Hi Steve,

You can take a look at this [link](https://docs.ansible.com/ansible/latest/dev_guide/developing_inventory.html#inventory-cache). Also, simplest example of this implemented in [virtualbox inventory plugin](https://github.com/ansible-collections/community.general/blob/main/plugins/inventory/virtualbox.py).
