This module adds [Open Graph Protocol](https://ogp.me) metadata to URLs sent inside a MUC. |
|
|
4 |
|
|
|
5 |
With mod_ogp enabled, when a user sends a URL in a MUC (where the message has its `id` equal to its `origin-id`), the module calls the URL and parses the result for `<meta>` html tags that have any `og:...` properties. |
|
|

If it finds any, it sends a [XEP-0422 fastening](https://xmpp.org/extensions/xep-0422.html) applied to the original message that looks like: |

``` |

<message id="example" from="chatroom@chatservice.example" to="chatroom@chatservice.example"> |
|
|

<apply-to xmlns="urn:xmpp:fasten:0" id="origin-id-X"> |

<meta xmlns="http://www.w3.org/1999/xhtml" property="og:title" content="The Rock"/> |

<meta xmlns="http://www.w3.org/1999/xhtml" property="og:url" content="https://www.imdb.com/title/tt0117500/"/> |

The module is intentionally simple in the sense that it is basically a transport for https://ogp.me/ |
