Streams Examples

Parse triples from file card.ttl and forward them to the graph.

var parser = new TurtleParser(fs.createReadStream('card.ttl'))
var graph = new Graph()

var stream = parser.match()

stream.once('end', function () {
  console.log('done')
})

graph.import(stream)

Parse triples from file card.ttl and forward only the triples matching the s p pattern to the graph.

var parser = new TurtleParser(fs.createReadStream('card.ttl'))
var graph = new Graph()

var stream = parser.match(
  rdf.iri('http://example.org/subject'),
  rdf.iri('http://example.org/predicate'))

stream.once('end', function () {
  console.log('done')
})

graph.import(stream)

Write triples to card.ttl file

var serializer = new TurtleSerializer(fs.createWriteStream('card.ttl'))
var graph = new Graph(/* quads .... */)

serializer.import(graph.match())
