This document contains some useful commands for creating a database of the DOKK
|
|
2
|
|
- |
data, that can be queried with SPARQL.

Create a database:
|
|
9
|
|
- |
|
|
10
|
|
- |
tdb2.tdbloader --loc=database dokk/data/*.ttl
|
|
11
|
|
- |
|
|
12
|
|
- |
Query from command line:
|
|
13
|
|
- |
|
|
14
|
|
- |
tdb2.tdbquery --loc=database "select distinct ?s where { ?s ?p ?o } order by ?s limit 10"
|

It's also possible to start a standalone server (Fuseki) that is queryable via
|
|
17
|
|
- |
HTTP. All you have to do is create the database first (with the above commands),
|
|
18
|
|
- |
and then start Fuseki. See "fuseki.service" for an example.
