This repository contains JSON templates that can be executed on the Apache Atlas API for creation of custom type defintions
This folder contains
1. full_model [folder] --> which contains artifacts to create the final model in Apache Atlas.
2. person_entity_def.json --> person_entity_def.json
Below is the example of our model. We have a system instance called cp_system that is owned by a person (aka cp_person) and contains folders of type cp_folder where we store files of type cp_files, each of which includes worksheets of type cp_worksheet that enable us to store tabular data with columns of type cp_column. The entities are also connected, giving each link a different name.

Once the model is created, we need to push data using rest API interface. We can learn more about them on the blog post itself.
