FEP Convergence (400e, 7888, 171b/Conversation Containers, 76ea)

Something like this:

{
  “@context”: “ActivityStreams 2.0 Terms”,
  “thr”: “https://purl.archive.org/socialweb/thread#”,
  “thread”: {
    “@id”: “thr:thread”,
    “@type”: “@id
  },
  “root”: {
    “@id”: “thr:root”,
    “@type”: “@id
  }
  “traits”: {
    “traits”: “inbox, outbox, conversation, amendable”
  }
}

This would let me know that it is a thread and that people can follow the context. I can then render it as a thread and potentially add a follow or subscribe button for the context.

You could also declare that it does not have an inbox and outbox, which saves me the trouble of checking myself.
