W3C Invites Implementations of Linked Data Notifications (LDN)

The W3C Social Web Working Group is calling for implementations of Linked Data Notifications (LDN), which is now a Candidate Recommendation. LDN describes how servers (receivers) can have messages pushed to them by applications (senders), as well as how other applications (consumers) may retrieve those messages for use, for example in a user interface, or an automated process. Any resource (like a blog post, or a user profile) can advertise a receiving endpoint (Inbox) for the messages targeted to that resource. The messages themselves are expressed in RDF, and can contain any data. Implementations can be any or all of senders, recievers or consumers. Existing Linked Data Platform implementations are already LDN conformant receivers – an LDN Inbox is just an LDP Container – so we particularly encourage testing and reports from previous implementors of LDP.
