dpp-domain

Core domain types, port traits, and schema validation for the Odal Node Digital Product Passport system.

This is the foundational crate. All other dpp-* crates depend on it. It contains everything that changes when EU regulations change — and nothing else.

When to use this crate

You need the DPP data model: Passport, SectorData, TransferChain.
You are implementing a platform adapter (database, HTTP layer) and need the port trait interfaces: PassportRepository, IdentityPort, PluginHost, etc.
You want to validate passport data against embedded JSON schemas.

Example

use dpp_domain::{Passport, PassportId, Sector, SectorData, TextileData, FibreEntry};

let passport = Passport::new(
    PassportId::new(),
    "did:web:manufacturer.example.com".into(),
    Sector::Textile,
    SectorData::Textile(TextileData {
        fibre_composition: vec![FibreEntry {
            fibre_type: "Organic Cotton".into(),
            percentage: 100.0,
            country_of_origin: Some("TR".into()),
        }],
        care_instructions: "Machine wash 30°C".into(),
        country_of_manufacture: "TR".into(),
        ..Default::default()
    }),
);

passport.validate().unwrap();
