Yes, every document has two non-optional attributes: - _key - ex: _key: "1234" - _id - ex: _id: "myCollection/1234"
Both _id and _key are strings, and the value of _id is the collection name plus the _key, concatenated with a forward-slash. All document collections have non-alterable indexes that cover these attributes. All edge collections also have required properties: - _from - ex: from: "myCollection/123" - _to - ex: _to: "myCollection/abc" All edge collections have non-alterable indexes that cover these attributes as well.
