More Vellum

Vellum 1.0a4 is out, and features comment support via a new Comments plugin and an Audience generic object type that abstracts the concept of “responses to your post” and is also used for Pingback support. Different response types within the same interface is a very neat idea, as Sam Ruby has demonstrated with his integrated comments, referral tracking, Pingbacks and TrackBacks. Stuart also suggests auto-discovery of You-Know-Me information from the URL of your weblog, presumably by another link element. This is a great idea, but I have reservations about the performance trade off as unauthenticated comment systems will have to retrieve the poster’s home page in the background every time they make a post.

Pingback implemented

I’ve implemented PingBack on my blog. PingBack is a system for tracking who is linking to your blog in a controlled way, based on a post by Stuart a few months ago. The idea is that when you link to a PingBack enabled blog you (or your blogging tool) should send an XML-RPC “ping” to that blog’s PingBack server telling it where you have linked to and where you linked from. The PingBack server can then grab your page, check that the link is there and extract a title and short description from the blog. The system is an alternative to (and was inspired by) MoveableType’s TrackBack feature. Stuart and I are actively developing the idea and will be releasing code and documentation to help other people experiment with the system in the near future.

MovableType have released version 2.21, which finally introduces support for mySQL and also comes with an intriguing new feature called TrackBack. I’m stil trying to figure out exactly what TrackBack is.. so far I’ve figured out that it invovles embedding RDF information directly in to your blog which can then be combined with a “ping” to other blogs to inform them that you have linked to them, and give them additional information about your blog for display on a special TrackBack section for each of their blog entries. Scott Andrew has already implemented it and many other MovableType blogs are setting it up as well. TrackBack has its own blog, which has an interesting entry hinting that TrackBack could soon become part of a system for distributed taxonomies (a problem that XFML is also looking to solve).
