Facebook’s Favorite Metadata

[Facebook’s guide to sharing][1] details some meta tags to make that sharing work better:

In order to make sure that the preview is always correctly populated, you should add the tags shown below to your html. An example news story could have the following:

> As shown, title contains the preview title, description contains the preview summary and image_src contains the preview image. Please make sure that none of the content fields contain any html markup because it will be stripped out. For consistency’s sake, please use the 
> <meta />
> tag to provide text data for the preview, and the 
> <link />
> tag for any source urls.
> The title and summary tags are the minimum requirements for any preview, so make sure to include these two.
