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/.
Include default SIP processingMCP.xml

Include default SIP processingMCP.xml

Includes a file named processingMCP.xml in 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.
Remove cache files

Remove cache files

Removes any Thumbs.db files

Check for Service directory
Check for Access directory
Find options to normalize as
Create DIP directory
Normalize access
Normalize preservation
Remove files without linking information (failed normalization artifacts etc.)
Create thumbnails directory
Normalize thumbnails
Verify checksums generated on ingest
Approve normalization

Determins which normalization options are available for the SIP and presents them to the user as choices. Normalizes based on selection.
  • Creates access copies to be added to the DIP.
  • Creates preservation copies to be included in the AIP along with the original files.
  • Creates thumbnail files.

If desired, the user can verify the quality of normalized files in /sharedDirectoryStructure/watchedDirectories/approveNormalization/.

Process submission documentation

Check for submission documentation
Copy transfer submission documentation
Move to processing directory
Set file permissions
Assign file UUIDs to submission documentation
Assign checksums and file sizes to submissionDocumentation
Extract packages in submission documentation
Sanitize file and directory names in submission documentation
Scan for viruses in submission documentation
Characterize and extract metadata on submission documentation
Identify Files ByExtension
Normalize submission documentation to preservation format

Prepare DIP

Copy thumbnails to DIP directory
Copy METS to DIP directory
Set file permissions
Generate DIP

Create the DIP with copies of the METS file, and thumbnails. Moves the DIP to the upload DIP watched directory.
Prepare AIP

Copy transfers metadata and logs
Remove files without linking information (failed normalization artifacts etc.)

Select compression algorithm
Select compression level
Compress AIP
Set bag file permissions
Removed bagged files

Create an AIP in Bagit format. Index the AIP, then losslessly compress it.
Store AIP

Move to the store AIP approval directory
Store AIP
Store AIP location
Store the AIP

Moves the AIP to a specified directory. In the demo version of Archivematica the directory is /sharedDirectoryStructure/www/AIPsStore/. In other environments it can be a remote network mounted directory. The directory structure of the AIP store contains UUID quad directories and an index.html file listing the AIPs in storage. The index.html file is displayed in the dashboard in the Archival storage tab.

Once the AIP has been stored, a copy of the AIP is extracted from storage to a local temp directory, and is validated with the various BagIt checks: verifyvalid, checkpayloadoxum, verifycomplete, verifypayloadmanifests, verifytagmanifests.

Upload DIP to contentDM

Restructure DIP for CONTENTdm upload
Select upload type (Project Client or direct upload)
Select target CONTENTdm server
Get list of collections on server
Select destination collection
Upload DIP to contentDM
Move to the uploadedDIPs directory

It is now possible to upload to ContentDM.
