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.
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.

GRDDL is a mechanism for Gleaning Resource Descriptions from Dialects of Languages. It is a technique for obtaining RDF data from XML documents and in particular XHTML pages. Authors may explicitly associate documents with transformation algorithms, typically represented in XSLT, using a link element in the head of the document. Alternatively, the information needed to obtain the transformation may be held in an associated metadata profile document or namespace document. Clients reading the document can follow links across the Web using techniques described in the GRDDL specification to discover the appropriate transformations. This document uses a number of examples from the GRDDL Use Cases document to illustrate, in detail, the techniques GRDDL provides for associating documents with appropriate instructions for extracting any embedded data.
