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 Document Object Model Application Programming Interface
(RDFa DOM API) that allows simple extraction and usage of structured
information from a Web document.
