Use blocks, and, optionally, ”short-form” post types to easily ”IndieWebify” your WordPress site.
IndieBlocks registers several blocks (Bookmark, Like, Reply, and Repost, as well as the older Context block) that take a URL and output corresponding microformatted HTML.
In combination with a microformats-compatible theme, these help ensure microformats clients are able to determine a post’s type.
It also comes with ”short-form” (Note and Like) custom post types, and a (somewhat experimental) option to add microformats to (all!) block-based themes.
These microformats, in combination with the Webmention protocol, allow for rich cross-site conversations. IndieBlocks comes with its own Webmention implementation, but a separate plugin can be used, too.
IndieBlocks also registers several ”theme” blocks (Facepile, Location, Syndication, and Link Preview), to be used in ”block theme” templates.
