Transfer tab
| Micro-service | Description |
|---|---|
| Approve transfer | Once the transfer has all its digital objects and has been formatted for processing, the user selects "Transfer complete" from the Actions drop-down menu. |
| Verify transfer compliance | Verifies that the transfer conforms to the folder structure required for processing in Archivematica. The structure is as follows: /logs/, /metadata/, /metadata/submissionDocumentation/, /objects/. |
| Rename with transfer UUID | Adds a unique universal identifier to the transfer folder name. |
| Include default Transfer processingMCP.xml | Adds defaultTransferProcessing.xml file from /sharedDirectoryStructure/sharedMicroServiceTasksConfigs/ to the transfer directory. This xml file can configure workflow options such as creating transfer backups, quarantining the transfer and selecting a SIP creation option. |
| Workflow decision - create transfer backup | The user can choose to create a complete backup of the transfer in case transfer or ingest are interrupted or fail. The transfer backup is placed in /sharedDirectoryStructure/transferBackups/ and will automatically be deleted once the AIP has been moved into storage. |
| Assign file UUIDs to objects | Assigns a unique universal identifier to each file in the /objects/ directory. |
| Assign checksums and file sizes to objects | Assigns a sha-256 checksum to each file in the /objects/ directory and calculates file sizes. |
| Verify metadata directory checksums | Checks any checksum files that were placed in the /metadata/ folder of the SIP prior to ingest. Note that the filenames need to be named based on their algorithm: checksum.sha1, checksum.sha256, checksum.md5. |
| Generate METS.xml document | Generates a basic mets file with a fileSec and structMap to record the presence of all objects in the /objects/ directory and their location in any subdirectories. Designed to capture the original order of the transfer in the event the user chooses subsequently to delete, rename or move files or break the transfer into multiple SIPs. The mets file is automatically added to any SIP generated from the transfer. |
