How do I add a semantic definition in an HTML tag to a JPEG, or MP4, or WAV, or any non HTML format? HTML tags fix HTML, not other formats.

What would the difference in semantic notation between an unstructured "ai.txt" and the "alt" attribute actually be? If you want the tags to be served with the context outside of HTML, you can always use HTML header attributes.

JPEG has EXIF, MP3 has ID3 tags, MP4 has ilst, MKV has Tags, etc. We don't need xkcd/927 for these other formats that already have standard metadata mechanisms.

>>burnte+(OP)
If you're describing an object on the page, like an image or video, you want a label element linked to it by id and likely an aria-label attribute on the object. (screen readers and such will look for this in particular). For an image you want an alt text attribute as a description too.

Yeah, and if you make it that complex to extract consent you won't get any. Think one step ahead maybe. One switch, one thing to parse.

Robots.txt is where you tell crawlers (AI or otherwise) what should and shouldn't be read on your site.

Metadata like in tags, HTML meta tags, etc. is where you describe the content so meaning can be extracted from it by machines and automated processing.

1. OP said “what it is about, when was it published, the author, etc.” That’s what these mechanisms already cover. Consent is an interesting possibility that I’ll admit something like ai.txt might be better for, but my post was largely focused on the OP.

2. These are all complex formats. If you want to ingest and process them then you already have to build all the hard parts. Getting the metadata out is dead simple compared to parsing, decoding, and then processing an image, for example.
