I'm working on the top-level user interface for the worldoutline software, and have decided, for now at least, that blorkmarks will be a top level feature. I could leave them out in the first version, and introduce the concept as an upgrade a few months after the initial release. I might still do that. But I wanted to see if I could explain what they are to the relatively technical people who read this blog.
The core idea in the worldoutline is that you can put a marker on a headline that says this place begins a new space. Which allows you to use the outliner to organize all your spaces.
This way of organizing has lots of advantages. It lets you view a blog as a structure of documents you can edit. And it can allow you to fork off a new blog without increasing the complexity of the world you manage. This is something you're constantly fighting. A lot of spaces shouldn't overly complicate your life.
So how does a seam get expressed? How are these markers implemented? You could either come up with a web service that takes a name and tells you how to find your way to that place, or you could use a system that already does most of the job, DNS. This is one of my basic design principles. When possible use already-deployed and widely-supported protocols instead of inventing new ones. Lots of good reasons for this. That's why I used DNS. It scales, it's widely deployed, and I've always felt it was under-utilized, that there was a lot of power there lying dormant.
So here's how it works from a user standpoint. I put the cursor on a headline, and choose the Add Blorkmark command. It suggests a name, which I can override. Then it makes a call to a server which in turn calls Amazon's Route53, to register a cname, and associate it with the node you're pointing to. It takes 20 to 40 seconds for Amazon to do its work. And after that you have a way to get to this place. To the reader it looks as if it's a world unto itself, but in your view of the world, it's just a corner inside a bigger outline. A possibly much bigger outline, containing many such spaces.
