PROV.ex

An implementation of the W3C PROV (Provenance) 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 PROV module acts as the RDF.Vocabulary.Namespace for the PROV vocabulary
• Grax structures for all PROV classes and their properties, for easy creation and manipulation of provenance information including entities, activities, and agents
• Seamless integration with all RDF on Elixir projects

Installation

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

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

Usage

PROV.Entity.build!(EX.report(),
  was_generated_by: EX.compile(),
  was_attributed_to: EX.researcher(),
  generated_at: DateTime.utc_now(),
  was_derived_from: EX.data()
) 
|> Grax.to_rdf!(prefixes: [prov: PROV, ex: EX, xsd: RDF.NS.XSD]) 
|> RDF.Turtle.write_string!()

produces:

@prefix ex: <http://example.com/> .
@prefix prov: <http://www.w3.org/ns/prov#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
