PDTF schema and supporting material

This is the implementation-facing PDTF schema material: the JSON Schemas and overlays, data dictionary, business glossary, implementation guidance and attributed evidence of use. It documents a schema-led exchange contract, not an OPDA-endorsed scheme.

One family, different evidence states

The v3.5.0 JSON Schema package is the published technical implementation. Supporting terminology, guidance, pilots and evidence keep the status shown on their own pages; this category neither promotes every record to the same authority nor claims endorsement of a scheme.

How this relates to the schema-derived ontology

The ontology derived from the PDTF schema was derived from this schema-led corpus. The JSON tree remains useful for implementation compatibility and traceability, but its nesting does not by itself establish the identities and relationships used in future SPDTF modelling.
