Today's done #dp3 are
1. #iPRES2025 Attendee Experience Committee meeting. We're making progress! (Let me know if you're keen to help)
2. Planned a brainstorming session for a proposal for a #iPRES2025 panel discussion on #DigiPres challenges and opportunities in the Asia-Pacific and Australasia region, with a focus on pragmatic digital preservation.
3. Compare two spreadsheets using Excel Power Query. Hoping to build a repeatable workflow.

Thought some of the other #digipres nerds might be amused by this sign as well.

If you're the person who just won the eBay auction for seven "1985 Antic Software Atari ST Game Disks" for $107.50, please get in touch. I want to make sure the monochrome version of "Mom and Me" gets archived.

For those that missed it, last year I published a dive into the files and formats of the Titan A.E. demo. There's this and more available on our blog for those interested in #gamedev and #digipres, with more on the way!

niche question time! i'm trying to figure out what PREMIS event type would express "destroyed original carrier." If you use PREMIS and record this info, what value do you use? https://id.loc.gov/vocabulary/preservation/eventType.html #preservation #digipres

anyone know of articles/blogs and/or has personal experience with:

let me know!

Exciting news! We're thrilled to welcome the Council of Prairie and Pacific University Libraries (COPPUL) to the DPC as our newest Associate Member! Through their Digital Stewardship Network, COPPUL has shown incredible dedication to digital preservation across Manitoba, Saskatchewan, Alberta and British Columbia.

48 vs 96 kHz for audio preservation?

I would still opt for 48kHz/24bit as perfectly sufficient.

In case of noisy/low-fi sources (Shellack, wax-cylinders, etc) one may choose 96kHz to have headroom for restoration.

Other than that, to capture regular-quality audio: Anyone got a good reason to go >48kHz?

Mentioned just now in one of the #BDCAM25 Lightning talks: the @dpc_chat’s Rapid Assessment Model (#DPCRAM), a #DigitalPreservation maturity modelling tool that has been designed to enable rapid benchmarking of an organization’s #DigiPres capability & facilitate continuous improvement over time https://www.dpconline.org/digipres/implement-digipres/dpc-ram

#BDCAM25 Really interesting presentation from @criticalsenses & colleagues at the Science Museum Group about the #DigitalPreservation of the Absolute Unit meme, as well as the first steps in the #DigiPres programme of the SGM (DigiPres policy & guidelines, Digital Asset Register, Digital Formats Complexity Scale etc.)

For those wanting to learn more about #PREMIS, the #DigiPres metadata dictionary & schema mentioned in the #BDCAM25 session on the #DigitalPreservation of complex (museum) digital objects
https://www.loc.gov/standards/premis/

Starting day 2 of #BDCAM25 with a session on collecting & #DigitalPreservation of complex objects. What are "complex objects"? Very good question, with the usual #DigiPres answer "It depends". You might want to have a look at this thread for stronger opinions https://digipres.club/@BertrandCaron/114002134938577661

'Monitoring Carbon Emissions at Home'.

Mini #digipres thread about invalid #PDF files, #JHOVE and PDF-HUL-114

( @BertrandCaron is leaving the old house, it's time to step up!)

At the beginning, there was a PDF 1.7 file donated to the #BnF and declared invalid by JHOVE 1.32.0. I start my investigation to find out if this is serious and if I'm going to repair the file (this is the way @mickylindlar told us to go)

The Xiph.Org Foundation has for many years hosted a collection of #lossless audio and video test clips to support the compression research community.

Unfortunately, that server may be going away soon. I'm looking at various options to keep the data online, but I wondered if it would be appropriate to upload a copy to @internetarchive The current collection is around 20 TB.

If so, what would be a good format? For clips originating in yuv, ffv1 or lossless vp9 compression is probably a good choice. (Uncompressed is usually best for benchmarking, but people can extract on their own.) Downloading multi-GB files is easier than it used to be. However, the highest quality for some clips are directories of png, tiff, or exr files. Not sure what to do with those. Tar them up? Will archive.org fall over if I upload 20,000 files as part of the same object?
