Using the entities feature

1. What is the issue? Please be detailed.

The entities feature availableon the new version of ODK is promising. And we have started experimenting with its use.

We are using a Farmer Registration form submissions to create entities that will be used for follow up surveys.

Is there any way we can use the metadata of the Farmer Registration submissions like the instanceID or Key in the entities data so that we can relate follow up surveys to the Farmer Registration submissions?

There is an __id in the entities data called Entity ID but this is a hash only for the entities table.

Is there any suggestion on how wecan relate the entities data to the original submissions?

2. What steps can we take to reproduce this issue?

3. What have you tried to fix the issue?
