dpp-digital-link

GS1 Digital Link URL parsing, link-type content negotiation, and Asset Administration Shell (AAS) submodel mapping for the Odal Node Digital Product Passport system.

Pure Rust, no I/O, no network calls.

When to use this crate

You need to parse or build GS1 Digital Link URLs (GTIN, serial, batch).
You are resolving DPP links and need to negotiate content by link type, media type, or access tier.
You want to map a DPP serde_json::Value to an AAS submodel for Industry 4.0 interoperability.

Example

use dpp_digital_link::{DigitalLink, AccessTier, negotiate, Gs1LinkType};

// Parse a GS1 Digital Link URL
let link = DigitalLink::parse(
    "https://id.gs1.org/01/09521234543213/21/ABC123",
).unwrap();
println!("GTIN: {}", link.gtin);
println!("Serial: {}", link.serial.unwrap());

// Negotiate the best link for a professional-tier consumer
let descriptors = vec![/* LinkDescriptor items */];
let best = negotiate(&descriptors, None, None, AccessTier::Professional);
