treasury: namespace
This page is the dereference target of the treasury: namespace IRI:
The namespace ends in #; stripping the fragment lands you here. The
ontology is published as a Turtle document at
which declares every class and predicate in the treasury: namespace.
The TTL source of truth lives in the repository at
vocab/treasury/overlay.ttl.
treasury: carries the treasury-overlay vocabulary: off-chain
entity declarations, attestations, vendor accountability. It exists so
the ledger-level cardano: namespace is not
polluted by application terms. Case-study overlay.yaml files opt in
to this vocabulary via an explicit imports: [treasury] block;
predicates from non-imported ontologies fail the parser with a clear
error.
The emitted overlay Turtle declares
owl:imports <https://lambdasistemi.github.io/cardano-ledger-rdf/vocab/treasury/overlay>
so downstream consumers (SPARQL engines, SHACL, LLMs) can resolve
predicate provenance.
For ownership and the standard SPARQL PREFIX line, see the
Vocabulary index.
