The Meta-Example package contains the example tables and models that will be referenced in other experiences.
The other experiences (such as forms and reports) contain examples to help you get acquainted with the process, and these examples need the Meta-Examples tables in order to work.
You only have to start with deploying Meta-Examples, only if Meta-Forms was deployed on your Cinchy environment after November 2021.
Once you extract either Meta-Forms or Meta-Reports packages, you will see the respective App Experience, Data Experience, as well as the Meta-Examples experience.
