Crate rdftk_core[−][src]
Expand description
This crate provides an implementation of the RDF abstract syntax along with a Resource
type
that provides a builder-like experience for models.
From RDF 1.1 Concepts and Abstract Syntax;
The core structure of the abstract syntax is a set of triples, each consisting of a subject, a predicate and an object. A set of such triples is called an RDF graph. An RDF graph can be visualized as a node and directed-arc diagram, in which each triple is represented as a node-arc-node link.
There can be three kinds of nodes in an RDF graph: IRIs, literals, and blank nodes.
In this library the triple, or statement, as well as subject, predicate, and object types are
in the module statement
. Literal’s as objects are supported in the
literal
module. Traits that describe graphs are provided by the
graph
module.
Additional features are provided such as support for data sets (module data_set
)
as well as support for extensions to the core RDF abstract model such as
RDF-star.
Example
use rdftk_core::{Statement, SubjectNode, ObjectNode}; use rdftk_core::statement::StatementList; use rdftk_iri::IRI; use std::rc::Rc; use std::str::FromStr; let mut statements: StatementList = Default::default(); statements.push(Statement::new( SubjectNode::from(IRI::from_str("http://en.wikipedia.org/wiki/Tony_Benn").unwrap()).into(), IRI::from_str("http://purl.org/dc/elements/1.1/title").unwrap().into(), ObjectNode::literal_str("Tony Benn").into(), ).into());

Modules
data_set | Provides an implementation of the W3C RDF 1.1: On Semantics of RDF Datasets recommendation. Additional semantics taken from RDF 1.1 TriG, RDF Dataset Language. |
error | The shared |
graph | Traits which describe the core capabilities of a graph. Note that this crate does not provide an implementation of these traits as they are very dependent on their usage for performance, and any backing storage. |
literal | The |
qname | Qualified names, names with the form |
resource | Implementation of the |
statement | This module provides types for the RDF Statement (triple) concept. |
