@sergej Yes, this is why I’ve focused on IFC
I have a R&D project called "INSIDE THE CIRCULAR PRODUCT FOR LIVING" - BRINGING A NEW VISION TO THE BUILT ENVIRONMENT BY THINKING OF “BUILDING AS A CIRCULAR PRODUCT”
So I started with a question: Do you know any classification format for expanding BIM with PLM?
And checked many classifications like OmniClass, Masterformat, Uniformat, UniClass and CoClass and finally realized that: If I want a classification which covers BIM+PLM (BLM) and Circular Economy I have to develop a new classification
Then came with this idea: Building Classification - More Granular
But finally have focused on ODClass [ReaserchGate][GitHub] which is the first step to not only rebuild IFD and IFC structure, but also develop a classification which solves big issues in the Built Environment Industry
Just I want to have “Sets” too
