Is there an #opensource backed standard for annotating others’ webpages? I’m thinking specifically being able to tag others’ sites with #IndieWeb h-cards (eg. Adding machine readable event tags to pages like this: https://www.ewanbleach.com/events) or something more fancy, like letting me attach (#ipvm runnable?) WASM to that page that will extract an iCal file. I want to make microformats and standard metadata more available without everyone having to get on board.
