Keys To Organize Your Website Semantically Part One
Have you heard of " Semantic Web " or " Web 3.0 "?
This new concept refers to the ability of software to interpret data in the most human way possible, going beyond the simple input and output of data and processing the information semantically.
This occurs through two mechanisms: the inclusion of labels or semantic metadata and hierarchically structuring the content.
The Content
The inclusion of semantic metadata serves to be interpreted by browsers and search engines, benefiting searches and access to information for all network users.
For the identification and cataloging of information, we have several mechanisms. The best known are RDF, MICROFORMATS, and MICRODATA:
RDF (Resource Definition Framework)
It is a set of extensions that provides a simple description of the content of the Web. Example:
- <span property = »v: title» > TITLE OF THE ARTICLE OR PAGE </span>
- <span property = »v: url» > www.urldelaweb.es </span>
Microformats Are Portions of HTML (or XHTML) Code
They allow you to structure information by taking advantage of some HTML tags' "id" or "class" attributes.
HTML 5 Microdata
Also known as rich snippets. Some examples:
- <span itemprop = »title» > Title of the article or page </span>
- <span itemprop = »url» > www.urldelaweb.es </span>
- <span itemprop = »description» > Description </span>
- <span itemprop = » Keywords » > Tags or keywords </span>
- <span itemprop = »creator» > Content author </span>
The three types try to solve the same problem in a different way, the most comfortable, simple and valued mechanism by Google being microdata or enriched fragments .
These add an additional meaning to the contents and group all the semantic labels, differentiating them from those used for the visual function. They also use a vocabulary such as schema.org .
For testing them, Google offers us a very useful tool: http://www.google.com/webmasters/tools/richsnippets.
