SKOS.ex

An implementation of the W3C Simple Knowledge Organization System (SKOS) vocabulary for Elixir as Grax schemas.

The API documentation can be found here. For more information about the RDF on Elixir projects, go to https://rdf-elixir.dev.

Features

The SKOS module acts as the RDF.Vocabulary.Namespace for the SKOS vocabulary
Grax structures for all SKOS classes and their properties, for easy creation and manipulation of SKOS concepts, concept schemes, and collections
Seamless integration with all RDF on Elixir projects

Installation

Add skos to your list of dependencies in mix.exs:

def deps do
  [
    {:skos, "~> 0.1"}
  ]
end

Usage

SKOS.Concept.build!(EX.elixir(),
  pref_label: "Elixir",
  alt_label: ["Elixir language", "Elixir lang"],
  definition: "Elixir is a dynamic, functional language for building scalable and maintainable applications.",
  broader: [EX.programming_language()],
  related: [EX.erlang(), EX.beam()]
)  
|> Grax.to_rdf!(prefixes: [skos: SKOS, ex: EX])  
|> RDF.Turtle.write_string!()

produces:

@prefix ex: <http://example.com/concepts/> .
@prefix skos: <http://www.w3.org/2004/02/skos/core#> .

ex:elixir
    a skos:Concept ;
