I only knew of Dublin Core as it relates to image metadata. I was told it was popular among photo-journalists (it has tags: publisher, keyword, creator). The more nerdy EXIF metadata is what the camera often provides and tells you about how the image was taken (f-stop, shutter speed), not who or what.

Not "who" or "what" but "where" can also be saved in the EXIF data.

  Now if there were some universal standard for embedding alt-texts into a picture that would also survive right-click "copy image" and paste-uploading... not just for social media (where you'll get blasted for forgetting one even just one time) but also for websites and newspapers where the image description has to be edited manually in a CMS and is, again, not attached to the picture itself...

    There is. The problem is that automatically attached alt-text isn't particularly useful. You don't know what the intention is of an image. Is it of a banana? A specific banana? The sticker on the banana? https://shkspr.mobi/blog/2023/07/should-you-embed-alt-text-inside-image-metadata/ https://shkspr.mobi/blog/2023/07/should-you-embed-alt-text-i... And, no, this isn't something which AI can help with. https://tink.uk/thoughts-on-screen-readers-and-image-recognition/ https://tink.uk/thoughts-on-screen-readers-and-image-recogni...

      Fantastic articles, thank you. I work with alt text a lot. I used a hinted LLM prompt for the first pass, and then I edit if needs be. Sometimes it misses obvious details, other times it sees things (most) human eyes would never see. Like all tools, just have to be careful how you use it.

      My use case is "someone shares a dank meme on twitter, i save it to share it on bsky", and every time I have to copy the alt-text myself.

  Photographer entry can be done in camera-specific section, it's recognized by a lot of parsers

I think most of the news media has long switched to IPTC meta data.

  You're right and I am wondering now if I was confusing IPTC with Dublin Core. (Oops.)
