Semantic-Linkbacks

Most modern WordPress themes support the older Microformats standard, which means the plugin should be able to get basic information from to enhance linkbacks. The plugin is most useful with webmention support(separate plugin) and sites/themes that support Microformats 2.

Webmention is a modern reimplementation of Pingback and is now a W3C Recommendation.

The IndieWeb community defines several types of feedback:

• Replies: http://indieweb.org/replies
• Reposts: http://indieweb.org/repost
• Likes: http://indieweb.org/likes
• Favorites: http://indieweb.org/favorite
• RSVPs: http://indieweb.org/rsvp
• Tagging: http://indieweb.org/tag
• Classic "Mentions": http://indieweb.org/mentions

See Extensions

The plugin will automatically enhance webmentions, trackbacks, and pingbacks with an avatar and additional context. It will also automatically add a facepile instead of individual comments, but this feature can either be turned off by an aware theme or under Discussion in your Settings.

Some emoji characters in webmentions you might receive, e.g. Facebook reactions from Bridgy, take more than two bytes to encode. (In technical terms, these Unicode characters are above the Basic Multilingual Plane.) To handle them, you need MySQL 5.5.3 or higher, and your database and tables need to use the utf8mb4 charset. Usually WordPress does this automatically, but not always. First, follow these instructions to switch your MySQL database to utf8mb4. Then, make sure DB_CHARSET and DB_COLLATE in your wp-config.php are either unset, set to the blank string, or set to these values: define('DB_CHARSET', 'utf8mb4'); define('DB_COLLATE', 'utf8mb4_general_ci');
