Semantic World is a web community dedicated to the use of semantic information management methods in industry. Semantic World contains relevant news and analysis, a comprehensive resource center, and interactive forums for practitioners of semantic methodologies to share experiences, problems, and initiatives. Semantic World aims to support and influence developing standards for ontology modeling, semantic mapping, and the use of semantic information management methods in IT.

Very comprehensive information site concentrating on XML,RDF and OWL. Contains tutorials, worked examples and news. Excellent resources and starting point.

This site is the home page of Ontology.Org, the consortium of organisations and individuals developing knowledge level models and representations of electronic marketplaces.

TRIPLE is an RDF query, inference, and transformation language for the Semantic Web. Instead of having a built-in semantics for RDF Schema (as many other RDF query languages have), TRIPLE allows the semantics of languages on top of RDF (like RDF Schema, Topic Maps, UML, etc.) to be defined with rules. For languages where this is not easily possible (e.g., DAML+OIL), access to external programs (like description logics classifiers) is provided. As a result, TRIPLE allows RDF reasoning and transformation under several different semantics, which is necessary if you need to access multiple data source in one application (e.g., for data integration).

An Intelligent Brokering Service for Knowledge-Component Reuse on the World-Wide Web. The objective of IBROW is to develop intelligent brokers that are able to distributively configure reusable components into knowledge systems through the World-Wide Web. The WWW is changing the nature of software development to a distributive plug & play process, which requires a new kind of managing software: intelligent software brokers. IBROW will integrate research on heterogeneous DB, interoperability and Web technology with knowledge-system technology and ontologies.

OWL is a semantic markup language for publishing and sharing ontologies on the World Wide Web. OWL is derived from the DAML+OIL Web Ontology Language [DAML+OIL] and builds upon the Resource Description Framework

Modulant - The Interoperability Company. Modulant is an enterprise software developer of semantics-based information interoperability solutions.

The Karlsruhe Ontology (KAON) tool suite builds on RDF and provides specialized tools including: SDK, engineering, discovery, management and presentation of ontologies and metadata. Site includes middleware downloads, whitepapers, specifications and demonstrations. A practical web resource for Semantic web development.

The Web Ontology Working Group is chartered to build upon the RDF Core work a language for defining structured web based ontologies which will provide richer integration and interoperability of data among descriptive communities.

OpenCyc is the open source version of the Cyc technology, the world's largest and most complete general knowledge base and commonsense reasoning engine. Developers can use CycML to exchange knowledge with one another, and CycML will also allow the KB contents to be imported and exported for archiving.

Web-IQ.com is a software research and development company specializing in Semantic Web Services.

OpenCyc is the open source version of the Cyc technology, the worlds largest and most complete general knowledge base and commonsense reasonging engine. Cycorp, the builders of Cyc, have set up an independent organization, OpenCyc.org, to disseminate and administer OpenCyc, and have committed to a pipeline through which all current and future Cyc technology will flow into ResearchCyc (available for R&D in academia and industry) and then OpenCyc.

Unicorn has developed a comprehensive architecture for the next generation of data infrastructure. Unicorn enables the enterprise to leverage the value of disparate information assets in a unified information model.

This is the community site for Ontoweb, a European Union founded project about Ontology-based information exchange for knowledge management and electronic commerce.

iMorph is a technology provider specializing in the transformation of information for dynamic web implementation.

Through our website, whitepapers, and consulting services, Semaview aims to be the world leader of semantic technologies.

Summary of existing resources, articles and references on the OWL Web Ontology Language

The objectives are to develop a roadmap for cutting edge research and commercial application of new web technology, specifically to position RTD projects in Framework VI. Semantic Web, Web Services, and their combination may promise a large stream of successful IST projects helping key action III to strengthen its profile of hosting leading research projects with world wide visibility and impact.

OilEd is a simple ontology editor which allows the user to build ontologies using OIL. The intention behind OilEd is to provide a simple, freeware editor that demonstrates the use of, and stimulates interest in, OIL. OilEd is not intended as a full ontology development environment. The OilEd executable is available as freeware.

KTweb brings together the European projects and people working in information access and knowledge technologies - in research, academia and business - and offers information and resources in these domains at a global level. An good starting point for knowledge technologies information.
