Friendica has got a functionality like Twitter has got as well: Resharing an item with an additional quote to it. I now want to build this in AP as well. I thought of using the “attachment” value for this:
[attachment] => Array (  => Array ( [type] => Note [id] => https://pleroma.soykaf.com/objects/df9c8bec-ba84-41d8-a955-3fbe0d88ed89 ) )
I’m not totally sure if this is 100% AP conform, but I don’t know a better solution. What do you think?
