Fingerprints

Fingerprints of Node API objects always start with a string designating the type of the object. Version of a fingerprint defines a concrete revision of the fingerprint structure if it was changed in backward-incompatible way. The fingerprint version (also known as "signature version") must be returned from Node API call together with the signature.
