Recommended approach

First, ask yourself the following questions:

1. Which metadata forms do you need?
2. Which fields and settings do you want the metadata forms to have?
3. Which fields do you want to use in multiple metadata forms?

Then, proceed as follows:

1. First, create all the field templates.

2. Next, create the metadata forms.

3. Now, add the fields to the metadata forms.

Information

You need to create the field templates required for the metadata forms before you create the metadata form. You can use field templates in different metadata forms.
