Semantically marking up a "checklist" or process

Hi everyone, 

I run a startup called http://tallyfy.com

We've just been enrolled into StartupChile, and aim to launch within a few months using their help. Our homepage looks something like this:
https://dl.dropboxusercontent.com/u/14563542/tallyfy.png

What we do is allow anyone to embed knowledge as steps in a checklist or a process. Examples might be:
How to bake a carrot cake
How to change a bicycle tyre
What to pack if you're visiting the Amazon rainforest
My bucket list

The clearest and most obvious point to make here is that these checklists, when marked up via schema.org would be excellent ways to present answers to questions without people going through many pages on search engines.

So I wanted to propose a schema for marking up a checklist (or a process). If there is one already - could someone point me to it?

If we could understand that this is a "set of steps for doing something" - I think that would be very valuable, not just to search but for people looking for knowledge which is actionable, not just web pages. In other words, an actual set of steps marked up is more valuable than a block of content (usually using <ol> or <ul> HTML) which blends into a web page.

We intend to do a lot more - you can measure how many people did a checklist, how long it took on average, reviews, etc. so perhaps those could incorporate into this schema.

thanks
Amit
