+   ```bash
+   java -cp cwaf-ontology/target/cwaf-ontology-1.0-SNAPSHOT.jar be.uclouvain.service.Querier full_schema.ttl sparql_query_example.txt

+   ```bash
+   java -cp cwaf-ontology/target/cwaf-ontology-1.0-SNAPSHOT.jar be.uclouvain.service.Querier full_schema.ttl -q "SELECT ?x WHERE {?x  <http://visualdataweb.org/ontCWAF/includedIn>  <http://visualdataweb.org/ontCWAF/a/file/path>}"
