I'm looking for your opinions from the developers of the fediverse.

A common HTML web page can contain related links via the <link> tag. I would like to do the same for Activity Streams objects, for example:

{
  "@context": "https://www.w3.org/ns/activitystreams",
  "id": "https://writings.hongminhee.org/ap/2024/12/a-year-with-the-fediverse.json",
  "type": "Article",
  "name": "A year with the fediverse",
  "content": "2024 was truly a year where I was deeply immersed in the fediverse. …",
  "url": "https://writings.hongminhee.org/2024/12/a-year-with-the-fediverse/",
  "attachment": [
    {
      "type": "Link",
      "rel": "alternate",
      "hreflang": "ko",
      "href": "https://writings.hongminhee.org/2024/12/a-year-with-the-fediverse/index.ko-hang-kr.html",
      "mediaType": "text/html"
    },
    {
      "type": "Link",
      "rel": "alternate",
      "hreflang": "ja",
      "href": "https://writings.hongminhee.org/2024/12/a-year-with-the-fediverse/index.ja.html",
      "mediaType": "text/html"
    }
  ]
}

Do you think this makes sense, and would it be appropriate to put Link objects in the attachment?

@hongminhee I'm still new to ActivityStreams, but with how attachment is used for "extra data" it seems consistent.

Though, I did find that part a little confusing to learn since "attachment" makes me think of email, and in AS it's more than just files. I do wish there was a formal property specifically for "custom metadata" on an ActivityStream Object.

For this use-case, I would think the LanguageString type would be useful, but I guess mixing that with a URI type would make things messy.
