Setting up shared folders

In order to work through all of the steps in the tables below, you will need to set up two shared folders in Archivematica.

• The purpose of shared folders is to allow you to place digital objects into a folder on your host machine and have the objects automatically appear in a folder in Archivematica, and vice versa.
• The two folders in Archivematica which need to be set up as shared folders are /home/demo/ingestSIP and /home/demo/storeAIP.
  • /home/demo/ingestSIP is used to ingest SIPs from the host machine into Archivematica.
  • /home/demo/storeAIP is used to drop AIPs into a folder in Archivematica and have them appear back in the host machine.
  • These steps simulate the Producer dropping off SIPs for ingest and the Archivist transferring AIPs out of Archivematica for archival storage.
• For instructions on setting up shared folders, please go to Virtual appliance instructions.
• For testing purposes you can avoid setting up shared folders and simply use the test files found in /home/demo/testFiles/. However, you will not be moving SIPs into Archivematica or moving stored AIPs out of it.

Activity diagram 1 Receive SIP

File:Archivematica AD1 ReceiveSIP v1.pdf

Workflow diagram step	Description	Activity diagram references
Producer places SIP in shared folder on host machine	Place a folder of digital files into the shared ingest folder on the host machine.
SIP appears in shared folder in Archivematica	SIP will appear in /home/demo/ingestSIP/.	1.4 Receive SIP from Producer (UC-1.1)
Archivist copies SIP from shared folder to SIP receipt folder	Copy SIP from /home/demo/ingestSIP/ to /home/demo/receiveSIP/. /home/demo/ingestSIP acts as a backup SIP copy. If anything goes wrong during the ingest process, this backup copy can be retrieved and processed.

Activity diagram 2 Audit SIP

File:Archivematica AD2 AuditSIP v5.pdf

Workflow diagram step	Description	Activity diagram references
Archivist moves SIP from shared folder into quarantine	Drag the SIP from /home/demo/receiveSIP/ to /home/demo/quarantine.	2.1 Quarantine SIP
SIP is quarantined for 2 minutes	In a production system, SIPs would normally be quarantined for a set period of time (for example, four weeks), to allow anti-virus software to be updated with the latest virus profiles. A lock should appear on the SIP folder in quarantine. The archivist will not be able to read or modify the files during this time.	2.1 Quarantine SIP
SIP is scanned for malware	At the end of the quarantine period, ClamAV will automatically scan the files for viruses and other malware.	2.2 Check SIP for malware
Infected files are sent to possiblevirii folder	Infected files will appear in /home/demo/possiblevirii/. If this occurs, do not take any further steps in the ingest process. Inform the Producer that infected files have been found. It is recommended at this point to delete all SIP copies and request that the Producer take steps to review the causes of the problem and eventually resubmit a malware-free SIP.	2.4 Audit SIP for compliance 2.5 Assess SIP defiencies 2.6 Notify Producer of SIP rejection 2.8 Destroy SIP copies
Virus-checker report is sent to accessions folder	A report on ClamAV's virus scan will appear automatically: home/demo/accessionreports/virus.log.	2.4 Audit SIP for compliance

Activity diagram 3 Accept SIP for Ingest

File:Archivematica AD3 AcceptSIPforIngest v4.pdf

Workflow diagram step	Description	Activity diagram references
SIP contents are identified and validated using FITS	FITS (File Information Tool Set) is automatically launched once the quarantine period has ended and the files have been scanned for viruses. FITS incorporates format identification and validation tools such as DROID. JHOVE and the New Zealand Metadata Extractor, comparing the results of each tool and extracting a set of identification, validation and technical metadata. For more information on the FITS tool, see http://code.google.com/p/fits/	3.3 Identify formats (UC-1.2, step 3) 3.4 Validate formats (UC-1.2, step 3) 3.5 Extract metadata (UC-1.2, step 3)
Identification/validation reports are sent to accessions folder	The FITS report will appear in /home/demo/accessionreports/. The report appears as a folder with a 10-digit number; inside the folder is a report for each file in the SIP. Note that each report contains an MD5 checksum for the file.	3.3 Identify formats (UC-1.2, step 3) 3.4 Validate formats (UC-1.2, step 3) 3.5 Extract metadata (UC-1.2, step 3)
Accession log is sent to accessions folder	A report on the accession process will appear automatically: home/demo/accessionreports/accession.log. For each file in the SIP, the accession log will state "Accession of /tmp/accession-[FITS folder number]/[SIP number]/filename] completed successfully."

Activity diagram 4 Generate AIP

File:Archivematica AD4 GenerateAIP v2.pdf

Workflow diagram step	Description	Activity diagram references
SIP is moved to AIP preparation folder	At the end of the quarantine process, Archivematica automatically drops the SIP into /home/demo/prepareAIP	4.2 Add content information to AIP
Archivist normalizes files	From Archivematica's Linux desktop, open Xena Click Add Directory Select /home/demo/prepareAIP/[SIP]/ In Tools > Xena 4.2.1 Preferences > Xena destination directory enter /home/demo/prepareAIP/[SIP]. In Tools > Xena 4.2.1 Preferences > Xena log file enter /home/demo/accessionreports/xena_log. Click OK to close Xena 4.2.1 Preferences Click Normalise Wait for normalization process to be completed (a pop-up dialogue box will open indicating that the process has been completed). Click OK to close pop-up window Close Xena	4.3 Transform content information (UC-1.3, step 9)
Normalized files are saved to AIP preparation folder	In the SIP, look for files with the extension .xena. These are normalized versions of the original files. To view representations of normalized files, open the Xena Viewer from Archivematica's Linux desktop.	4.3 Transform content information (UC-1.3, step 9)
Normalization log is saved to accessions folder	A log file showing all the actions taken by Xena will appear: /home/demo/accessionreports/xena_log.0.
Archivist moves PDI in accessions folder to SIP in AIP preparation folder	In Archivematica, all the contents relating to the SIP in /home/demo/accessionreports/ is considered PDI (Preservation Description Information). Copy these contents to /home/demo/prepareAIP/[SIP]	4.5 Add PDI to AIP
Archivist moves SIP to AIP generation folder	Drag the SIP from /home/demo/prepareAIP/ and drop it into /home/demo/generateAIP/.
SIP content and PDI are zipped into AIP	A script called BagIt will run in the background, converting the SIP into a single zipped file. In Archivematica, this zipped file, which also includes metadata generated by the bagging process, constitutes the AIP. For more information about BagIT, see http://www.digitalpreservation.gov/library/challenge/data-transfer.html.	UC-1.3, step 10
AIP is moved to AIP receipt folder	The bagging process automatically moves the AIP to /home/demo/receiveAIP/. To view the AIP, double-click it. When it opens in a separate window, double-click it again; this will allow you to view (but not modify or delete) the contents of the zipped bag.
