v0.1.0 — Type system for the Mensch ↔ Maschine interface

v0.1.0 — Type system for the Mensch ↔ Maschine interface

Everywhere AI touches data, a contract is missing. GERMANIC is that contract.

cargo install germanic

What is GERMANIC?

A schema-validated binary compiler for AI agents. JSON in, validated .grm binary out. If the data is incomplete, it won't compile.

Built in Rust. Zero-copy FlatBuffers. No runtime dependencies.

Highlights

Schema-Validated Compilation

• JSON → schema validation → FlatBuffer → .grm binary
• Required fields, type checking, nested validation, empty string detection
• All errors collected at once — not just the first

No Rust Knowledge Required

• germanic init --from example.json infers a schema from any JSON
• germanic compile --schema my.schema.json --input data.json compiles it
• Edit the .schema.json to mark required fields — that's it

JSON Schema Draft 7 Compatible

• Accepts both GERMANIC .schema.json and standard JSON Schema Draft 7
• Auto-detection — no flags needed

MCP Server

• 6 tools: compile, validate, inspect, schemas, init, convert
• Built on rmcp 0.8, stdio transport
• Behind mcp feature flag: cargo install germanic --features mcp

42 Domain Schemas

• Healthcare, dining, trades, education, real estate, legal, public services, mobility, business, associations, agriculture
• German + English translations
• All with fictional example data

Contract Proof

• 10 test scenarios proving what GERMANIC catches vs HTML/JSON-LD/JSON Schema
• Run it yourself: cargo test --test vertragsbeweis -- --nocapture

Install
