  • Strict typed documents

    Model the fixed mvdXML 1.1 vocabulary, namespace, ordering, identities, references, and cardinalities as Rust data.

  • Defensive XML handling

    Apply byte, depth, event, and text budgets before typed deserialization, with no DTD processing or network access.

  • Complete rule language

    Parse and evaluate parameter comparisons, metrics, regexes, groups, connectives, and nested TemplateRules against values supplied by an adapter.

  • Honest execution boundary

    Validate MVD documents and rule inputs without claiming IFC graph traversal, concept execution, generic XSD validation, or bundled standards assets.

Scope at a glance ​

openbim-mvd is a Rust library for mvdXML 1.1 documents. It can parse, write, validate, and evaluate rule trees when the caller supplies values. It does not open IFC models, traverse entity graphs, extract template parameters, or decide whether an IFC model satisfies an MVD.

The project is pre-release at 0.1.0. Begin with getting started, then use the capability matrix to check each boundary before integrating it.

Implementation licensed under AGPL-3.0-or-later. Official standards material is not redistributed.
