NAME

6       tracker3-endpoint - Create a SPARQL endpoint
7

SYNOPSIS

9       tracker3 endpoint [--dbus-service | -b] <service_name>
10                         [--database-path | -d] <database_path>
11                         [[--ontology | -o] <ontology_name> |
12                          [--ontology-path | -p] <ontology_path>]
13                         [--http-port] <port>
14                         [--loopback]
15                         [[--system | --session]]

DESCRIPTION

18       This command allows creating SPARQL endpoints. The endpoint will be
19       able to handle SPARQL select and update queries, and notify about
20       changes in it.
21
22       The endpoint is exported via DBus, accessible through the given
23       service_name, either using it in a SERVICE clause, or by creating a
24       dedicated bus-based SPARQL connection.
25
26       When creating a database, the ontology_name (or alternatively, a
27       ontology_path) must be provided in order to generate the database. If
28       ontology_name is used, the ontology must exist in
29       $datadir/tracker/ontologies
30
31       Users should be careful about the --http-port option, consider using it
32       only combined with the --loopback option.
33
34       The database itself will be stored according to database_path.
35

OPTIONS

37       -b, --dbus-service=<service_name>
38           Service name to use on the endpoint.
39
40       -d, --database-path=<database_path>
41           The path where the database will be stored.
42
43       -o, --ontology
44           The name of an ontology in $datadir/tracker/ontologies to use on
45           the constructed database.
46
47       -p, --ontology-path
48           Full path to an ontology to use on the constructed database.
49
50       --session
51           Use the session bus. This is the default.
52
53       --system
54           Use the system bus.
55
56       -l, --list
57           List all SPARQL endpoints available in DBus
58
59       --http-port
60           Creates a HTTP endpoint that listens in the specified port
61
62       --loopback
63           Allows only HTTP connections in the loopback device. Only effective
64           with HTTP endpoints.
65

EXAMPLES

67       Export a Nepomuk endpoint with the org.example.Example1 bus name.
68
69           $ tracker3 endpoint -b org.example.Example1 -o nepomuk -d /tmp/example1
70
71       Access this endpoint with the tracker3-sparql(1) subcommand.
72
73           $ tracker3 sparql --dbus-service org.example.Example1 -q "
74             SELECT ?s ?o
75             WHERE {
76               ?u a ?o
77             }"
78
79       Export a Nepomuk endpoint via HTTP.
80
81           $ tracker3 endpoint --http-port 8080 -o nepomuk --loopback
82
83       Access this endpoint via HTTP.
84
85           $ tracker3 sparql --remote-service http://127.0.0.1:8080/sparql -q "
86             SELECT ?u {
87               ?u a rdfs:Resource
88             }"
