Everyone's A Mechanic: Building a Simple E-
records workflow

Are e-records worth it?
Well, *I* think so... Improved access to content
More information about context
Increased manipulability for research analysis
BUT... Sheer volume increases opacity
Digital preservation and "dark ages"
Time and Money for new systems (?)
Where would we like to be with E-records?

The Mechanic Metaphor
Borrowed from a Helen Tibbo talk at Purdue University, September 2012
“In the early days of the automobile, everyone was a mechanic.”
The scary implication: You have to know enough about your process to fix thingsThe exciting implication: You can make it as simple or as complex as you need
What's standing in our way?
Uncertainty re: appropriate procedures Unfamiliarity with e-records tools and systems Unfamiliarity with e-records as a medium Perceived complexity of metadata and/or preservation requirements/systems
The common thread: letting the perfect be the enemy of the good!
Dirty Little Secret about e-records:
You already know how to do this! Accessioning: gain intellectual/physical
control, identify potential problems Arrangement: Put files in series/other logical
order Description: Provide access at various levels
of the collection Preservation: Ensure the ongoing
integrity/usability of the materials
The Local Catalyst/Example Office of the Chancellor
Records from personal and office computers Various file types and formats Some pre-appraisal by office staff and archivists Large volume of files– automation a must
The desired end product: an AIP! Short-Term: Provide basic description and
preservation metadata Long-Term: Prepare for ingest into future repository
The following worked for us, but… The tools that work for us may not be the best for *your* needs!
Take stock of your own e-records holdings Browse tool catalogs/reviews and experiment Document what you did to your files and why
The “Chewing Gum/Baling Wire” approach Different tools gather complementary data
…But check outputs for redundancies One tool’s failure won’t bring down the whole
thing (probably)
Accessioning and Pre-appraisalGoals: Establish authenticity, perform collection overview and QCDuke Data Accessioner
Quick and easy checksum generation Basic technical metadata for PREMIS—XML
format DROID and/or JHOVE
File Format Identification and validation DROID reporting gives overview of collection Initial triaging for preservation?
The Working Copy Watershed
From this step on, minimize changes to your originals:
Create a working copy for weeding/ arrangement
Write-protect originals!
Creating a disk image (*.iso, *.uif, etc.) may be helpful for preserving fixity here
See also digital forensics tools for increased authenticity
Appraisal and Arrangement Goals: Move files to reflect logical order, identify/restrict confidential infoFreeCommander (and family)
Two-pane browsing– easy arrangement integrated viewer for quick appraisal
Firefly SSN Finder Identifies Social security, credit card #s, other
sensitive info Supplements, not replaces, manual inspection
Description: File LevelGoals: extract technical/descriptive metadata automatically; improve discovery EXIFTool
Pulls embedded metadata from files (esp. photos) Exports data into CSV for tabular description
ReNamer Standardize file names, strip special characters Option to add embedded metadata to filenames
n.b. Automation is especially key for this step. (Think MPLP!)
File-Level Description Table
Description: Collection LevelGoals: discovery of collection as a whole No special tools necessary- Describe as you would paper records! That said, a few EAD considerations...
<phystech> should include hardware, OS, and software needed to render all formats
Describe at series/folder, not file, level Consider IP and/or confidentiality issues if including
digital object links
Preservation Goal: Avoid obsolescence and/or technology failureDigital Preservation Software Platform
Normalizes files to preservation formats Logs every preservation action taken
n.b. Use this *in addition* to other metadata gathered.
File Storage Location Use stable media or network storage (backed
up) -- i.e. *not* CDs, floppies, etc. Best practice: 2 onsite copies, 1 offsite copy
XENA AIP Example
Putting it all together Determine needed metadata for
preservation/access Delete extraneous output
Collocate if you can (XSLT, etc.); document what's where if you can't
Provide access to as much or as little metadata as you need
Keep the originals for authenticity Access copies for everyday usage

And don’t forget…
Digital preservation, like car maintenance, is an ongoing process.
Know your collections
Have a monitoring plan
Keep up with best practices, discussions
Don't give up! Anything you can do is helpful.
I hated this car… but it got me to my destination. (Most of the time.)
