Usage

• From a string.

var rdfTranslator = require('rdf-translator');
var str = `
  <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
           xmlns:foaf="http://xmlns.com/foaf/0.1/">
   <foaf:Person rdf:about="http://dbpedia.org/page/Spider-Man">
     <foaf:name>Peter Parker</foaf:name>
     <foaf:mbox rdf:resource="mailto:[e-mail]"/>
   </foaf:Person>
  </rdf:RDF>
`
 
rdfTranslator(str, 'xml', 'n3')
  .then(data => {
    console.log(data);
    \\ <http://dbpedia.org/page/Spider-Man> <http://xmlns.com/foaf/0.1/name> "Peter Parker" .
    \\ <http://dbpedia.org/page/Spider-Man> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://xmlns.com/foaf/0.1/Person> .
    \\ <http://dbpedia.org/page/Spider-Man> <http://xmlns.com/foaf/0.1/mbox> <mailto:[e-mail]> .
  }).catch(err => {
    console.error(err);
  });
 

In alternative, with traditional callbacks:

rdfTranslator(str, 'xml', 'n3', function(err, data) {
    if (err) return console.error(err);
    console.log(data);
});

• From a URI

var rdfTranslator = require('rdf-translator');
 
let uri = 'https://raw.githubusercontent.com/DOREMUS-ANR/doremus-ontology/master/doremus.ttl';
rdfTranslator(uri, 'n3', 'json-ld')
  .then( data => {
    var json == JSON.parse(data);
    // your code here
  });
