defmodule RDF do @moduledoc """ The top-level module of RDF.ex. RDF.ex consists of: - modules for the nodes of an RDF graph - `RDF.IRI` - `RDF.BlankNode` - `RDF.Literal` - a facility for the mapping of URIs of a vocabulary to Elixir modules and functions: `RDF.Vocabulary.Namespace` - modules for the construction of statements - `RDF.Triple` - `RDF.Quad` - `RDF.Statement` - modules for collections of statements - `RDF.Description` - `RDF.Graph` - `RDF.Dataset` - `RDF.Data` - `RDF.List` - functions for working with RDF serializations: `RDF.Serialization` - behaviours for the definition of RDF serialization formats - `RDF.Serialization.Format` - `RDF.Serialization.Decoder` - `RDF.Serialization.Encoder` - and the implementation of various RDF serialization formats - `RDF.NTriples` - `RDF.NQuads` - `RDF.Turtle` This top-level module provides shortcut functions for the construction of the basic elements and structures of RDF and some general helper functions. For a general introduction you may refer to the [README](readme.html).
