NAME

6       tracker3-endpoint - Create a SPARQL endpoint

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       The database itself will be stored according to database_path.
32

OPTIONS

34       -b, --dbus-service=<service_name>
35           Service name to use on the endpoint.
36
37       -d, --database-path=<database_path>
38           The path where the database will be stored.
39
40       -o, --ontology
41           The name of an ontology in $datadir/tracker/ontologies to use on
42           the constructed database.
43
44       -p, --ontology-path
45           Full path to an ontology to use on the constructed database.
46
47       --session
48           Use the session bus. This is the default.
49
50       --system
51           Use the system bus.
52
53       -l, --list
54           List all SPARQL endpoints available in DBus
55
56       --http-port
57           Creates a HTTP endpoint that listens in the specified port
58
59       --loopback
60           Allows only HTTP connections in the loopback device. Only effective
61           with HTTP endpoints.
62

EXAMPLES

64       Export a Nepomuk endpoint with the org.example.Example1 bus name.
65
66           $ tracker3 endpoint -b org.example.Example1 -o nepomuk -d /tmp/example1
67
68       Access this endpoint with the tracker3-sparql(1) subcommand.
69
70           $ tracker3 sparql --dbus-service org.example.Example1 -q "
71             SELECT ?s ?o
72             WHERE {
73               ?u a ?o
74             }"
75
76       Export a Nepomuk endpoint via HTTP.
77
78           $ tracker3 endpoint --http-port 8080 -o nepomuk --loopback
79
80       Access this endpoint via HTTP.
81
82           $ tracker3 sparql --remote-service http://127.0.0.1:8080/sparql -q "
83             SELECT ?u {
84               ?u a rdfs:Resource
85             }"
