## Meet the Team

* **Milovann Yanatchkov** : bug-hunter, aec-free-rider, associate-professor, kebab-case-lover.
* **Artem Igumnov** : civil-engineer, aec-ice-breaker

## The Challenge

* [Problem statement](https://github.com/vyzn-tech/ifc-data-bus?tab=readme-ov-file#problem-statement)

## Problem Statement

* Architects and planners rely on a **broad ecosystem of software tools**,
* yet **poor data integration between these tools creates major bottlenecks** in the design process.
* This fragmentation prevents holistic project optimization and slows down coordination.

### Data Stream 

* Although **OpenBIM** ✅ aims to support **interoperability**, it still lacks robust mechanisms for

> **bi-directional data exchange** ✅

* —particularly when it comes to **re-integrating data into CAD and CDE environments**.
*  **Existing initiatives often do not prioritize full OpenBIM compliance**, leaving a clear opportunity for alternative, standards-aligned solutions.

### 'Flat Modules' vs 'Monolithic Blob'

> At the same time, the emerging **modularized and layerized IFC5** standard ✅

* introduces new capabilities for more flexible, **fine-grained**, and machine-friendly data handling.
* These advances open the door to **new workflows** built around decentralized, **event-driven data exchange** rather than **monolithic file transfers**.
