openbim-epd

ISO 22057 environmental product declaration (EPD) data-template contracts for Rust.

Status

Reserved scaffold. Version 0.1.0 does not parse, write, or validate EPD datasets. It currently provides:

  • an explicit ISO 22057:2022 edition contract;
  • all 18 EPD information-module codes, including the aggregated A1-A3 value;
  • exact code lookup and semantic grouping, with D explicitly beyond the product-system boundary;
  • unit tests for those contracts.

ISO 22057 defines EPD data-template information and mappings, not a universal XML namespace or XSD. This crate deliberately does not invent one. Format adapters such as ILCD+EPD or openEPD require independent, versioned implementations and conformance evidence.

See the repository capability table before relying on a feature.

Example

use openbim_epd::{InformationModule, LifeCycleStage, StandardEdition};

assert_eq!(StandardEdition::CURRENT.designation(), "ISO 22057:2022");
assert_eq!(InformationModule::B7.code(), "B7");
assert_eq!(InformationModule::C4.stage(), LifeCycleStage::EndOfLife);
assert_eq!(InformationModule::from_code("A0"), None);

Architecture

EPD consumes data-template and, eventually, IFC contracts. IFC, core, codec, and data-template substrate layers must never depend on EPD. See the architecture document.

No restricted ISO/CEN source document or annex workbook is vendored in this crate. Types may be implemented from legitimately accessed specifications, but standards possession does not establish a right to redistribute source material.
