Consistent graph replication - RDF Dataset Canonicalization #101

Closed sandervd closed 6 months ago

sandervd commented 6 months ago

When a client requires hard guarantees on consistency, the logic described in the RDF Dataset Canonicalization could be used to provided hashes of the state that should be reached after applying a fragment, or even better, a transaction. This becomes relevant in cases where LDES is used as a replication protocol for named graphs (the client should have an exact copy of the named graph the publisher intended). For instance, consistency could be lost if a client is offline longer than allowed by the retention period, which could result in missed delete operations (tombstone events). If a checksum mismatch is detected, the client must restart replication from the start of the log to arrive at consistent state.

Closing as wrongfully created in tree, LDES concern.
