The parameter options are shown in #databus-client-parameters

Requirements

  • Java: JDK 11

Execution example

Select Data

First we need to specify, the data we want to download.

Note: It is best practice to write a query to a file and pass this file as source, instead of passing the query directly as a string.

echo "PREFIX dcat:   <http://www.w3.org/ns/dcat#>
PREFIX databus: <https://dataid.dbpedia.org/databus#>

SELECT ?file WHERE
{
        GRAPH ?g
        {
                ?dataset databus:artifact <https://dev.databus.dbpedia.org/tester/testgroup/testartifact> .
                { ?distribution <http://purl.org/dc/terms/hasVersion> '2023-06-23' . }
                ?dataset dcat:distribution ?distribution .
                ?distribution databus:file ?file .
        }
}" > query.sparql

Download and Convert Data

Then we can download the selected data, and convert it to ntriple files.

java -jar databus-client.jar \
-s "query.sparql" \
-e "https://dev.databus.dbpedia.org/sparql" \
-f nt
