The top-level module of RDF.ex.
|
|
|
|
RDF.ex consists of:
|
|
|
|
- modules for the nodes of an RDF graph
|
|
- `RDF.Term`
|
|
- `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).
