//! This crate provides the tools necessary to parse RDF graphs. It currently contains a
//! full (with very few exceptions) [`Turtle`](http://www.w3.org/TR/turtle/) parser that can parse arbitrary 
//! URIs, Triples, and Graphs (see [`TurtleParser`](crate::parsing::TurtleParser) for example usage).
//!
//! # Goals
//!
//! * To provide a simple and easy-to-use RDF parsing API.
//! * To act as an inference engine capable of filling a graph with all the triples that can be
//! inferred from the parsed data.
//!
//! # Usage
//!
//! This crate is not on [crates.io](https://crates.io) and thus the `Cargo.toml` entry looks like
//! the following:
//!
//! ```
//! [dependencies]
//! rdf-rs = { git = "https://github.com/CoBrooks/rdf-rs" }
//! ```
//!
//! [`TurtleParser`]: crate::parsing::TurtleParser


/// Contains all of the core rdf data structures, such as [`Uri`](crate::core::Uri) and
/// [`Triple`](crate::core::Triple).
