Semanticweb.org
The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. It has been described in rather different ways: as a utopic vision, as a web of data, or merely as a natural paradigm shift in our daily use of the Web. Most of all, the Semantic Web has inspired and engaged many people to create innovative semantic technologies and applications. semanticweb.org is the common platform for this community. You can extend semanticweb.org. Make sure that your favourite semantic tool, event, or ontology is here! Task Force Spam Fighting

RDF Primer The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. Top-Down: A New Approach to the Semantic Web Earlier this week we wrote about the classic approach to the semantic web and the difficulties with that approach. While the original vision of the layer on top of the current web, which annotates information in a way that is "understandable" by computers, is compelling; there are technical, scientific and business issues that have been difficult to address. One of the technical difficulties that we outlined was the bottom-up nature of the classic semantic web approach. Specifically, each web site needs to annotate information in RDF, OWL, etc. in order for computers to be able to "understand" it.

Infobox An infobox may be implemented in another document by transcluding it into that document and specifying some or all of the attribute–value pairs associated with that infobox, known as parameterization. Wikipedia[edit] Baeza-Yates and King say that some editors find templates such as infoboxes complicated, as the template may hide text about a property or resource that the editor wishes to change; this is exacerbated by chained templates, that is templates transcluded within other templates.

Semantic Forms Semantic Forms is an extension to MediaWiki that allows users to add, edit and query data using forms. It is heavily tied in with the Semantic MediaWiki extension, and is meant to be used for structured data that has semantic markup. Having Semantic MediaWiki installed is a precondition for the Semantic Forms extension; the code will not work without it. Online Access The DBpedia data set can be accessed online via a SPARQL query endpoint and as Linked Data. 1. Querying DBpedia The DBpedia data set enables quite astonishing query answering possibilities against Wikipedia data. 1.1. RDF/OWL Representation of WordNet Abstract This document presents a standard conversion of Princeton WordNet to RDF/OWL. It describes how it was converted and gives examples of how it may be queried for use in Semantic Web applications. Status of this Document

Semantic Web Patterns: A Guide to Semantic Technologies In this article, we'll analyze the trends and technologies that power the Semantic Web. We'll identify patterns that are beginning to emerge, classify the different trends, and peak into what the future holds. In a recent interview Tim Berners-Lee pointed out that the infrastructure to power the Semantic Web is already here. Optimus—Microformats Transformer What is it? Optimus—is a microformats transformer. Easily transform your microformatted content to nice, clean, easily digestible, XML, JSON or JSON-P. You can also easily set filters to only receive particular formats. Now your web site could really be your API with goodness of microformats and power of Optimus. How to use it?

Semantic Maps The Semantic Maps extension adds semantic capabilities to the Maps extension. This includes the ability to add, edit, aggregate and visualize coordinate data stored through the Semantic MediaWiki extension. Since Semantic Maps uses the Maps API, you can use multiple mapping services. These include Google Maps (with Google Earth support), Yahoo! AceWiki AceWiki is a semantic wiki that is powerful and at the same time easy to use. Making use of the controlled natural language ACE, the articles in the wiki are composed of formal statements that look like natural English. Demos See the following demo video for a first impression of AceWiki:

SemanticWebTools - W3C Wiki REDIRECT New SemanticWiki Tools Page As of 12:50, 14 January 2010, this page is no longer maintained and should not be changed. The content has been transferred to Semantic Web W3C's Semantic Web logo The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C).[1] The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web, dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF).[2] According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.

Microformat A microformat (sometimes abbreviated μF) is a web-based approach to semantic markup which seeks to re-use existing HTML/XHTML tags to convey metadata[1] and other attributes in web pages and other contexts that support (X)HTML such as RSS. This approach allows software to process information intended for end-users (such as contact information, geographic coordinates, calendar events, and similar information) automatically. Although the content of web pages is technically already capable of "automated processing", and has been since the inception of the web, such processing is difficult because the traditional markup tags used to display information on the web do not describe what the information means.[2] Microformats can bridge this gap by attaching semantics, and thereby obviate other, more complicated, methods of automated processing, such as natural language processing or screen scraping. Background[edit] Neither CommerceNet nor Microformats.org operates as a standards body.

Tools This page gives an overview of software tools related to the Semantic Web or to semantic technologies in general. Due to the large amount of tools being created in the community, this site is always somewhat outdated. Contributions and updates are welcomed. See also: Tool Chains
