Extension:OpenGraphMeta

The OpenGraphMeta extension provides [ https://opengraphprotocol.org/ OpenGraph protocol] metadata for articles on the wiki for 3rd parties like Facebook to extract. The primary use for this extension is for any wiki that provides its users a button to "Like" pages on the wiki, especially if the wiki uses a custom default skin. As sometimes Facebook can extract undesirable parts from the page (known on some custom skins to potentially extract random images irrelevant to the content) providing this data gives Facebook clean data to display in likes, and cleans up the long title into a pair of clean site and page titles. A parser function which also exports what it is passed so you can use it easily in a  format can be used to set the image in the article which you prefer Facebook to use when displaying information about the page on your wiki (hint: This works very nicely when you incorporate it into an infobox template making the infobox image the preferred image for 3rd parties to use).

This extension can also be paired with which extracts description information from articles, when both are installed OpenGraphMeta will make use of the information Description2 extracts.

We need to provide the ability to maximize the amount of information available of the shared content so that it is more descriptive, while still in compliance with our policy.
