    Implementation

    How to actually build with PDTF. The Modelling section covers what the vocabulary is; this section covers what to do with it: install the schemas package, compose the overlays your use case needs, run validation, produce and verify claims, and emit interoperable JSON-LD.

    Getting started

    From zero to a validating transaction in a few minutes.

    The bread-and-butter operations every PDTF integration needs.

    Schema composition

    How getTransactionSchema(id, overlays[]) merges base + overlays via deepmerge. Worked examples for estate agents, conveyancers, and lenders.

    Validation

    Using Ajv, getValidator, validating verified claims with validateVerifiedClaims, error decoding.

    Wrapping transaction fields as W3C Verifiable Credentials with PDTF-specific claim shapes.
