Open Graph
Open Graph is a standardized protocol that FaceBook and other social media sites use to retrieve certain information such as images and descriptions from web pages.
The standard requires that URLs supplied are absolute. This means that SiteLinker needs to know the URL that will point to your project base on your server, in order to calculate the absolute URL for any images or other resources that are included with your project.
The Site Name refers to the name of your web site.
If the Warn if missing data box is checked, you will see a red alert at the bottom of your Section Editor if these values are not configured.
