Major Description
It would be nice to be able to do fine-grained access control (FGA) over nested structures, e.g., the JSON responses of API calls. This requires the individual attributes in a JSON object to be first-class metadata objects which can be tagged and on which policies can be written. We have built a plugin and the corresponding Apache Atlas metadata structures and tagsync-mapper to support TBAC/RBAC/ABAC FGA over JSON structures. Our instigating use case was FGA over the JSON responses of API calls, but this plugin has potential value anywhere FGA over the individual attributes of nested structures is needed, eg JSON messages read from Kafka topics.
