W3C does not usually send out such long releases, but today's news is
significant. RDF and OWL, two Semantic Web technologies under
development at W3C have been approved as Recommendations today.

The deployment of these standards in commercial products and services
signals the transition of Semantic Web technology from what was largely
a research and advanced development project over the last five years, to
more practical technology deployed in mass market tools that enables
more flexible access to structured data on the Web. As Tim Berners-Lee
explains, "It's not unlike the early days of the Web, when once people
saw how it worked, they understood its power. We're entering that phase
now, where people can see the beginnings of the Semantic Web at work, at
the enterprise level."

http://www.w3.org/ -- 10 February 2004 -- Today, the World Wide Web
Consortium announced final approval of two key Semantic Web
technologies, the revised Resource Description Framework (RDF) and the
Web Ontology Language (OWL). RDF and OWL are Semantic Web standards that
provide a framework for asset management, enterprise integration and the
sharing and reuse of data on the Web. These standard formats for data
sharing span application, enterprise, and community boundaries - all of
these different types of "user" can share the same information, even if
they don't share the same software.

Today's announcement marks the emergence of the Semantic Web as a
broad-based, commercial-grade platform for data on the Web. The
deployment of these standards in commercial products and services
signals the transition of Semantic Web technology from what was largely
a research and advanced development project over the last five years, to
more practical technology deployed in mass market tools that enables
more flexible access to structured data on the Web. Testimonials from
enterprise-scale implementors and independent developers illustrate
current uses of these standards on the Web today.

"RDF and OWL make a strong foundation for Semantic Web applications,"
said Tim Berners-Lee, W3C Director and inventor of the World Wide Web.
"Their approval as W3C Recommendations come at a time when new products
spring up in areas as diverse as Enterprise Integration and medical
decision support. It's not unlike the early days of the Web, when once
people saw how it worked, they understood its power. We're entering that
phase now, where people can see the beginnings of the Semantic Web at work."

A World Wide Web Consortium (W3C) Recommendation is understood by
industry and the Web community at large as a Web standard. Each
Recommendation is a stable specification developed by a W3C Working
Group and reviewed by the W3C Membership. Recommendations promote
interoperability of Web technologies of the Web by explicitly conveying
the industry consensus formed by the Working Group.

Wide Range of Applications Growing from New Semantic Web Standards

Semantic Web-enabled software using RDF and OWL include:

     * Content creation applications: Authors can connect metadata
(subject, creator, location, language, copyright status, or any other
terms) with documents, making the new enhanced documents searchable
     * Tools for Web site management: Large Web sites can be managed
dynamically according to content categories customized for the site managers
     * Software that takes advantage of both RDF and OWL: Organizations
can integrate enterprise applications, publishing and subscriptions
using flexible models
     * Cross-application data reuse: RDF and OWL formats are standard,
not proprietary, allowing data reuse from diverse sources

Many specific examples of commercial applications and enterprise scale
implementations of these technologies are detailed in both the
testimonial page, and the RDF Implementations and OWL Implementations pages.

How the Semantic Web Pieces Fit Together - XML, RDF and OWL

Much has been written about the Semantic Web, as if it is a replacement
technology for the Web we know today. "In reality," countered Eric
Miller, W3C Semantic Web Activity Lead, "it's more Web Evolution than
Revolution. The Semantic Web is made through incremental changes, by
bringing machine-readable descriptions to the data and documents already
on the Web. XML, RDF and OWL enable the Web to be a global
infrastructure for sharing both documents and data, which make searching
and reusing information easier and more reliable as well. "

W3C's Semantic Web Activity builds on work done in other W3C Activities,
such as the XML Activity. Its focus is to develop standard technologies,
on top of XML, that support the growth of the Semantic Web.

XML Provides Rules, Syntax for Structured Documents

At the foundation, XML provides a set of rules for creating vocabularies
that can bring structure to both documents and data on the Web. XML
gives clear rules for syntax; XML Schemas then serve as a method for
composing XML vocabularies. XML is a powerful, flexible surface syntax
for structured documents, but imposes no semantic constraints on the
meaning of these documents.

RDF Delivers a Data Framework for the Web

RDF - the Resource Description Framework - is a standard a way for
simple descriptions to be made. What XML is for syntax, RDF is for
semantics - a clear set of rules for providing simple descriptive
information. RDF Schema then provides a way for those descriptions to be
combined into a single vocabulary. RDF is integrated into a variety of
applications including:

     * library catalogs
     * world-wide directories
     * syndication and aggregation of news, software, and content
     * personal collections of music, photos, and events

In these cases, each uses XML as an interchange syntax. The RDF
specifications provide a powerful framework for supporting the exchange
of knowledge on the Web.

