Index & glossary
Every named resource in the schema-derived ontology — 688 entries (classes, object
and datatype properties, SKOS concepts and schemes) in one A–Z, from the SPARQL-derived
ontology model. Each entry links to its canonical page
at /pdtf/{id}. SHACL shapes have their own typed index at
SHACL shapes.
The Lease Term class and leaseTerm property are the case-independent exception and use distinct lowercase, type-scoped representation paths.
