Reference Implementations ◈︎
AIOSchema has reference implementations in six languages. All pass the full conformance test suite (TV-01 through TV-24) and all 18 cross-verification vectors. Source code is available at github.com/aioschema/aioschema.

All implementations are in the
aioschema/aioschema monorepo under
implementations/. The
API reference
documents the language-neutral contracts each implementation satisfies.
Cross-Verification
The cross-verification suite (cross_verify_vectors.json) contains 18
deterministic vectors. All implementations must produce
byte-identical output for every vector. This is the minimum bar for conformance.
Vectors cover: hash computation (SHA-256, SHA-384, SHA3-256), canonical JSON
serialization, core_fingerprint derivation, manifest verification (hard match,
tampered inputs, missing fields, invalid timestamps), public_key fingerprint
cross-check, ai_declaration constraint validation, and the extension size limit.
CLI
The AIOSchema CLI is available via npm:
npm install -g @aioschema/cli
aioschema generate myfile.pdf
aioschema verify myfile.pdf myfile.pdf.aios.json
Implementing AIOSchema
A developer should be able to read the specification in under an hour and produce a working implementation in a day. The standard uses only widely-available cryptographic primitives – no custom algorithms, no proprietary dependencies.
