An implementation of theW3C PROV (Provenance) vocabulary for Elixir as Grax schemas.

The API documentation can be foundhere.For more information about the RDF on Elixir projects, go tohttps://rdf-elixir.dev.

• ThePROV module acts as theRDF.Vocabulary.Namespace for the PROV vocabulary
• Grax structures for all PROV classes and their properties, for easycreation and manipulation of provenance information including entities, activities, and agents
• Seamless integration with all RDF on Elixir projects

Addprov to your list of dependencies inmix.exs:

defdepsdo[{:prov,"~> 0.1"}]end

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#> .ex:reporta prov:Entity ;    prov:generatedAtTime"2024-08-06T23:46:18.503394Z"^^xsd:dateTime ;    prov:wasAttributedTo ex:researcher ;    prov:wasDerivedFrom ex:data ;    prov:wasGeneratedBy ex:compile .