"RDF is part of the foundation of a major advance in the power of the
Web. Ultimately, we will see users and applications combining
information represented in RDF from multiple sources on the Web in ways
that, until now, have been inconceivable," explains Brian McBride, Chair
of the RDF Core Working Group, "The RDFCore Working Group has turned the
RDF specifications into both a practical and mathematically precise
foundation on which OWL and the rest of the Semantic Web can be built."

OWL Delivers Ontologies that Work on the Web

What's needed next is a way to develop subject - or domain - specific
vocabularies. That is the role of an ontology. An ontology defines the
terms used to describe and represent an area of knowledge. Ontologies
are used by people, databases, and applications that need to share
subject-specific (domain) information - like medicine, tool
manufacturing, real estate, automobile repair, financial management,
etc. Ontologies include computer-usable definitions of basic concepts in
the domain and the relationships among them. They encode knowledge in a
domain and also knowledge that spans domains. In this way, they make
that knowledge reusable.

OWL - the Web Ontology Language - provides a language for defining
structured, Web-based ontologies which delivers richer integration and
interoperability of data among descriptive communities. Where earlier
languages have been used to develop tools and ontologies for specific
user communities (particularly in the sciences and in company-specific
e-commerce applications), they were not defined to be compatible with
the architecture of the World Wide Web in general, and the Semantic Web
in particular.

OWL uses both URIs for naming and the description framework for the Web
provided by RDF to add the following capabilities to ontologies:

     * Ability to be distributed across many systems
     * Scalability to Web needs
     * Compatibility with Web standards for accessibility and
     * Openness and extensibility

OWL builds on RDF and RDF Schema and adds more vocabulary for describing
properties and classes: among others, relations between classes (e.g.
disjointness), cardinality (e.g. "exactly one"), equality, richer typing
of properties, characteristics of properties (e.g. symmetry), and
enumerated classes.

"OWL takes a major step forward in representing and organizing knowledge
on the World Wide Web. It strikes a sound balance between the needs of
industry participants for a language which addresses their current Web
use cases, and the restrictions on developing an ontology language that
meshed with established scientific principles and research experience,"
explained Jim Hendler and Guus Schreiber, co-chairs for the Web Ontology
Working Group. "Over fifty Working Group members have successfully
designed a language that addresses both sets of concerns and is endorsed
by academics and practitioners alike."

RDF and OWL Documents Include Primers, Use Cases, Test Suites, to Aid

The W3C RDF Core Group has produced six documents. Each is aimed at
different segments of those wishing to learn, use, implement or
understand RDF. The RDF Primer is an introduction to, and tutorial on
how to use, RDF and RDF Schema. RDF Concepts and Abstract Syntax
specifies the fundamental concepts and information model of RDF. The
RDF/XML Syntax Specification (Revised) defines how to write RDF in XML
syntax. RDF Vocabulary Description Language 1.0: RDF Schema describes
how to use RDF to describe application and domain specific vocabularies.
RDF Semantics defines the mathematically precise formal semantics of RDF
and RDF Schema. RDF Test Cases defines a set of test cases that
illustrate aspects of the other specifications and may be used for the
automatic testing of implementations.

The W3C Web Ontology Working Group has produced six OWL documents. Each
is aimed at different segments of those wishing to learn, use, implement
or understand the OWL language. Documents include - a presentation of
the use cases and requirements that motivated OWL - an overview document
which briefly explains the features of OWL and how they can be used - a
comprehensive Guide that walks through the features of OWL with many
examples of the use of OWL features - a reference document that provides
the details of every OWL feature - a test case document, and test suite,
providing over a hundred tests that can be used for making sure that OWL
implementations are consistent with the language design - a document
presenting the semantics of OWL and details of the mapping from OWL to RDF.

As the leading provider of content creation tools to help people
communicate better, adding intelligence to media via metadata was
integral to our strategy. We developed Adobe XMP (Extensible Metadata
Platform) based on RDF, because it provided a flexible and interoperable
framework for fostering the capture, preservation, and interchange of
metadata across digital media and workflows. The Adobe Creative Suite
provides a design platform that enables creative professional to create
information rich assets powered by XMP that can be more effectively
repurposed and consumed across multiple media and diverse domains.

Brandsoft’s product offerings are one of the first commercial
implementations of Semantic Web components, mainly RDF. Our belief is
that enterprises that standardize on a common metadata framework, like
RDF, will gain significant value, agility, and substantial cost
reduction. They will also benefit from the ability to provide value
added services and applications within their extended enterprise
community (employees, customers, partners, etc.). As a result of using
RDF, Brandsoft has developed a standards based platform with the ability
to integrate the various tools needed to: Create, manage and reuse
content; Publishing capabilities for differing languages, media, and
devices; Establish relationships between people, processes, and systems

Technology (ILRT), University of Bristol

The efforts of Creative Commons to encourage permitted sharing and reuse
of works are greatly enhanced by the availability and continued
development of RDF, which serves as the machine-readable layer for our
"some rights reserved" licenses. One year after launch there are over
one million Creative Commons-licensed works published on the web,
supported by RDF-aware blog, browser, graphics, music, publishing,
search and validation applications and services. The upcoming new and
revised components of the RDF specification suite will provide a great
boost to the understanding and adoption of RDF, and thus our work to
cultivate an ecology of Creative Commons-aware software.

