://127.0.0.1:8080/sparql -q "
             SELECT ?u {
               ?u a rdfs:Resource
             }"

Name

       tinysparql-endpoint - Create a SPARQL endpoint

Options

-b,--dbus-service=<service_name>
           Service name to use on the endpoint.

       -d,--database-path=<database_path>
           The path where the database will be stored.

       -o,--ontology
           The name of an ontology in $datadir/tracker/ontologies to use on the constructed database.

       -p,--ontology-path
           Full path to an ontology to use on the constructed database.

       --session
           Use the session bus. This is the default.

       --system
           Use the system bus.

       -l,--list
           List all SPARQL endpoints available in DBus

       -L,--list-http
           List network-local HTTP SPARQL endpoints

       --http-port
           Creates a HTTP endpoint that listens in the specified port
