The constraints are flat-file storage, open standards, Rust + Tauri, offline-first, and EUPL-licensed. The open BIM standards stack matured between 2023 and 2025 into the infrastructure that makes this strategy viable; the property-manager market gap is documented in peer-reviewed literature; and the open toolchain is commercial-grade today.

This document explains what flat-file BIM is, what it is not, and why five specific capabilities follow from the architecture rather than needing to be added on top. @@ -72,7 +72,7 @@ The workplace application family — `app-workplace-memo`, `app-workplace-presen The format stack — IFC-SPF + IDS 1.0 + BCF 3.0 + COBie — fulfills mandatory open-standard delivery requirements across US federal (GSA, USACE, VA, NAVFAC), EU member states (Germany, Italy, Spain, Denmark, Norway, Netherlands, Poland), the UK BIM Framework, Singapore CORENET X (mandatory October 2026), Dubai (mandatory since January 2024), and the broader buildingSMART openBIM movement.
