Structured Blogging for Learning Objects?

You probably know about Structured Blogging, a WordPress plugin for easily creating human and machine readable posts of specific kinds. (This is a screenshot of the authoring interface.) You can see the results under my book reviews tag. What I want to know is this – why haven’t we created a WordPress plugin for creating learning materials and presenting these as human and machine readable resources? Better yet, why stop with a simple authoring system like WordPress+plugin, why don’t we put something like AFLAX on the front end?

What would the authoring interface look like? What information should we capture? Drop your thoughts in the comments section and we’ll get something hacked up.
