Major Description
Currently classifications and business glossary terms in Apache Atlas are treated as being valid permanently in Ranger. There are use cases where such classifications are time bound based on customer input (such as financial information about earnings that is sensitive and restricted only until the earnings release) (i.e) either be effective after a certain date/time and/or expire after a specific date/time or valid only during an interval from a start date/time to an end date/time
Ranger policy engine needs to be able to recognize the start and end times for tags/classifications received from Apache Atlas via tag sync and enforce tag-based policies depending on attributes of the tags that represent its validity period.
