Data Format in Cloud


What is the best way to store and reuse building data in Cloud? In which format should they be saved?
json, obj, or ?

Data example: walls, floors; and their properties. The data that I need to store is from Rhino or Archicad, and will be used from similar software too.

Thank you very much in advance,

Sounds to me like you should be using BIM. You can use BIMCloud from ArchiCAD and I think you can use it in Rhino with VisualARQ, but I have not tried that.
