Das Atom Publishing Protocol

ist ein standardisiertes Protokoll
zum Übertragen von Inhalten
auf (und von) Websites.

I have often stated that there are 7

of RSS. (...)
I would like to publicly apologize for
my previous misstatements. There are
not 7 different and incompatible
versions of RSS; there are 9.
