<p>GRDDL is a mechanism for Gleaning Resource
Descriptions from Dialects of Languages. This
GRDDL specification introduces markup based on existing standards for
declaring that an XML document includes data compatible with the
Resource Description Framework (RDF) and for linking to algorithms
(typically represented in XSLT), for extracting this data from the
document.</p>
<p>The markup includes a namespace-qualified attribute for use
in general-purpose XML documents and a profile-qualified
link relationship for use in valid XHTML documents. The GRDDL
mechanism also allows an XML namespace document
(or XHTML profile document) to declare that every document associated
with that namespace (or profile) includes gleanable data and for
linking to an algorithm for gleaning the data.</p>

</h4>
<div class="expand_description">
<p>Both XLink [XLink] and RDF [RDF] provide a way of asserting relations between
resources. RDF is primarily for describing resources and their
relations, while XLink is primarily for specifying and traversing
hyperlinks. However, the overlap between the two is sufficient that
a mapping from XLink links to statements in an RDF model can be
defined. Such a mapping allows XLink elements to be harvested as a
source of RDF statements. XLink links (hereafter, "links") thus
provide an alternate syntax for RDF information that may be useful
in some situations.</p>
<p>This Note specifies such a mapping, so that links can be
harvested and RDF statements generated. The purpose of this
harvesting is to create RDF models that, in some sense, represent
the <em>intent</em> of the XML document. The purpose is
<em>not</em> to represent the XLink structure in enough detail that
a set of links could be round-tripped through an RDF model.</p>
