Subject: [PATCH] Merge repository data.dokk.org.git

There was a separate repository named "data.dokk.org.git" that only
contained basic instructions for creating a TDB2 (Apache Jena) database
and instructions for starting Fuseki. The repository has been deleted
and the little content in it has been moved here.

+This document contains some useful commands for creating a database of the DOKK
+data, that can be queried with SPARQL.
+
+Note: the tools used here are available for download at
+      <https://jena.apache.org/download/#apache-jena-binary-distributions>
+      Just download "apache-jena-<version>.tar.gz" and "apache-jena-fuseki-<version>.tar.gz"
+
+Create a database:
+
+    tdb2.tdbloader --loc=database dokk/data/*.ttl
+
+Query from command line:
+
+    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
+HTTP. All you have to do is create the database first (with the above commands),
+and then start Fuseki. For an example see the "fuseki.service" file.
