How to get all datasmith objects into BP

How to get all datasmith objects into BP and then also how to get the metadata from them?.
The help is unclear on all subjects.

What is datasmith scene and how do i get it into BP?.
I find visual programming easy, but not in unreal for some reason. I have problem getting my objects into BP.
