Declarative all the way down: Building PRONOM signatures with JSONID

PRONOM signatures are a form of declarative language, you describe the anticipated behavior in PRONOM’s regular expression syntax and tools like DROID, FIDO, and Siegfried will interpret those instructions and attempt to match them against different files to return a file format identification.

Normally, you will write PRONOM signatures by hand but doing so for file formats based on other file format building blocks can lead to inconsistencies. Bertrand Caron previously also recognized this in the XML formats that are described with PRONOM signatures on Wikidata.

XML can use single quotes ‘ (hex: 0x27) and double quotes ” (hex: 0x22) for attribute data, and so, do we make a PRONOM signature with multiple sequences anticipating the use of either?

The answer is more often than not likely to be yes, because the appearance of these values are often helpful for identifying boundaries for strings that we know must exist.

But the more file formats that we need to add to PRONOM that are based on foundational formats like XML, or JSON, or similar, the more inconsistencies will creep in, such as sequences that are looking specifically for one byte sequence over another.

The issue extends further if file formats allow data to appear at the beginning of file, or we need to account for a variable amount of white-space, or we want to start thinking about multi-byte character encoding.

We can, and in the XML issue described by myself and Caron, I think the recommendation is very much to create editorial standards for signatures for file formats based on other baseline, structured data formats like XML, JSON, YAML, and so on.

And standards are well and good, but what if tooling could help us?

For JSON this is exactly what I have tried to do in JSONID.

What does this feature look like? And what does it get us? Let’s take a look.

Proposed this lightning talk for #NoTimeToWait9:

-------------------------------
Long-Term LTO: Stable LTO for "generations"?

What if we could get out of the #LTO-Generations update-race?
[...]
In this short talk, I'll present on how we might actually be able to get proper "Long-Term LTO" support for certain LTO-generations.

Declarative programming for Digital Preservationists @ NTTW8

Just released on the No Time to Wait (NTTW) YouTube channel is my presentation from NTTW8 in Karlsruhe, Germany. (Slides also available here).

The presentation follows up on my proposal for iPRES 2024 and allowed me to present parts of what was, in the end, a pretty significant paper (in terms of word count).

@BertrandCaron Looking forward!Ttime to pull the #nttw hashtag out of the drawer.

#ProRes follow-up for #iPRES2024.

Thanks @reto for the link to your #NTTW presentation. The #nttweffect is strong!

@BertrandCaron @r2gf I am also feeling the #FOMO for #NTTW8. It's especially sad because the workshop I'm co-hosting this year was inspired by #NTTW last year (AKA #nttwEffect). I'm planning to catch Friday sessions, but meetings are already sneaking up on me.

@r2gf
Same! I'm gonna miss entirely #NTTW because of #iPRES2024 preparation...
😭

@JennyMitcham Yes, I definitely agree it's the best version. It's time for me to reread the book, though. I doubt Brighton will live up to Lydia's hype, but we'll see. I'm not going to lie, it's hard for any conference to top the #NTTW energy

@ashley Seriously 😬 It seems like people really love complicated proprietary formats for recording video. On the bright side, maybe I'll have a contribution for the next #nttw ¯\_(ツ)_/¯

Second opportunity (not at my work) for AV Archivists. There is an Audiovisual Archivist position at UNESCO. https://careers.unesco.org/job/Paris-Audiovisual-Archivist/782714102/
The position is for a P2 and is based in #Paris. #AVpres #archives #digipres #nttw #nttw7

My #dp3 today was more of a #nntw7 three: 1) Trying to get a working group going to tackle #Wang disks (and word processing files), inspired by Leontien Talboom’s talk at nttw. 2) wrote local colleagues who were at #nttw to keep the exchange going, 3) asked our intern to present on her takeaways from #nttw at our next staff meeting

@mickylindlar @archivist_Liz
We started #NTTW with PREFORMA funding so focused on A/V by design, but after the end of the project archives started to sponsor themselves without any constraint so they do what they want there, #NTTW is "just" a place for you to meet ;-), so if you need to talk about more than A/V, it is welcomed. Organized by @MediaArea but driven by participants.

@mickylindlar I always encourage people who are even a little bit interested to attend #NTTW. I'm not an AV archivist or conservator, & there is a lot I don't understand. But I've still gained a lot from attending, even if it's just to learn what others are up to, to know who I can reach out to when I have AV (file) issues & to become more aware of my knowledge gaps. So I would encourage people to attend & also bring their own (preservation) issues. It's a pretty open and welcoming space #NTTW7

@mickylindlar I think #NTTW has included video game preservation and time-based art preservation at least since #NTTW4 in Budapest, so I would say #NTTW7 is continuing on that trajectory. But my impression is that the curriculum of students is changing and becoming more interdisciplinary, so I feel like I've spoken to several young professionals or grad students here who are really at the intersection of conservation, and AV, digital, and software preservation. It's exciting

@archivist_Liz
cool! I'm missing out on #NTTW7 again this year due to too much other stuff. What i heard/read though is that #NTTW has significantly expanded its horizont from just AV preservation to more complex object preservation topics. do you think that's acurate to say?

#ipres2023 Ricky Punzalan asking about what slowing down could mean in our work? How do we balance this with our feeling that there is no time to wait (to preserve obsolete media for example). #nttw #nttw7

@archivist_Liz when is it? haven't been to #nttw in a long time and prague & nttw is a trip that should be totally feasible on my own budget 🙂

@mickylindlar @JeromeM @ashley @digitensions I’m not sure who first used the expression, but there was a panel on the #nttw effect at #NTTW4. Finally did my homework 😅

@archivist_Liz didn't know there was such a thing as the #nttw effect! awesome. @ashley or @JeromeM - you know anything about this?

was the no time to wait effect ever defined? I guess I’ve always thought of it as good projects that came out of seeds or meeting people at #nttw. I’m thinking of putting it in an article. Halp?!?

Woo! No Time to Wait 7! November 8-10, 2023! In Prague! A favorite conference in one of my favorite cities! Uvidime se ve Praze! #nttw7 #nttw #digipres #avpres