Fujitsu Laboratories of America - College Park is currently using OWL as
an integral part of our work on "Task Computing." Task Computing is a
novel integration of the Semantic Web with Web Services to provide users
with easier ways of achieving complicated goals in mobile and/or
ubiquitous computing environments. Ontologies defined in OWL give us a
powerful mechanism for reasoning about the composition of heterogeneous
services and the use of Web Services lets us access real devices and
displays. Together they enable new and rich forms of interaction between
users and their computing environment. The standardization of OWL and
RDF will facilitate the acceptance of innovative software methods such
as Task Computing.

IBM has a history of using progressive research to deliver business
value today and in the future. Our research work with the Semantic Web
has the potential to open the Internet to even more powerful
applications. Within IBM we have many active research projects working
with both RDF and OWL. Our first public Semantic Web project, SnoBase,
released on AlphaWorks, is a framework for loading ontologies from files
and using the Internet for locally creating, modifying, querying, and
storing ontologies. It provides a mechanism for querying ontologies and
an easy-to-use programming interface for interacting with vocabularies
of standard ontology specification languages including RDF, RDF Schema,
and OWL. SnoBase can help a broad range of business applications that
need knowledge sharing and reuse as well as information search and
navigation by using reasoning within a generic management environment.

McDonald Bradley, Inc. (MBI) is leveraging the expressiveness and
flexibility of the Resource Description Framework (RDF) today in its
support of many Department of Defense and Intelligence Community
customers. Specifically, the RDF model was a core design feature of the
DOD Discovery Metadata Specification (DDMS) Schema. RDF achieving the
status of W3C Recommendation will increase the number of tools while
stabilizing their maturity and features. This will enable MBI to better
deliver robust Semantic Web applications to its customers as they move
towards Net-Centric applications.

-- Michael C. Daconta, Chief Scientist, Advanced Programs Group, MBI

Mondeca is happy to welcome the advancement of OWL to W3C
recommendation. Always eager to make its technology conformant to the
widest range of semantic standards, the company has started to use OWL
since mid-2003 in customers applications, to describe and set up
knowledge models in its ontology-driven knowledge management platform, ITM.
ITM ontology layer was beforehand specified using proprietary internal
representation. Using OWL provides ITM with new capacity to describe it
in a standard and interoperable format, to re-use customer-defined or
public domain ontologies, and paves the way to future developments
integrating the power of inference tools.

-- Bernard Vatant, Senior Consultant, Knowledge Engineering, Mondeca

RDF gives us a data model for describing information organization
structures (metadata) for collections of networked information. Mozilla
uses it as a standard way to represent the many different structures we
use to organize the various kinds of information we handles --- from
bookmarks and email folders to address books and web services. RDF
remains important on the browser side not only because of these current
uses but also because of developing trends such as web logs and news
feeds that are based on RDF. This ability to deal with meta-data
independent of the protocols and formats associated with the data is
essential in moving the web forward.

-- Ben Goodger, Lead Engineer, Mozilla Firebird, The Mozilla Foundation

Network Inference congratulates the co-chairs and members of the W3C's
Web-Ontology (WebOnt) Working Group for their outstanding work on OWL.

The University of Southampton and the Advanced Knowledge Technologies
interdisciplinary research collaboration (AKT IRC) enthusiastically
endorse the W3C Resource Description Framework recommendations. The RDF
suite of specifications are fundamentally important to the success of
the W3C's Semantic Web initiative. RDF provides a common framework for
the expression of metadata and metadata schemata. Such metadata support
the semantic annotation of Web content and services, which underpin
knowledge integration and exchange. A number of leading research
projects within the University and AKT IRC are making extensive use of
RDF, including our scalable open-source RDF repository software, 3store.

The University of Southampton and the Advanced Knowledge Technologies
interdisciplinary research collaboration (AKT IRC) enthusiastically
endorse the W3C OWL Web Ontology Language recommendation, a key
specification in the W3C's Semantic Web initiative. OWL permits the
definition of sophisticated ontologies, a fundamental requirement in the
integration of heterogeneous information content. OWL ontologies will
also be important for the characterization of interoperable services for
knowledge-intensive processing on the Web. Research on next-generation
products and services within the University and AKT IRC is incorporating
OWL as standard.

-- Professor Nigel Shadbolt (Director), Professor David De Roure (Head
of Grid and Pervasive Computing), and Dr Nicholas Gibbins, AKT IRC,
