vsbl2sparql
This package allows to parse JSONs created by the Visual SPARQL Builder and translate them to SPARQL. It is available as angular module via bower and as node module/standalone via npm.
Example
{
"CONFIG": "DBPEDIA_CONFIG",
"START": {
"type": "LIST_ALL",
"linkTo": "person"
},
"SUBJECTS": [
{
"uri": "http://dbpedia.org/ontology/Person",
"view": true,
"alias": "person",
"properties": []
}
]
}translates to
Select Distinct ?person {?person <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://dbpedia.org/ontology/Person>}standalone usage
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
npm install vsbl2sparqlvar vsbl2sparql = require('vsbl2sparql');
var json = JSON.parse('{"CONFIG":"foo","START":{"type":"LIST_ALL","linkTo":"person"},"SUBJECTS":[{"uri":"http://dbpedia.org/ontology/Person","view":true,"alias":"person","properties":[]}]}');
console.log(
vsbl2sparql.translateJSONToSPARQL(json).toString()
);
