http://www.w3.org/ -- 11 September 2007 -- Today, the World Wide Web  
Consortium completed an important link between Semantic Web and  
microformats communities. With "Gleaning Resource Descriptions from  
Dialects of Languages", or GRDDL (pronounced "griddle"), software can  
automatically extract information from structured Web pages to make  
it part of the Semantic Web. Those accustomed to expressing  
structured data with microformats in XHTML can thus increase the  
value of their existing data by porting it to the Semantic Web, at  
very low cost.

"Sometimes one line of code can make a world of difference," said Tim  
Berners-Lee, W3C Director. "Just as stylesheets make Web pages more  
readable to people, GRDDL makes Web pages, microformat tags, XML  
documents, and data more readable to Semantic Web applications,  
opening more data to new possibilities and creative reuse."

Getting Data into and out of the Web; how is it happening today?

One aspect of recent developments some people call "Web 2.0" involves  
applications based on combining — in "mashups" — various types of  
data that are spread all around on the Web. A number of active  
communities innovating on the Web share the goal of sharing data such  
as calendar information, contact information, and geopositioning  
information. These communities have developed diverse social  
practices and technologies that satisfy their particular needs. For  
instance, search engines have had great success using statistical  
methods while people who share photos have found it useful to tag  
their photos manually with short text labels. Much of this work can  
be captured via "microformats". Microformats refer to sets of simple,  
open data formats built upon existing and widely adopted standards,  
including HTML, CSS and XML.

This wave of activity has direct connections to the essence of the  
Semantic Web. The Semantic Web-based communities have pursued ways to  
improve the quality and availability of data on the Web, making it  
possible for more intensive data-integration and more diverse  
applications that can scale to the size of the Web and allow even  
more powerful mash-ups. The Web-based set of standards that supports  
this work is known as the Semantic Web stack. The foundations of the  
Semantic Web stack meet the requirements for formality of some  
applications such as managing bank statements, or combining volumes  
of medical data.

Each approach to "getting your data out there" has its place. But why  
limit yourself to just one approach if you can benefit, at low cost,  
from more than one? As microformats users consider more uses that  
require data modelling, or validation, how can they take advantage of  
their existing data in more formal applications?

A Bridge from Flexible Web Applications to the Semantic Web

GRDDL is the bridge for turning data expressed in an XML format (such  
as XHTML) into Semantic Web data. With GRDDL, authors transform the  
data they wish to share into a format that can be used and  
transformed again for more rigorous applications.

GRDDL Use Cases provides insight into why this is useful through a  
number of real-world scenarios, including scheduling a meeting,  
comparing information from various retailers before making a  
purchase, and extracting information from wikis to facilitate e-
learning. Once data is part of the Semantic Web, it can be merged  
with other data (for example, from a relational database, similarly  
exposed to the Semantic Web) for queries, inferences, and conversion  
to other formats.

The Working Group has reported on implementation experience, and W3C  
Members have come forward with commitments to implement GRDDL on  
sites and in products.

GRDDL Test Cases is also published today, which describes and  
includes test cases for software agents hoping to support GRDDL. The  
Working Group has produced a GRDDL service that allows users to input  
a GRDDL'd file and extract the important data.

These testimonials are in support of W3C issuance of GRDDL as a W3C  
Recommendation.

    The Dublin Core Metadata Initiative congratulates the W3C on the  
finalization of GRDDL and welcomes it as an important addition to the  
Web metadata infrastructure.

    GRDDL is an essential tool in bridging the various expressions  
of Dublin Core metadata, and DCMI is creating GRDDL transforms that  
expose Dublin Core metadata expressed in XML and HTML to the Semantic  
Web.

    By standardizing the transformation mechanisms, GRDDL allows for  
syntactic choices while enabling semantic interoperability -- both  
important needs in the metadata community -- and as such is  
fundamental to the future evolution of the Web.
    -- -- Mikael Nilsson and Thomas Baker, DCMI Architecture Forum,  
Dublin Core Metadata Initiative

    INRIA is proud to have contributed to the specification and  
design of GRDDL and is already promoting and integrating it in  
several projects and tools. Bridging the gap between the traditional  
Web and the Semantic Web is a seminal step in the deployment of  
semantic web technologies and applications. By allowing applications  
to automatically glean resources from the wealth of XML documents  
available online, this recommendation is opening a new highway for  
knowledge mashups and composition of application through web resources.
    -- Pierre Paradinas, Head of Technological Development, INRIA

    Microformats provide an easy way for many people to contribute  
semantic data to the web. With GRDDL all of that data is made  
available for RDF Semantic Web tools. Microformats and GRDDL can work  
together to build a better web.
    -- Ryan King, an active member of microformats.org community

    GRDDL is one of several initiatives from the W3C that seeks to  
unobtrusively evolve the current Web of Documents to a Web of  
interlinked Data.
    -- Kingsley Idehen, CEO, OpenLink Software

    Talis believes that GRDDL represents one of the most important  
steps along the road to the Semantic Web. It provides a very simple  
yet extraordinarily powerful mechanism to uplift documents into the  
web of data. Talis intends to fully support GRDDL in our Semantic Web  
Platform, allowing our customers to automatically extract searchable  
RDF metadata from their existing content with very little effort.
    -- Ian Davis, CTO, Talis Group Ltd.


  L'INRIA est fier d'avoir contribué aux spécifications et à la
  conception de GRDDL et intègre déjà cette technologie dans plusieurs
  projets et outils. Créer des passerelles entre le Web traditionnel  
et le
  Web sémantique est une étape critique dans le déploiement des
  technologies et des applications du Web sémantique. En permettant  
à des
  applications d'extraire automatiquement des données de toute la  
variété
  de documents XML accessibles en ligne, cette recommandation ouvre une
  nouvelle voie pour l'intégration de connaissances et la composition
  d'applications à travers les ressources du Web."
