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:

var vsbl2sparql = require('vsbl2sparql');
