Package Exports

vsbl2sparql

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (vsbl2sparql) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.sparql

npm usage

npm install vsbl2sparql

var 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()
);
