balintmwould an anchor with rel=alternate be semantically correct in a scenario where a particular page's content is represented in a video elsewhere? eg. linking to the recording of a talk based on or incorporating the same content in some form
balintmsorry i was unclear — my example is more like a blog post with that has <a href="https://youtube.com/…" rel="alternate">, and the video is a talk based on that very post
[tantek]Problem with YouTube or any silo versions of talks or anything is that you have no control over how much they will (further) enshittify their permalinks
balintmtrue. though in practice it's probably extremely unlikely that existing youtube URLs break (given both yt and the video in question exist of course)
[tantek]It has nothing to do with URLs breaking. It has to do with the what's at the URL just getting crappier and crappier til it's overwhelmed with login prompts, native app downloads, ads surrounding what little actual content is there
balintmyeah i get that. for context this question came up because i'm about to do a talk that partially covers the contents of one of my articles. it's at a conference and i will not have the rights to the recording, nor the rights to reupload it — but it will be available on the conference's channel. prob just a regular link, just musing on whether rel=alternate or any of the syndication markup formats would apply in this case
[tantek]I'm not sure rel=alternate makes sense for linking to a resource you don't control / have rights to or at least have a good faith ability to change via feedback.
[tantek]One example exception is linking to voluntary translations of a post. E.g. I've had blog posts sometimes translated by independent volunteers on their own blogs, and I feel ok linking to those with rel=alternate lang=de (for example) because there is a good faith sense of mutual feedback/respect ec.
[KevinMarks]I would suggest downloading the talk with a YT downloader so you have a relatively clean backup in case the conference organisation vanishes
