E2AF
E2AF is an acronym for Extended Enterprise Architecture Framework.
E2AF was published in 2006 by the Institute For Enterprise Architecture Developments (IFEAD), whose president was Jaap Schekkerman. The official website of IFEAD is down, but you can access its archive version from this external link.
Considering that latest version of E2AF is from 2006 and that IFEAD web is down, I can conclude that this framework is no longer maintained. Anyway, I have seen it still quoted in some sources.
The E2AF Essentials Guide can be still viewed from this external link.
E2AF is mentioned in CISM Review Manual 15th Edition.
