Like, this document, for instance: https://www.rfc-editor.org/rfc/rfc791
It's an official Internet Engineering Taskforce document that defines things like network protocols, etc. Often times there's really no specific individual(s) credited as the author(s), and even the official title can seem ambiguous.
The information on the title page is:
DARPA INTERNET PROGRAM
Defense Advanced Research Projects Agency
Information Processing Techniques Office
1400 Wilson Boulevard
Arlington, Virginia 22209
Information Sciences Institute
University of Southern California
4676 Admiralty Way
Marina del Rey, California 90291
So what's the official title and who get's the credit; DARPA, IPTO, ISI, USC, or IETF? I was going to do something like below, but I thought I should check with you guys.
