PointSav Documentation

The engineering library for the PointSav platform — operating systems and services for regulated businesses that own their data, their AI, and their record-keeping outright. Where the monorepo holds the code, this wiki holds the reasoning: architecture, services, security, and the governance commitments that bind future development.

The Flat-File BIM Leapfrog

The Flat-File BIM Leapfrog

PointSav’s Building Design System achieves a structural competitive advantage by adopting five architectural constraints that are individually simple but collectively occupy a market category hyperscalers cannot enter without cannibalizing their own revenue models. By prioritizing flat-file storage, open standards, a Rust-based offline-first architecture, and the EUPL license, Foundry delivers a BIM substrate that is inherently owned by the asset holder rather than rented from a cloud vendor.

Structural Constraints as Competitive Moat

The strategy is predicated on five foundational architectural decisions:

  1. Flat-File Storage: All building data resides in human-readable, plain-text files.
  2. Open Standards: Strict adherence to ISO-standardized IFC, IDS, and BCF.
  3. Rust + Tauri: A high-performance, memory-safe execution environment.
  4. Offline-First: Full functionality without mandatory internet connectivity.
  5. EUPL-Licensed: Open-source legal protection that is procurement-friendly for governments.

Production Maturity of the Open BIM Stack

As of 2024, the open BIM standards stack has reached sufficient maturity for commercial-grade infrastructure. IFC 4.3 (ISO 16739-1:2024) extends the schema from buildings to civil infrastructure, including bridges, rail, and waterways. The canonical serialization (IFC-SPF) remains a plain-text format (ISO 10303-21) that is readable in any standard text editor.

Foundry canonicalizes on IFC-SPF today, with intended opportunistic mirroring to ifcJSON. While IFC 5/IFCX is in development, the PointSav architecture is designed such that future migration is intended to be a serialization swap rather than a core rewrite.

Flat-File Definition and Taxonomy

"Flat-file BIM" refers to a directory of plain-text and standardized binary files accessible without proprietary SDKs.

Format Standard Role
IFC-SPF (.ifc) ISO 16739-1:2024 Authoritative geometry + semantics
IDS 1.0 buildingSMART (2024) Validation contract
BCF 3.0 buildingSMART Collaboration history
Per-element YAML Local Convention Sensor and work-order metadata
glTF 2.0 ISO/IEC 12113:2022 Visualization cache

The .ifc file serves as the authoritative spatial state, while YAML sidecars handle dynamic data such as sensor readings and lease references.

Five Differentiated Capabilities

1. Asset-Anchored BIM

The digital twin travels with the property deed. Unlike multi-tenant SaaS models where data is "rented," a flat-file twin is owned like the physical building—permanently and transferably.

2. Offline-Capable Field Operations

By construction, cloud-authoritative twins are unusable in air-gapped facilities, basements, or remote construction sites. Foundry preserves full BIM functionality without network dependency.

3. Vendor-Obsolescence Survival

Buildings have a 50-year lifespan; proprietary formats often last fewer than five. A flat-file substrate ensures data remains readable for decades after the software vendor disappears.

4. Direct IoT Integration

Per-element YAML sidecars ingest sensor data via local MQTT brokers. This eliminates sensor-count-based token charges and satisfies strict data residency requirements (GDPR, HIPAA).

5. Unified Asset Archive

The building, lease, and ledger converge into a single portable archive. The Totebox Archive is the first architecture where a building’s legal, financial, and spatial identity are a single, portable artifact.

Regulatory and Security Alignment

The architecture satisfies mandatory open-standard requirements for US federal agencies (GSA, VA), EU member states, and Singapore’s CORENET X. It is uniquely positioned to meet ITAR air-gapped requirements and EU Data Act sovereignty mandates.

Strategic Trade-offs

PointSav acknowledges that real-time multi-user design workshops are currently faster in synchronous cloud SaaS. Additionally, while the substrate is designed to be AI-ready, a generative BIM authoring tool is not planned for the v0.0.1 release. These are deliberate trade-offs to prioritize an offline-first, vendor-independent posture.
