## 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
|
|
|
|
```python
|
|
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
|
|
```
|
|
|
|
```javascript
|
|
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
|
|
``` |
