Version Based Retention Policy
https://w3id.org/ldes#LatestVersionSubset
To keep the Event Stream clean with less history, the Version Based Retention Policy allows to only keep a certain amount of versions of a state object (referenced through ldes:versionOfPath
).
The amount of version to retain can be set as a number (higher than 0).
Example
@prefix ldes: <https://w3id.org/ldes#> .
@prefix tree: <https://w3id.org/tree#>.
