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.

  1. You're a pain, Willison. Now I have to do that extract bit that you've done. :)

  2. I think once we put together an "official" PingBack specification we should make it clear that grabbing titles / descriptions is completely up to the blog that implements the system - that kind of thing shouldn't be required as the main focus of PingBack is "page A linked to page B". How that information is represented is up to the individual blogs. That said, the extract thing does end up looking pretty funky :)

  3. That is very neat indeed. Excellent stuff.

  4. Simon, could you show the code you use to extract page A's content ? I'm confused about how to do it (and match text around the link like you do). By the way, there's a bug in your comments count now, for example this entry is shown as having 0 comments, I wonder why :(

  5. The comment bug is probably just down to the comments code being a bit shakey :/ It's another issue that will be fixed when I move the blog. I'll blog the code for extracting links in a moment.
