NAME

       tracker3-endpoint - Create a SPARQL endpoint

SYNOPSIS

       tracker3 endpoint [--dbus-service | -b] <service_name>
                         [--database-path | -d] <database_path>
                         [[--ontology | -o] <ontology_name> |
                          [--ontology-path | -p] <ontology_path>]
                         [--http-port] <port>
                         [--loopback]
                         [[--system | --session]]

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

       The database itself will be stored according to database_path.

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

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

       --loopback
           Allows only HTTP connections in the loopback device. Only effective with HTTP
           endpoints.

EXAMPLES

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

           $ tracker3 endpoint -b org.example.Example1 -o nepomuk -d /tmp/example1

       Access this endpoint with the tracker3-sparql(1) subcommand.

           $ tracker3 sparql --dbus-service org.example.Example1 -q "
             SELECT ?s ?o
             WHERE {
               ?u a ?o
             }"

       Export a Nepomuk endpoint via HTTP.

           $ tracker3 endpoint --http-port 8080 -o nepomuk --loopback

       Access this endpoint via HTTP.

           $ tracker3 sparql --remote-service http://127.0.0.1:8080/sparql -q "
             SELECT ?u {
               ?u a rdfs:Resource
             }"
