openbim-mmcSafe MMC 2.0 mechanics for Rust

Bounded archives, namespace-aware XML, deterministic construction, and an explicit DIN 18290 scope boundary.

Defensive archive handling
Bound actual decompressed output, reject ambiguous or hostile paths, and extract without following symlinks or overwriting files.
Typed without discarding source
Inspect MultiModel and LinkModel structures while retaining exact source XML, opaque payload entries, and original archive bytes.
Deterministic construction
Build public MMC 2.0 schema-shaped documents and reproducible ZIP archives through a typed Rust API.
Honest standards boundary
Public MMC 2.0 mechanics are implemented; complete conformance with every current licensed DIN edition is not claimed.

Container mechanics, not payload semantics

openbim-mmc reads, validates, extracts, and constructs Multi-Model Container archives used in DIN 18290 workflows. IFC, GAEB, PDF, and other application resources remain opaque. Domain profiles combine this crate with their own maintained format libraries rather than coupling every payload parser into the container core.

Start with the getting-started guide, then read the capability and preservation contract.
