Technology

The technology stack and data ecosystem used to build IFCWebServer.org consists of different programming languages, databases and tools.

IFCWebServer

The core of the data server which for parsing and processing of IFC models is built using the Ruby programming language. Which is a powerful script language and has unique features like the Meta programming.

BIM Viewer

The online BIM Viewer uses HTML, Java script, CSS for the GUI and front-end and PHP for the server side.

Some JS libraries which have been used:

• jQuery
• Threejs
• Chart.js

Databases

For the data management we use dual DB system:

• SQLite for managing the BIM information of single models in simplified way
• Neo4j as a graph database for central management of many BIM models to offer advanced functions like building topology analysis and compare model versions

For processing IFC geometry we use:

• IFCOpenshell.org
• Blender
• Python language
