Hello,
W3C issued a press release today:
From Chaos, Order: W3C Standard Helps Organize Knowledge
SKOS Connects Diverse Knowledge Organization Systems to Linked Data
http://www.w3.org/2009/07/skos-pr
The text of the press release (without links) and additional resources
follows.
http://www.w3.org/ -- 18 August 2009 -- Today W3C announces a new
standard that builds a bridge between the world of knowledge
organization systems — including thesauri, classifications, subject
headings, taxonomies, and folksonomies — and the linked data
community, bringing benefits to both. Libraries, museums,
newspapers, government portals, enterprises, social networking
applications, and other communities that manage large collections of
books, historical artifacts, news reports, business glossaries, blog
entries, and other items can now use Simple Knowledge
Organization System (SKOS) to leverage the power of linked data. As
different communities with expertise and established vocabularies
use SKOS to integrate them into the Semantic Web, they increase the
value of the information for everyone.
SKOS Adapts to the Diversity of Knowledge Organization Systems
A useful starting point for understanding the role of SKOS is the
set of subject headings published by the US Library of Congress
(LOC) for categorizing books, videos, and other library resources.
These headings can be used to broaden or narrow queries for
discovering resources. For instance, one can narrow a query about
books on "Chinese literature" to "Chinese drama," or further still
to "Chinese children's plays."
Library of Congress subject headings have evolved within a community
of practice over a period of decades. By now publishing these
subject headings in SKOS, the Library of Congress has made them
available to the linked data community, which benefits from a
time-tested set of concepts to re-use in their own data. This re-use
adds value ("the network effect") to the collection. When people all
over the Web re-use the same LOC concept for "Chinese drama," or a
concept from some other vocabulary linked to it, this creates many
new routes to the discovery of information, and increases the
chances that relevant items will be found. As an example of mapping
one vocabulary to another, a combined effort from the STITCH,
TELplus and MACS Projects provides links between LOC concepts and
RAMEAU, a collection of French subject headings used by the
Bibliothèque Nationale de France and other institutions.
SKOS can be used for subject headings but also many other approaches
to organizing knowledge. Because different communities are
comfortable with different organization schemes, SKOS is designed to
port diverse knowledge organization systems to the Web.
"Active participation from the library and information science
community in the development of SKOS over the past seven years has
been key to ensuring that SKOS meets a variety of needs," said
Thomas Baker, co-chair of the Semantic Web Deployment Working
Group, which published SKOS. "One goal in creating SKOS was to
provide new uses for well-established knowledge organization systems
by providing a bridge to the linked data cloud."
SKOS is part of the Semantic Web technology stack. Like the Web
Ontology Language (OWL), SKOS can be used to define vocabularies.
But the two technologies were designed to meet different needs. SKOS
is a simple language with just a few features, tuned for sharing and
linking knowledge organization systems such as thesauri and
classification schemes. OWL offers a general and powerful framework
for knowledge representation, where additional "rigor" can afford
additional benefits (for instance, business rule processing).
