RFC 7483, "JSON Responses for the Registration Data Access Protocol (RDAP)", March 2015Source of RFC: weirds (app)
Errata ID: 6158
Publication Format(s) : TEXT
Reported By: Scott Hollenbeck

Section 10.2.3 says:
Description: The object instance was transferred from one registrant to another.
It should say:
Description: The object instance was transferred from one registrar to another.
I believe the corrected text is what was intended for this particular registry value, and is what is being implemented by operators today. Registrant-to-registrant transfers are also possible, but they're not performed using EPP and are not logged as an event action. The text in the RFC should be changed and the description of the action in the IANA registry should also be changed.
