DO NOT CHECK TYPES DURING VALIDATION
an Actor has an inbox and outbox. that's it.
an Activity has an actor. that's it.
a Collection has items or orderedItems. that's it.
etc
DON'T PANIC WHEN YOU SEE A TYPE YOU DON'T UNDERSTAND
say you understand tags of type Mention and Hashtag and Emoji. someone sends you a tag array with a raw Link. DON'T PANIC. the document is still valid. just filter out anything you don't understand, something like
UNDERSTOOD_TAG_TYPES = set("Mention", "Hashtag", "Emoji")
document = json.loads(...)
tags = document.get('tag', [])
tags = [
tag
for tag in tags
if tag['type'] in UNDERSTOOD_TAG_TYPES
]
# do whatever you need to now
const UNDERSTOOD_TAG_TYPES = new Set(["Mention", "Hashtag", "Emoji"])
let document = ...
tags = document.tag.filter(tag => tag.type in UNDERSTOOD_TAG_TYPES)
// do whatever you need to now
