<p>
RDFa [RDFA-CORE] enables authors to publish structured information
that is both human- and machine-readable. Concepts that have
traditionally been difficult for machines to detect, like people,
places, events, music, movies, and recipes, are now easily marked up in
Web documents. While publishing this data is vital to the growth of
Linked Data, using the information to improve the collective utility of
the Web for humankind is the true goal. To accomplish this goal, it must
be simple for Web developers to extract and utilize structured
information from a Web document. This document details such a mechanism;
an RDFa Application Programming Interface (RDFa API) that allows simple
extraction and usage of structured information from a Web document.

</h4>
<div class="expand_description">
<p>Current web pages, written in HTML, contain significant inherent
structured data. When publishers can express this data more
completely, and when tools can read it, a new world of user
functionality becomes available, letting users transfer structured
data between applications and web sites. An event on a web page can
be directly imported into a user's desktop calendar. A license on a
document can be detected so that the user is informed of his rights
automatically. A photo's creator, camera setting information,
resolution, and topic can be published as easily as the original
photo itself, enabling structured search and sharing.</p>
<p>RDFa is a syntax for expressing RDF structured data in HTML.
This document provides use case scenarios for RDFa. An introduction
to implementing RDFa is provided in the RDFa Primer, while
the details of the syntax are explained in the RDFa Syntax (to be
published).</p>
