Setup your own SPARQL Endpoint

KBox

For testing you can setup a local SPARQL endpoint with a single command using KBox, which you can install using pip install kbox or using docker, which we show here:

docker run -p 8080:8080 aksw/kbox:v0.0.2-alpha -server -kb "http://www.snik.eu/ontology" -install

Ignore the message and open http://localhost:8080/ in a browser.

Existing Virtuoso SPARQL Endpoint

All in one Graph

Run scripts/combine to merge everything into one file /tmp/snik.ttl, which you can upload to the graph http://www.snik.eu/ontology.

Graph Group and Subgraphs

1. Go to “Linked Data”->"Quad Store Upload” and upload the files.

File	Graph
meta.ttl	http://www.snik.eu/ontology/meta
bb.ttl	http://www.snik.eu/ontology/bb
ob.ttl	http://www.snik.eu/ontology/ob
ciox.ttl	http://www.snik.eu/ontology/ciox
it4it.ttl	http://www.snik.eu/ontology/it4it
limes.nt	http://www.snik.eu/ontology/limes-exact
match.nt	http://www.snik.eu/ontology/match

Check if it worked by querying SELECT COUNT(*) ?graph {GRAPH ?graph {?s ?p ?o.}} ORDER BY DESC(COUNT(*)).

2. Add graphs to the graph group in the Virtuoso Conductor ISQL panel and create the namespaces

    DB.DBA.RDF_GRAPH_GROUP_CREATE('http://www.snik.eu/ontology',1);
    DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.snik.eu/ontology', 'http://www.snik.eu/ontology/bb');
    DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.snik.eu/ontology', 'http://www.snik.eu/ontology/ob');
    DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.snik.eu/ontology', 'http://www.snik.eu/ontology/meta');
    DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.snik.eu/ontology', 'http://www.snik.eu/ontology/ciox');
    DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.snik.eu/ontology', 'http://www.snik.eu/ontology/it4it');
    DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.snik.eu/ontology', 'http://www.snik.eu/ontology/he');
    DB.DBA.XML_SET_NS_DECL ('sniko', 'http://www.snik.eu/ontology/', 2);                
    DB.DBA.XML_SET_NS_DECL ('meta', 'http://www.snik.eu/ontology/meta/', 2);
    DB.DBA.XML_SET_NS_DECL ('bb', 'http://www.snik.eu/ontology/bb/', 2);
    DB.DBA.XML_SET_NS_DECL ('ob', 'http://www.snik.eu/ontology/ob/', 2);
    DB.DBA.XML_SET_NS_DECL ('he', 'http://www.snik.eu/ontology/he/', 2);
    DB.DBA.XML_SET_NS_DECL ('ciox', 'http://www.snik.eu/ontology/ciox/', 2);
    DB.DBA.XML_SET_NS_DECL ('it4it', 'http://www.snik.eu/ontology/it4it/', 2);
   

3. (Optional) Add virtual Triples

   1. Query scripts/sparql/construct_virtual_triples_and_missing.sparql.txt as N-Triples
   2. Upload the result to the graph http://www.snik.eu/ontology/virtual

Editing for Project Members

• Edit only with a text editor.

• Please make sure that you produce the smallest diff possible for your changes, e.g. don't use a tool that shuffles the definition locations around or changes line endings or indentation.

• Verify after editing with:

  rapper -i turtle -c filename.ttl

SHACL

SHACL shapes for closed-world validation are included in shacl.ttl. Validate with scripts/shacl.

Docker

The docker compose setup includes a Virtuoso SPARQL endpoint preloaded with the different SNIK graphs and namespaces, an RDF Browser and more.

License

Because we extracted the triples from copyrighted books with permission of the publishers, we chose a noncommercial license with copyleft, the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International, see LICENCE for details. The tools developed in the SNIK project have the same license for simplicity's sake and there was never a reason to change it. However we want to encourage reuse, modification, derivation and distribution as much as possible, so if that license is a problem for you please contact Prof. Winter and we try our best to find a solution.
