graphy is a collection of high-performane RDF libraries for JavaScript developers with a focus on usability.

Each package works with both Node.js and the browser (with the help of a bundler such as Browserify or Webpack).

Features

• Read RDF documents using streams. Includes support for N-Triples (.nt), N-Quads (.nq), Turtle (.ttl), and TriG (.trig).
• Write RDF data using streaming transforms with the awesome and intuitive concise triples and concise quads language.
• Construct RDF data using ES object literals that reflect the tree-like structure of quads, graph -> subject -> predicate -> object, including nested blank nodes and RDF collections.
• Compute the union, intersection, difference or subtraction between multiple RDF graphs analagous to Set Algebra.
• Compare two RDF graphs for isomoprhic equivalence, containment, and disjointness by first canonicalizing them with the RDF Dataset Normalization Algorithm.
• Transform RDF data from the command-line by piping them through a series of sub-commands.
• Scan RDF documents and run custom code using multiple threads for maximum throughput.
