.nt file parser

NT Parser

This parser processes any .nt file according to the grammar specified in https://www.w3.org/TR/n-triples/#n-triples-grammar

Build

mkdir -p build
cd build
cmake ..
make

• This will generate the static library libntparser.a
• Also a sample split_nt program that separates IRIS, Blank Nodes and Literals in 3 different files, separated by new lines

Library usage

#include <fstream>
#include <iostream>
#include <nt_parser.hpp>

void processor(NTTriple *ntriple, void *) {
  // ntriple->subject, ntriple->predicate, ntriple->object
  // each one has a "char *data" containing the full string of the resource
  // also each resource has a type that can be one of IRI, LITERAL or BLANK_NODE
  // eg
  std::cout << "Resource " << ntriple->subject.data << " has type "
            << ntriple->subject.type << std::endl;
}

int main(int argc, char **argv) {
  std::ifstream ifs(argv[1]);
  NTParser parser(&ifs, processor);
  parser.parse();
}
