Blog Posts Optimized by Schema

Question

I am quite new to these approach in optimizing my HTML with Rich Snippets. I am not sure what is the differences of each of the list items below:

1. http://schema

Answer 1

http://schema.org/Blog can be used on the front page, where you typically find a list of several blog posts (and maybe also for blog-wide things on every page, like the blog name).

http://schema.org/BlogPosting represents a single blog post.

http://schema.org/Article is just more general than http://schema.org/BlogPosting (every BlogPosting is a Article, but not every Article is a BlogPosting). If you have a typical blog, you want to use http://schema.org/BlogPosting.
