Request For Comment (RFC) is an alternative to the Technology Adoption Process allowing an OMG member to request OMG adoption of an uncontentious specification without requiring a Request for Proposals to be issued.

A Request for Comments (RFC) is a formal document drafted by the Internet Engineering Task Force (IETF) that describes the specifications for a particular technology. When an RFC is ratified, it becomes a formal standards document. RFCs were first used during the creation of the ARPANET protocols that came to establish what became today's Internet. They continue to be issued on an ongoing basis as the technology underlying the Internet evolves.
