The W3C Social Web Working Group is calling for review of Webmention, which is now a Proposed Recommendation. Webmention provides a mechanism for a webpage to notify another webpage when it mentions its URL, and when the content around the mention changes or is deleted. From the receiver’s perspective, it’s a way to request notifications when other sites mention it. This mechanism is a core building block for a decentralized (social) Web, because it allows sites to automatically learn about connected content, without any prior setup or agreement. For users, an immediate benefit is cross-site comments. Comments on the PR are welcome until 30 November.
