Alembic mesh import and operation

I have been reading about alembic import here https://docs.blender.org/api/current/bpy.ops.wm.html

Is there example code which illustrate how one can get information about the imported geometries e.g. getting the bounding box?

Additionally, can we apply transformation e.g. translation and rotation ? If so, how should one go about doing that ?

Cheers
