Reuse, don't reinvent: one model for Swiss legislation across schema.org, ELI and Akoma Ntoso.

The three vocabularies align by design. schema:Legislation is owl:equivalentClass of eli:LegalResource (schema.org's Legislation was contributed to align with ELI); the Akoma Ntoso <act> is that resource's document embodiment. The FRBR levels (Work / Expression / Manifestation) give the shared spine.

Classes (by FRBR level)

FRBR level	schema.org	ELI	Akoma Ntoso
Work — the law as an idea	`Legislation`	`eli:LegalResource`	`FRBRWork`
Expression — a version / language	`Legislation (+ inLanguage, temporalCoverage)`	`eli:LegalExpression`	`FRBRExpression`
Manifestation — a format (XML/PDF/HTML)	`LegislationObject`	`eli:Format`	`FRBRManifestation / <act>`

Machine-readable

/ap/lex.context.jsonld — a JSON-LD @context binding schema:, eli:, akn: and the mapped terms.
/ap/lex.alignment.jsonld — the equivalences as owl:equivalentClass / skos:exactMatch.

Pragmatic first — a formal SKOS/OWL + SHACL version, and the Swiss publication-process vocabulary, follow.
