About this capture

COLLECTED BY

Organization: Internet Archive

The Internet Archive discovers and captures web pages through many different web crawls. At any given time several distinct crawls are running, some for months, and some every day or longer. View the web archive through the Wayback Machine.

Collection: Wide Crawl started September 2012

Web wide crawl with initial seedlist and crawler configuration from September 2012.

TIMESTAMPS

Web Ontology Language (OWL)

6 September 2007: W3C Launches the OWL Working Group.

A. OWL is a Web Ontology language. 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 internationalization
• Openess and extensiblility

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.

To participate in the development of the next versions of OWL, consider joining the OWL Working Group.

OWL Specification Development

The OWL suite of specifications consist of:

• OWL Web Ontology Language Overview
  W3C Recommendation 10 Feb 2004. Deborah L. McGuinness and Frank van Harmelen eds.

  formerly Feature Synopsis for OWL Lite and OWL

  The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics. OWL has three increasingly-expressive sublanguages: OWL Lite, OWL DL, and OWL Full.

Tutorials

A set of tutorials on OWL and related Semantic Web technologies is maintained by the Semantic Web Best Practices and Deployment Working Group.

Articles and Presentations

We do not currently keep a separate list of OWL presentations and articles. See the Semantic Web presentations, W3C in The Press and Resource Description Framework Press.

Tools, Projects and Applications

The following is a small sample of the growing set of tools, projects and applications utilizing OWL.

Demos / Portals

• AIFB SEmantic PortAL - The Institute AIFB web site of the University of Karlsruhe provides annotated pages which contain dynamically generated machine processable content in form of OWL annotations.
• The AKT Portal at the University of Southampton is largely based on ontologies, and is now using OWL.
• The University of Maryland Baltimore County (Finin) has developed two demos using OWL ( Finin 7May)
• BioPax - A Data Exchange Format for Biological Pathways has been using OWL
• The W3C tech reports - related to the "multimedia collections" use case
• ( The MINDSWAP project web site) uses OWL to generate all the web pages and "custom home pages" for members of the research group, as well as for doing photo markup. ( Hendler 6May)
• The OWL-generated Comment Status List submitted for the CR request for OWL was generated by a combination of OWL tools.

The listing of developer’s tools on this page has been removed in July 2006, in favor of the more comprehensive page on the W3C Wiki. By moving this list to the Wiki, the Semantic Web community at large can contribute in keeping that information up-to-date.

Ontologies

• SchemaWeb provides a comprehensive directory of RDF schemas and OWL ontologies to be browsed and searched by human agents and also an extensive set of web services to be used by agents and reasoning software applications that wish to obtain real-time schema information.
• DAML Ontology Library which organizes hundreds of ontologies in a variety of different ways (keyword, organization, submission date, etc.)
• Swoogle is a search engine for Semantic Web documents, including OWL ontologies, built by the University of Maryland Baltimore County under funding from the National Science Foundation.
