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.org/Article
2. http://schema.org/BlogPosting
3. http://schema.org/Blog

I got this code below example below, and I want to know what are the missing items or codes that could optimized a simple blog post that search engines can understand. I'd like to know all the rich snippets available for a blogpost.

<div id="blog_post" itemscope="" itemtype="http://schema.org/BlogPosting">
            <h2 itemprop="name headline">Post Title</h2>
            <div class="byline">
                Written by
                <span itemprop="author" itemscope="" itemtype="http://schema.org/Person">
                    <span itemprop="name">
                        <a href="https://" itemprop="url" rel="author">Author</a>
                    </span>
                </span>
                on
                <time datetime="2011-05-17T22:00" itemprop="datePublished">Tuesday May 17th 2013</time>
            </div>
            <div class="content" itemprop="articleBody">Content...</div>
</div>

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.

thanks for the concise explanation. Would mine sharing some of your codes, I am not sure how to do with the syntax especially the blog posting. Can I possible combine the three? – Hardbitten

@lordzden: What’s wrong with your example? Simply look at all available properties at schema.org/BlogPosting and decide which you can use for your content. -- If you have a typical blog (only publishing blog posts), you don’t need Article at all. – Frausto

I am using blogger, and I'd like to confirm that using the code, I have to put it on bloggers new post. right? – Hardbitten

It's taken me days to find the answer to my question, by looking at the first sentence in your answer. There's no concise documentation that states how it should be for a blog index page. But another question would be, inside the Blog schema, would each blog excerpt actually be a blogPosting object there? – Messick

@Lee: Yes, each BlogPosting (no matter it’s the full article or only a teaser) should be associated via blogPost to its Blog (similar to this example). – Frausto
