I've been in the middle of two separate initiatives with MeTal as of late. First is some internal cleanup, where many things that were broken out into their own modules are being rolled back into the model schema where they belong. (Bad planning on my part.) The other is progressively adding more details to the export dumps I create from Movable Type, as a way to figure out what features to add to MTL to support a blog migration.
The long-term plan is to migrate one of my other blogs completely to MTL, then use that as a testbed on top of which to complete the feature set, and as a place to develop at least one of the templates that'll be packaged with the program. The template you're seeing now is another one -- you'll be seeing more rolled into it over time as the planned feature set expands.
I also have at least one possible other alpha-tester in the works, but in order for that to work, I'll need to devise some kind of importer for WordPress. That was an inevitability, I guess. I hate the idea of having to deal with WP's XML-based export format (yecch), but the vast majority of people running a blog use WP, so there's no way to duck around that. Good thing Python has a standard library for dealing with XML, right?
