File format building blocks: primitives in digital preservation

A primitive in software development can be described as:

a fundamental data type or code that can be used to build more complex software programs or interfaces.

– via https://www.capterra.com/glossary/primitive/ (also Wiki: language primitives)

Like bricks and mortar in the building industry, or oil and acrylic for a painter, a primitive helps a software developer to create increasingly more complex software, from your shell scripts, to entire digital preservation systems.

Primitives also help us to create file formats, as we’ve seen with the Eyeglass example I have presented previously, the file format is at its most fundamental level a representation of a data structure as a binary stream, that can be read out of the data structure onto disk, and likewise from disk to a data structure from code.

For the file format developer we have at our disposal all of the primitives that the software developer has, and like them, we also have “file formats” (as we tend to understand them in digital preservation terms) that serve as our primitives as well.

The sensitivity index: Corrupting Y2K

In December I asked “What will you bitflip today?” Not long after, Johan’s (@bitsgalore) Digtial Dark Age Crew released its long lost hidden single Y2K — well, I couldn’t resist corrupting it.

Fixity is an interesting property enabled by digital technologies. Checksums allow us to demonstrate mathematically that a file has not been changed. An often cited definition of fixity is:

Fixity, in the preservation sense, means the assurance that a digital file has remained unchanged, i.e. fixed — Bailey (2014)

It’s very much linked to the concept of integrity. A UNESCO definition of which:

The state of being whole, uncorrupted and free of unauthorized and undocumented changes.

Integrity is massively important at this time in history. It gives us the guarantees we need that digital objects we work with aren’t harboring their own sinister secrets in the form of malware and other potentially damaging payloads.

These values are contingent on bit-level preservation, the field of digital preservation largely assumes this; that we will be able to look after our content without losing information. As feasible as this may be these days, what happens if we lose some information? Where does authenticity come into play?

Through corrupting Y2K, I took time to reflect on integrity versus authenticity, as well as create some interesting glitched outputs. I also uncovered what may be the first audio that reveals what the Millennium Bug itself may have sounded like! Keen to hear it? Read on to find out more.

Unrealized ideas: Unintentional Secrecy in the Era of Openness

Tyler recently posted this quote:

“History unprocessed is opportunity unrealized”

It reminds me of an unrealized article I wasn’t able to get written and into the wild, but it’s an important thought I would like to share nonetheless.

Proposed for James Lowry’s ACARM Symposium in 2015, I wanted to discuss when government is unable to adequately fund day-to-day effort, and research and development in the archive sector, leading to inefficient and potentially ineffective processing pipelines for records of archival value accessioned from government agencies and commissions.

It was just an abstract, but maybe folks have thoughts about this? Have we moved on since the early to mid 2010’s? What modern metrics do we have available to us today to see the progress? What does the advent of the new US administration mean for issues like this? As well as increasing worldwide authoritarianism?

Interviewing in digital preservation: a duty of care and community

Sometime in 2024, I received zero feedback for a job interview—one of at least five interviews without any feedback in the last eight years.

The thing is, digital preservation is very niche. Those five roles probably represent a good number of institutions actually hiring specialists and likely represent some of the best chances for jobs in the future.

Not getting a role is part and parcel of interviewing, but in not providing feedback, a didactic moment was lost—a moment of community connection and outreach—and simply an act of care.

Furthermore, loops are not closed, processes feel incomplete, and of course, you will likely know the person who gets the role ahead of you. Trying to measure yourself against that individual will likely be in the back of your mind when you next meet or work with these individuals because you have been left questioning by the recruiter.

And before it is suggested that this is just a ‘you’ thing—let’s say conservatively, five people interviewed for each of the five positions I applied for. Assuming everyone is treated equally, that’s 20 people missing out on something critical to improving their skill set, interview technique, or helping them find more suitable jobs in the future. I guarantee, you ALL deserve feedback. It is also 20 people that each recruiter has missed an active opportunity to build a stronger bond with, who will sing the praises of the process and the organization; this is important.

What we could do with a second life…

Cleaning up some posts today for clarity or for improving their appearance in ActivityPub instances I didn’t want to lose this quote introduced to us at Archives New Zealand in a visit from Verne Harris back in 2017. It represents the need for a second life to apply all of the lessons learned in this one – in the GLAM sector, everything we learn getting up to speed, to learn how to work within our institutional boundaries, to align with corporate strategy, or just to hustle to have our work recognized and valued.

My colleague Andrea references the quote a lot and I am often reaching to recall it.

We work in the dark – we do what we can – we give what we have. Our doubt is our passion, and our passion is our task. The rest is the madness of art. – Henry James, The Middle Years
