The concept of Widon't is explained in Shaun Inman's Blog. Here's a short summary and the implementation as TYPO3 extension.

TYPO3 6.0, scheduled for October 2012, will introduce quite some changes under its hood, especially for developers. All PHP classes were migrated to namespaces and by the way most of the classes were renamed and moved to new folders.

The content elements shipped with TYPO3 like "Text & Images" or "File Links" are defined in the so called TCA (Table Configuration Array). By manipulating this array you can modify existing content elements or even create completely new ones - without TemplaVoilà.

Together with og:title and og:image, og:url and og:type make up the four mandatory fields of the Open Graph Protocol. In this article I'll introduce the two latter to you. Once again the implementation in TYPO3 is lean and easy.

Recently I've shown how to use the og:image tag to get images from TYPO3 into the facebook posting preview. Today I want to show og:title and og:site_name and their TYPO3 implementations.
