|Update view, transactions and snapshots|
The update semantics of the RDF database follows the conventional Prolog logical update view. In addition, the RDF database supports transactions and snapshots.
rdf_transaction(Goal, user, ). See rdf_transaction/3.
rdf_transaction(Goal, Id, ). See rdf_transaction/3.
Processed options are:
true, which implies that an anonymous snapshot is created at the current state of the store. Modifications due to executing Goal are only visible to Goal.
snapshotoption. A snapshot created outside a transaction exists until it is deleted. Snapshots taken inside a transaction can only be used inside this transaction.
