                        <p>Selectors, which are widely used in CSS, are patterns that match
against elements in a tree structure [SELECT][CSS21]. The Selectors API
specification defines methods for retrieving <code>Element</code>
nodes from the <abbr>DOM</abbr> by
matching against a group of selectors. It is often desirable to
perform DOM operations on a specific set of elements in a document.
These methods simplify the process of acquiring specific elements,
especially compared with the more verbose techniques defined and
used in the past.</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.
