Example
{
"CONFIG": "DBPEDIA_CONFIG",

"type": "LIST_ALL",
"linkTo": "person"
},
"SUBJECTS": [
{
"uri": "http://dbpedia.org/ontology/Person",
"view": true,
"alias": "person",
"properties": []
}

npm install -g vsbl2sparql
cat example.json | vsbl2sparql # Read from stdin, write to stdout
cat example.json | vsbl2sparql -o example.sparql # Read from stdin, write to example.sparql
vsbl2sparql example.json # Read from file, write to stdout
vsbl2sparql example.json -o example.sparql # Read from file, write to example.sparql
#Alternative reading from file:
vsbl2sparql < example.json > example.sparqlnpm usage
