Structured DataAn Introduction to Semantic Web

“It is very hard for search engines to understand the structure and semantics of data embedded in an HTML page. To create these snippets, Google needs the help of hundreds of thousands of webmasters around the world, and by extension, content management systems like Drupal, Joomla!, and others. Specifically, Google is asking all of us to surface structured data to their crawlers by marking up our HTML with RDFa and Microformats.”

-Semanticweb.com, 2010

Magic Methods

<fieldset class="collapsible"><legend class="collapse-processed">

<a href="#">Click to Collapse</a></legend><div class="fieldset-wrapper" style="display: block;">

<p>This is how you collapse code. Now what?</p>

Rich Snippets & Microformats

Rich Snippets:



Micro Formats: Think of it as Metadata for your Element Tags.

Earliest forms of Micro Formats:- Vcards- RSS Feeds

“Reader” extrapolates descriptive info about the content in your tags


Rich Snippets & Microformats

Rich Snippets:



Several FrameworksRDFa, Microdata, Schema.org

RDFa example:

<span property="name" lang="en">John Smith</span>

Microdata example:

<span itemprop="name" lang="en">John Smith</span>


Drupal & RDFa

Drupal 7 core ships with some default RDF mappings for each built in content type like blog posts, articles, forums. You can change them or specify mappings for the new content types you might create on your site with the RDF module.

Resource Description Framework


Schema.org provides a collection of shared vocabularies webmasters can use to mark up their pages in ways that can be understood by the major search engines: Google, Microsoft, Yandex and Yahoo! You use the schema.org vocabulary, along with the microdata format, to add information to your HTML content. While the long term goal is to support a wider range of formats, the initial focus is on Microdata.
