octubre 5, 2010

jOWL status updateI packaged the latest development version of jOWL into a 0.5 release, available at Google Code. jOWL is an AJAX/javascript extension to jQuery that I am developing. The jOWL library parses and reasons with OWL-DL documents. Supported browsers for this release are Internet Explorer 7 and Firefox 2 & 3.This release is accompanied by several new and impressive demos in my humble opinion. These make use of the new functionalities that have been incorporated so far. Below are some important highlights.

Planning a Semantic Web site

junio 30, 2009

Rob Crowther (robert@crowther.info), Web developer, Freelance

Summary: The Semantic Web brings with it the opportunities for users to get smarter search results, and for site owners to get more targeted traffic as users find what they really want. But these benefits don’t just magically appear. This article leads you through the aspects of both information architecture and general infrastructure you need in place to truly take advantage of this burgeoning opportunity.

This article discusses what you need to know to make your Web site part of the Semantic Web. It starts with a discussion of the problems the Semantic Web tries to solve and then moves to the technologies involved, such as Resource Description Framework (RDF), Web Ontology Language (OWL), and SPARQL Protocol and RDF Query Language (SPARQL). You’ll see how the Semantic Web is layered on top of the existing Web. It then covers some issues that you want to know about when you plan a new Web site and also gives specific examples of how to use technologies like RDFa and Microformats to enable your existing Web site to become a part of the Semantic Web.

Amaya is intended to be a comprehensive client environment for testing and evaluating new proposals for Web standards and formats. A large part of the intended features of Amaya are implemented in this release, but some of them are not complete yet.

Check out the list of new features.

The Amaya binary distribution is available for PC Linux, Windows (NT, XP, 2000) and Mac OS X. Users having other architectures are expected to compile the Amaya source code.

Release schedule

There are about three Amaya releases a year. Between each major release, we may generate patch releases or snapshots which fix important bugs.

Each time a new release is available, an email is sent to the www-amaya mailing list.

Getting the binary distribution

W3C’s Editor/Browser

Amaya is a Web editor, i.e. a tool used to create and update documents directly on the Web. Browsing features are seamlessly integrated with the editing and remote access features in a uniform environment. This follows the original vision of the Web as a space for collaboration and not just a one-way publishing medium.

Work on Amaya started at W3C in 1996 to showcase Web technologies in a fully-featured Web client. The main motivation for developing Amaya was to provide a framework that can integrate as many W3C technologies as possible. It is used to demonstrate these technologies in action while taking advantage of their combination in a single, consistent environment.

Amaya started as an HTML + CSS style sheets editor. Since that time it was extended to support XML and an increasing number of XML applications such as the XHTML family, MathML, and SVG. It allows all those vocabularies to be edited simultaneously in compound documents.

Amaya includes a collaborative annotation application based on Resource Description Framework (RDF), XLink, and XPointer. Visit the Annotea project home page.

Amaya – Open Source

Amaya is an open source software project hosted by W3C. You are invited to contribute in many forms (documentation, translation, writing code, fixing bugs, porting to other platforms…).

The Amaya software is written in C and is available for Windows, Unix platforms and MacOS X.

A public irc channel #amaya is available on irc.w3.org (port 6665).

Amaya Team

The application is jointly developed by W3C and the WAM (Web, Adaptation and Multimedia) project at INRIA. The core team includes: Irène Vatton (Project lead, INRIA), Laurent Carcone (W3C), Vincent Quint (INRIA).
