Same Question here.

This data is only the field definition, which is basically the declaration that "this is a field, this is what it's called, these are its global and per instance settings and their default values, and it uses this widget and formatter by default". These are not Form API "fields" (those are defined using hook_element_info()), but fields attached to Entities. An Entity field's widget is usually composed of one or more Form API elements.
