Crate rdf_types

The Resource Description Framework (RDF) is a very simple graph data model defined by the World Wide Web Consortium (W3C) to represent arbitrary pieces of information, primarily intended for the web. Nodes of the graph are called resources, and resources are connected together using relations, which are resources themselves.

This is a utility library providing common types, data-structures, traits, constants and macro definitions to deal with RDF data:

• IRIs (through the iref crate), blank node identifiers and literals to represent resources in their lexical form as terms;
• Triples and quads;
• Interpretations projecting resources from the lexical domain to the value domain;
• Graphs and datasets representing collections of interpreted triples/quads.
