File formats as Emoji: 0xffae

File Formats As Emoji (0xFFAE or 0xffae) might be my most random file format hack yet. Indeed, it is a random page generator! But it generates random pages of file formats represented as Emoji.

The idea came in 2016 with radare releasing a new version that supported an emoji hexdump. I wondered whether I could do something fun combining file formats and the radare output to create a web-page.

Along came a spare moment one weekend, some pyscript, and bit of sqlite, et voilà. File Formats as Emoji (0xFFAE) was made a reality.

Tyler's Halloween Matryoshka Dolls represent the internal complexities of container file formats. The dolls here have formats attached to them representing different ways they might be nested, with ZIP and OLE2 being the primary containers that can be handled in DROID and Siegfried at present.

A year in file formats 2024

A great write up from Francesca at TNA about the past year for PRONOM via Georgia at the OPF.

It’s great to see the continuing work including vital translation of guides into other languages. Francesca includes a couple of shout outs to some pieces I have contributed in my spare time this year; including a collaborative workshop with Francesca, David, and Tyler at iPRES2024.

PRONOM’s dustiest records

Tyler’s recent blog post for the PRONOM Hack-a-thon Week 2024 (my previous for this week), brought up an interesting point about two of PRONOM’s oldest outline records, Real Video Clip (fmt/204) and Real Video (x-fmt/277). How did they end up in PRONOM?

NB. because of the complexity of this post, it may be easier to read in original blog form, than on Mastodon here: https://exponentialdecay.co.uk/blog/pronoms-dustiest-records/

Tyler suggests:

I assume PRONOM originally added these based on MIME types available.

I thought I knew the answer, but it prompted a forensic look at the records to see if what I thought I knew aligned with reality!

Making DROID work with Wikidata

Wikidata is a good service, Wikibase (on which Wikidata is built) is a better platform.

I have spoken before about its potential to be added into the file-format registry ecosystem in a federated model.

If we are to use it as a registry that can perhaps complement the pipelines going into PRONOM, e.g. in vendor’s digital preservation platforms such as the Rosetta Format Library, a Wikidata should be able to output different serializations of signature file for tools such as Siegfried, DROID or FIDO.

And what about DROID?
