How different is CBOR compared to BSON? Both seem to be binary json-like representations.

Edit: BSON seems to contain more data types than JSON, and as such it is more complex, whereas CBOR doesn't add to JSON's existing structure.

That's not entirely true: with CBOR you can add custom data types through custom tags. A central registry of them is here:

https://www.iana.org/assignments/cbor-tags/cbor-tags.xhtml

This is, for example, used by IPLD (https://ipld.io) to express references between objects through native types (https://github.com/ipld/cid-cbor/).

I think parsing BSON is simpler than parsing JSON, BSON has additional types but the top level is always a document. Whereas the following are all valid JSON:

- `null`

- `"hello"`

- `[1,2,NaN]`

Additionally, BSON will just tell you what the type of a field is. JSON requires inferring it.

NaN is not part of JSON by any spec. Top level scalar values were disallowed by RFC 4627.
