Transfer Methods. This is at the core of REST and ROA and is the foundation of Web-Oriented Architecture. You can read Roy Fielding's chapter on REST (he conceived of the approach originally) or you can just follow the simple guidelines here. At other times, protocols like BitTorrent can be used if the requirements warrant it, but these are exceptional scenarios that I will cover at some point in the future.

Ne pas citer XMPP dans les "Transfer Methods" quelque jours après l'annonce de Google Wave, et surtout le mettre dans le schéma au niveau des Microformats fait perdre toute crédibilité à l'article.
