Provenance

vtl-prov exposes fr.insee.vtl.prov.Provenance as the public entry point.

Provenance.run evaluates the script on the caller’s ScriptEngine, extracts an IR graph, then projects it to an SDTH Program:

Program program = Provenance.run(engine, script, "program-id", "program-name");

Packages under the façade:

• fr.insee.vtl.prov.extract — parse → support-check → structure oracle → ProvGraph
• fr.insee.vtl.prov.ir — ProvGraph
• fr.insee.vtl.prov.view — SdthProgramView (production) / RichRdfView (experimental)
• fr.insee.vtl.prov.prov — SDTH beans (Program, ProgramStep, …)
• fr.insee.vtl.prov.utils — RDFUtils, …

Program

run returns a Program containing steps, dataframes, variables, and entity lineage.

RDF

vtl-prov embeds Jena and exposes RDFUtils.

Build RDF model

Model model = RDFUtils.buildModel(program);

RDF serialization

String jsonLd = RDFUtils.serialize(model, "JSON-LD");
