In this presentation I provide a gentle introduction to successful open web protocols such as OpenID, OAuth, Atompub and OpenSocial in terms of what they provide as well as how they can be useful to developers. Presented at the inaugural MSCOSCON 2009 in Malaysia. Note: This presentation draws from a lot of existing content online and I have attempted to ensure that the sources have copyright that allowed reuse as well as all sources have been duly attributed. If there is any attribution missing or misuse of content please do contact me and I will rectify it.

Not about technologies "...However, if we define the Open Web in terms of these technologies , then we risk losing sight of what makes the web special and being able to have the intellectual nimbleness to evolve the infrastructure of the web." -Brad Neuberg, Dojo, Google Gears developer http://www.flickr.com/photos/uhop/2250235637 http://codinginparadise.org/weblog/2008/04/whats-open-web-and-why-is-it-important.html
