Timebased Retention Policy

https://w3id.org/ldes#DurationAgoPolicy

Similar to the Point in Time Retention Policy, the Timebased Retention Policy will filter out members based on their ldes:timestampPath. The difference between the previous retention policy is that the Timebased one works with a sliding window, rather than a hard-set value.

The sliding window can be defined with a ISO 8601 Temporal Duration. Any members’ ldes:timestampPath that falls outside of this range will be removed.
