W3C Fires Up the Semantic Web With GRRDL

(Last Updated On: 18. September 2007)

The Worldwide Web Consortium (W3C) issued another recommendation, and this time it concerns the Gleaning Resource Descriptions from Dialects of Languages (GRDDL) spec. GRDDL (pronounced "griddle") is purported to be yet another piece in the Semantic Web puzzle, which, when complete, would better enable data sharing over the Web.
The Semantic Web effort aims to take the human-readable part of the Web and make it understandable by machines. One of the potential uses of the Semantic Web is to better enable mashups of data, which might, for instance, be used to improve data exchange for applications such as social networking, online shopping and scientific publishing.
GRDDL's role in all of this is to take the various metadata expressions coded in XML in a document and enable them to be transformed (typically by XSLT) into a common parlance.
GRRDL uses namespaces and compatibility with the Resource Descriptive Framework (RDF) to link to algorithms for extracting the data in a document. GRDDL's task can be facilitated by the use of microformats, which are proposed descriptors for commonly used data item (such as "name," "company," etc.).
