Models/Replication

A Replication request serves as the primary data structure a node looks at when attempting to replicate a bag. It contains (most of) the information necessary to replicate a bag and verify that it was successful.

Replication

Field	Type	Description
id	Long	The ID of the Replication
createdAt	DateTime	The time of creation
updatedAt	DateTime	The last time the Replication was modified
status	ReplicationStatus	The status of the Replication
bagLink	String	URI to download the bag
tokenLink	String	URI to download the token store
protocol	String	The protocol to use for replication
receivedTagFixity	String	The computed fixity of the Bag (currently the sha256sum of the tagmanifest)
receivedTokenFixity	String	The computed fixity of the TokenStore (currently sha256)
node	Node	The replicating Node
bag	Bag	The bag being replicated

ReplicationStatus

Enumerated type describing the current state a replication request is in.

PENDING - Set by the Ingest-Server. A request has been made and is waiting for acknowledgement/transfer.
STARTED - Set by the Replicating Node. Acknowledges the existence of a transfer, and replication is likely queued if not started.
TRANSFERRED - Set by the Ingest Server. Both the transfer of the ACE Token Store and Bag have been completed and are valid.
ACE_REGISTERED - Set by the Replicating Node. The collection has been registered in ACE.
ACE_TOKEN_LOADED - Set by the Replicating Node. The token store has been uploaded to the collection in ACE.
ACE_AUDITING - Set by the Replicating Node. The collection in ACE is auditing.
SUCCESS - Set by the Replicating Node. Acknowledges that the ACE audit was successful.
FAILURE_TOKEN_STORE - Set by the Ingest-Server. The received fixity value for the token store was incorrect.
FAILURE_TAG_MANIFEST - Set by the Ingest-Server. The received fixity value for the tagmanifest was incorrect.
FAILURE - Set by the Replicating Node. There was a general failure in transfer of the content.
