Description:

This module provides a way of extracting, browsing and using RDF
metadata embedded in an SVG file.

The SVG spec itself does not provide any particular mechanisms for
handling metadata, but instead relies on embedded, namespaced RDF
sections, as per XML philosophy. Unfortunately, many SVG tools don't
support the concept of RDF metadata; indeed many don't support the
idea of embedded XML "islands" at all. Some will even ignore and drop
the RDF data entirely when encountered.

The motivation for this module is twofold. First, it provides a
mechanism for accessing this metadata from the SVG files. Second, it
provides a means of validating SVG files to detect if they have the
metadata.

The motivation for this script is primarily for the Open Clip Art
Library (http://www.openclipart.org/), as a way of filtering out
submissions that lack metadata from being included in the official
distributions. A secondary motivation is to serve as a testing tool
for SVG editors like Inkscape (http://www.inkscape.org/).
