RDFtk: Core

This crate provides the core RDF data model; concrete implementations for Statements and Literals, along with a Resource type that provides a builder-like experience for models.

Example

```rust use rdftkcore::{Literal, Statement, StatementList, SubjectNode}; use rdftkiri::IRI; use std::rc::Rc; use std::str::FromStr;

pub fn make_statements() -> StatementList { let mut statements: StatementList = Default::default();

statements.push(Statement::new(
    SubjectNode::named(IRI::from_str("http://en.wikipedia.org/wiki/Tony_Benn").unwrap()),
    IRI::from_str("http://purl.org/dc/elements/1.1/title").unwrap(),
    Literal::new("Tony Benn").into(),
).into());
// ...
statements

} ```
