Workflow diagram step	Description	UML diagram references
Producer places SIP in shared folder on host machine	The purpose of shared folders is to allow the Producer to drop SIPs into a folder on their host machine or network and have the SIPs automatically appear in a folder in Archivematica. For instructions on setting up shared folders, please go to Virtual appliance instructions. Neither the folder name nor any of the filenames should include spaces or special characters. Underscores are ok. Make the shared folder in Archivematica /home/demoreceiveSIP/. For testing purposes you can avoid setting up shared folders and simply use the test files found in /home/demo/testFiles/.
SIP appears in shared folder in Archivematica	SIP will appear in /home/demo/receiveSIP/. If using files from /home/demo/testFiles/, copy a folder from /testFiles/ into /home/demo/receiveSIP/.
Archivist copies SIP from shared folder to SIP backup folder	Copy the SIP in /home/demo/receiveSIP/ and paste it into /home/demo/receiveSIPbackup/. If anything goes wrong during the ingest process, this backup copy can be retrieved and processed.

Archivist moves SIP from shared folder into quarantine	Drag the SIP from /home/demo/receiveSIP/ to /home/demo/quarantine.
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.
SIP is scanned for malware	At the end of the quarantine period, ClamAV will automatically scan the files for viruses and other 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.

Workflow diagram step	Description	UML 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 File Information Tool Set (FITS) [http://code.google.com/p/fits/ File Information Tool Set (FITS)
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.
Virus-checker report is sent to accessions folder	A report on ClamAV's virus scan will appear automatically: home/demo/accessionreports/virus.log.
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."
