Transfer
Micro-service | Description |

BitCurator - Image source media
|
User starts transfer by imaging the source media at the beginning of the transfer process. Image is an Archivematica transfer type. |
Approve Transfer
Set file permissions |
This is the approval step that moves the transfer into the Archivematica processing pipeline. |
Verify transfer compliance
|
Moves the transfer to a processing directory based on selected transfer type (standard, zipped bag, unzipped bag, DSPace export or maildir). Verifies that the transfer conforms to the folder structure required for processing in Archivematica and restructures if required. The structure is as follows: /logs/, /metadata/, /metadata/submissionDocumentation/, /objects/. |
Rename with transfer UUID
|
Directly associates the transfer with its metadata by appending the transfer UUID to the transfer directory name. |
Include default Transfer processingMCP.xml
|
Adds a file named processingMCP.xml to the root of the transfer. This is a configurable xml file to pre-configure processing decisions. It can configure workflow options such as creating transfer backups, quarantining the transfer and selecting a SIP creation option. |
Assign file UUIDs and checksums
|
Assigns a unique universal identifier and sha-256 checksum to each file in the /objects/ directory. |
Verify transfer checksums
|
Checks any checksum files that were placed in the /metadata/ folder of the transfer prior to moving the transfer into Archivematica. |
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 locations 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. A copy of the METS file is automatically added to any SIP generated from the transfer. |
Extract packages
|
Extracts objects from any zipped files or other packages. Extracts attachments from maildir transfers. |
Scan for viruses
|
Uses ClamAV to scan for viruses and other malware. If a virus is found, the transfer is automatically placed in /sharedDirectoryStructure/failed/ and all processing on the transfer is stopped. |
Clean up names
|
Some file systems do not support unicode or other special characters in filenames. This micro-service removes prohibited characters and replaces them with dashes. Original filenames are preserved in the PREMIS metadata. |
Characterize and extract metadata
|
Identifies and validates formats and extracts object metadata using the File Information Tool Set (FITS). Also identifies file extensions, which are used for selecting normalization paths. |
Complete transfer
|
Indexes transfer contents, then marks the transfer as complete. |
Create SIP from Transfer
|
This is the approval step that moves the transfer to the SIP packaging micro-services (Ingest). |
Ingest
Micro-service | Description |
---|---|
Verify SIP compliance
|
Verifies that the SIP conforms to the folder structure required for processing in Archivematica. The structure is as follows: /logs/, /metadata/, /metadata/submissionDocumentation/, /objects/. |
Rename SIP directory with SIP UUID
|
Directly associates the SIP with its metadata by appending the SIP UUID to the SIP directory name. |
Include default SIP processingMCP.xml
|
Copies the processing config file added to the transfer in Include default Transfer processingMCP.xml, above, to the SIP. |
Remove cache files
|
Removes any Thumbs.db files. |
Normalize
|
Determines which normalization options are available for the SIP and presents them to the user as choices. Normalizes (i.e. generates preservation and/or access copies) based on selection. Thumbnail files are also generated during this micro-service. |
Process submission documentation
|
Processes any submission documentation included in the SIP and adds it to the /objects/ directory. |
Prepare DIP
|
Creates a DIP containing access copies of the objects, thumbnails and a copy of the METS file. |
Upload DIP
|
Allows the user to choose to upload the DIP to either ICA-AtoM or CONTENTdm. |
Upload DIP to ICA-AtoM
|
The user uploads the DIP to a selected description in ICA-AtoM. |
Upload DIP to CONTENTdm
|
The user uploads the DIP to a selected description in CONTENTdm. |
Prepare AIP
|
Creates an AIP in Bagit format. Indexes the AIP, then losslessly compresses it. |
Store AIP
|
Moves the AIP to /sharedDirectoryStructure/www/AIPsStore/ or another specified directory. Once the AIP has been stored, a copy of it is extracted from storage to a local temp directory, where it is subjected to standard BagIt checks: verifyvalid, checkpayloadoxum, verifycomplete, verifypayloadmanifests, verifytagmanifests. |
