Provide some additional Open Graph meta tag in your Plone site, so share items on Facebook will be simpler
Project description
Add new meta tags to you Plone site, for better controlling how your items are shared on Facebook.
Introduction
Are you commonly sharing contents from your Plone site or a site page to a Facebook account?
When you use the nice Facebook sharing interface, you have a simple way to customize additional data for the item that will be published (mainly: choose a proper image from the remote page). However when trying to do this automatically (e.g: you are publishing the link in a Twitter account that also feed a Facebook page) Facebook is choosing an image for you… and often this is not the image you want.
How can you solve this? In general you can provide some additional meta tag information using Open Graph standard, customizing many aspect of the way of sharing contents on Facebook.
