Fields§

§dataset_url: String

§change_type: ChangeType

What kind of change occurred.

§affected_graph: Option<String>

The named graph affected (if applicable).

§added_triples: Vec<(String, String, String)>

Triples that were added (subject, predicate, object as strings).

§removed_triples: Vec<(String, String, String)>

Triples that were removed (subject, predicate, object as strings).

§timestamp: SystemTime

When the change occurred.

§change_id: String
