Knowledge organisation systems, such as taxonomies, thesauri or subject heading lists, play a fundamental role in information structuring and access. The Semantic Web Deployment Working Group aims at providing a model for representing such vocabularies on the Semantic Web: SKOS (Simple Knowledge Organisation System). This document presents the preparatory work for a future version of SKOS. It lists representative use cases, which were obtained after a dedicated questionnaire was sent to a wide audience. It also features a set of fundamental or secondary requirements derived from these use cases, that will be used to guide the design of SKOS.

Some information observers have suggested that Web 2.0's rise has been due to software applications, while it is becoming increasingly obvious to futurists that the Semantic Web will be defined by services. How those services will be developed and leveraged to bring order to the Web is central to our discussion of the Semantic Web. We discuss the broad implications of these issues through a lens of our work as library professionals, and the time we spend blogging about information on the Web, and its evolution.

The Resource Description Framework (RDF), a method of connecting URIs in a meaningful way, is the key to making the Semantic Web possible.

my idea for further Web “upgrades”:

Built on Semantic Web technologies, hakia is a new "meaning-based" (semantic) search engine with the purpose of improving search relevancy and interactivity -- the potential benefits for end users are search efficiency, richness of information, and saving time.

My colleague Dean Giustini and I have collaborated on an article, The Semantic Web as a large, searchable catalogue: a librarian’s perspective. In it, we argue that librarians will play a prominent role in Web 3.0. The current Web is disjointed and disorganized, and searching is much like looking for a needle in the haystack.

Tim Berners Lee on the Semantic Web

 Despite its explosive growth over the last decade, the Web remains essentially a tool to allow humans to access information. The next generation of the Web, dubbed the ‘Semantic Web’, will extend the Web’s capability through the increased availability machine-processable information. These machine-processable descriptions of Web information resources are called meta-data and are associated with ontologies, or conceptualisations of the domain of application. Meta-data and associated ontologies then allows more intelligent software systems to be written, automating the analysis and exploitation of Web-based information.This paper describes how knowledge management can be improved through the adoption of Semantic Web technology. To realise this, a number of different technologies need to be brought together. Their fusion provides the infrastructure which makes semantic knowledge management possible. Specifically, the paper discusses the use of knowledge discovery and human language technology to (semi-)automatically derive the required ontologies and meta-data, along with a methodology to support this process. We describe techniques for management and controlled evolution of ontologies and a set of semantic knowledge access tools for enhanced information access. Finally, a set of application scenarios for the technology are sketched.

This summary in 10 points attempts to capture enough of the basic concepts to enable a beginner to see the forest through the trees.

The most exciting uses of RDF aren't in encoding information about web resources, but information about and relations between things in the real world: people, places, concepts, etc.

On the Semantic Web (SemWeb), computers do the browsing (and searching, and querying, and...) for us. The SemWeb enables computers to seek out knowledge distributed throughout the Web, mesh it, and then take action based on it. Take an analogy: the current web is a decentralized platform for distributed presentations, while the SemWeb is a decentralized platform for distributed knowledge. Resource Description Framework (RDF) is the W3C standard for encoding knowledge.
