Gleaning Resource Descriptions from Dialects of Languages (commonly abbreviated GRDDL), is a programming language for translating one form of data (typically presented as an unstructured document on the web) into a better structured, more semantic representation such as OWL or RDF.

On top of GRDDL, it is possible to build translation engines, data mining tools and other similar services.

XHTML & Transformations

A document specifies associated transformations, using one of a number of methods.

For instance, an XHTML document may contain the following markup:

   <head profile="">

   <link rel="transformation" href="grokXFN.xsl" />

Document consumers are informed that there are GRDDL transformations available in this page, by including the following in the PROFILE attribute of the HEAD element:

The available transformations are revealed through one or more LINK elements:

   <link rel="transformation" href="grokXFN.xsl" />
