N-Triples, N-Quads, Turtle, and TriG readers/writers for RDF.rb.
This is a Ruby implementation of N-Triples, N-Quads, Turtle, and TriG parsers and serializers for RDF.rb implemented in Rust.
RDF::Rust::Turtle parses N-Triples, N-Quads, Turtle, and TriG into statements or triples. It also serializes to N-Triples, N-Quads, Turtle, or TriG.
Install with gem install rdf-rust-turtle
- 100% free and unencumbered public domain software.
- Implements a complete parser for Turtle.
- Compatible with Ruby >= 2.0.
- Optional streaming writer, to serialize large graphs
Instantiate a reader from a local file:
require 'rdf/rust/turtle'
graph = RDF::Graph.load("etc/doap.ttl", format: :ttl)
Define @base
and @prefix
definitions, and use for serialization using :base_uri
an :prefixes
options.
Canonicalize and validate using :canonicalize
and :validate
options.
Write a graph to a file:
RDF::Rust::Turtle::Writer.open("etc/test.ttl") do |writer|
writer << graph
end

This repository uses Git Flow to mange development and release activity. All submissions must be on a feature branch based on the develop branch to ease staging and integration.
- Do your best to adhere to the existing coding conventions and idioms.
- Don't use hard tabs, and don't leave trailing whitespace on any line.
- Do document every method you add using YARD annotations. Read the tutorial or just look at the existing code for examples.
- Don't touch the
.gemspec
,VERSION
orAUTHORS
files. If you need to change them, do so on your private branch only. - Do feel free to add yourself to the
CREDITS
file and the corresponding list in the theREADME
. Alphabetical order applies. - Do note that in order for us to merge any non-trivial changes (as a rule of thumb, additions larger than about 15 lines of code), we need an explicit public domain dedication on record from you.
