One thing is very clear from the #ipres2026 hallway-track:

A lot of small preservation-institutions could really use some volunteer IT-geeks/Architects, to help them get the IT/storage part of preservation figured out.

One (hypothetical?) example could be a camera which encrypt the raw images with the camera's serial number, or if the camera vendors own software application program pulls the camera's calibration data from the company's web server.

So my advice (= from the volunteer digital archivist at datamuseum.dk)

Focus on the "self-contained" aspect: Does your digital artifact actually contain all the information required ?

As somebody who is coming from the opposite side, (computing history) where most of our artifacts arrive in proprietary formats:

Given enough nerds, all self-contained data-formats where sufficient artifacts are available, can be reverse engineered.

The "self-contained" is the important part, any format which needs input (encryption or license keys) from external sources is deeply problematic, and must be converted while that information is available.
