openbim-dt

Pure-Rust ISO 23387 edition 2 data-template contracts and a bounded, namespace-aware XML codec.

openbim-dt is the lower-level vocabulary consumed by LOIN and independent data-template tooling. It does not depend on LOIN.

Implemented

• validated GUID, date-time, language/decimal, any-URI/reference, multilingual-text, rational, unit, data-type/value-list, and reusable ConceptType value contracts;
• owned subject, object-type, property, group, quantity-kind, reference-document, dimension, unit, and data-template contracts;
• a bounded strict XML 1.0 parser that rejects malformed namespace/content constructs, DTDs, and undeclared entities;
• semantic XML round trips retaining namespaces, ordering, comments, processing instructions, CDATA, and unknown attributes/elements;
• typed borrowed views and owned wrappers for the five concrete global roots and every local Library child family represented by the edition 2 XSD;
• structured built-in diagnostics separate from parsing;
• inspect, validate, and rewrite CLI commands.

This is not an XSD validator, complete clause-level conformance engine, ISO 23386 governance workflow, or ISO 12006-3 mapper. Byte-identical XML output is not claimed.

use openbim_dt::{Document, ElementKind};

let xml = r#"<dt:Library
  xmlns:dt="https://standards.iso.org/iso/23387/ed-2/en/"
  dt:GUID="11111111-1111-1111-1111-111111111111"/>"#;
let document = Document::parse(xml)?;
assert_eq!(document.root_kind(), Some(ElementKind::Library));
let output = document.to_xml_string()?;
assert_eq!(Document::parse(&output)?, document);
# Ok::<(), Box<dyn std::error::Error>>(())
