An introduction to RDF, a large and growing list of RDF resources, and an RSS feed of the list so you can keep up to date.

Kowari is an open-sourced (Mozilla Public License) triplestore optimized for RDF storage, created by Tucana Technologies, and written entirely in Java 1.4.2. It began its life as the storage component of the Tucana Knowledge Server (TKS), Tucana's proprietary knowledge management suite, and remains under active development by Tucana.

Around 30 people attended the Practical RDF Town Hall at the XML 2003 conference this week, watching demos and asking questions.

Short collection of RDF Queries taken from RDF Query and Rules: A Framework and Survey and XQuery examples provided by Jerome Simeon, Damian Steer, and Jonathan Robie's The Syntactic Web. Thanks to Paul Turner for helping put the slides together.

In this paper Qualified Dublin Core is encoded in terms of RDF, the Resource Description Framework as defined by the RDF Model & Syntax Specification (XML namespace for RDF).

This is a language which is a compact and readable alternative to RDF's XML syntax, but also is extended to allow greater expressiveness. It has subsets, one of which is RDF 1.0 equivalent, and one of which is RDF plus a form of RDF rules.

Somebody, I think it was Adam Bosworth of BEA, once said that every layer of abstraction costs you 50% of your audience. Or words to that effect. Let's do the math. You are presenting on the subject of a new business IT architecture to an audience of 100 people. You start with people and business processes at the bottom of your diagram. You add layers of abstraction on top so that everything fits neatly into some nice three letter acronym-emblazoned box at the top. Let's call the top level box XYZ for the sake of argument. The XYZ acronym becomes a strategy buzzword of the enterprise.

This document introduces the RDFWeb system, providing an overview of the technology, ambitions and architecture behind the project. While RDFWeb relies heavily on the W3C specifications for the Resource Description Framework (RDF), this document stands alone as a complete description of the system. A brief introduction of the RDF information model is provided for the curious.

There is a sentiment in the Web Application community that RDF is 'hard'.

With RSS we have the ability grab news and summaries from other websites and display them on our portals. However, a key property of news is that they describe something that just happened. Therefore the most interesting news are the newest news.

At the Event UKOLN RDF Seminar, Bath. ... The seminar opened with Renato Iannella, from
DSTC Pty Ltd, giving a brief overview of what RDF is and where it came from. ...

I'm trying to flesh out some of the details of TimBL's semantic web toolbox... to build some layers on top of RDF such as horn clauses ala SHOE (see SHOE->RDF materials which so far just xhtml-ize SHOE).

The document describes RDQL (RDF Data Query Language) which has been implemented in a number of RDF systems for extracting information from RDF graphs. First, there is a brief introduction to the language, then a more formal description of the grammar.

This is the first public draft of a discussion document for the RDF Interest Group. This document has no formal standing within W3C Process. If there is sufficient interest in the approach outlined here, future versions of this work might be published as W3C Notes. This document is a work in progress, and does not represent the activity of any chartered working group within W3C process.

There have been assertions of an "RDF Tax". Not having an opinion on the subject, I decided to do a little investigating. In particular, I sought to identify the highest potential "ceiling" to the RDF tax.

This document presents a series of examples of the use of RDF syntax in encoding Dublin Core metadata records.

RDF - the Ressource Description Framework - is a foundation for processing metadata; it provides interoperability between applications that exchange machine-understandable information on the Web. RDF emphasizes facilities to enable automated processing of Web ressources. RDF metadata can be used in a variety of application areas; for example: in resource discovery to provide better search engine capabilities; in cataloging for describing the content and content relationships available at a particular web site, page or digital library; by intelligent software agents to facilitate knowledge sharing and exchange; in content rating; in describing collections of pages that represent a single logical "document"; for describing intellectual proberty rights of Web pages, and in many others. RDF with digital signatures will be key to building the "Web of Trust" for electronic commerce, collaboration, and other applications.

(Within this document, XML elements with namespace prefix are assumed to be defined as pointing to something the reader can figure out, and unprefixed element names are used for new features which are introduced in this document. ). The major difference between this syntax and RDF 1.0 M&S is that RDF edges correspond to elements, and RDF nodes are implicit. It is basically as the M&S syntax with parseType=resource is a default.

This paper introduces RDF, the Resource Description Framework, as an emerging standard for metadata on the World Wide Web. RDF, if accepted by the web community, can provide simple knowledge representation facilities for the web. We argue that distributed applications of the future, possibly based on multiagent technologies, not only would greatly benefit from universally available facilities for knowledge representation, but actually require them to function productively.

This RDF parser is designed to run in a web-browser or SVG browser, allowing you to process RDF on the client. The parser isn't complete, there's no support for various bits of the spec, and isn't all that fast, especially with large XML/RDF files. I've found it quite useful though for simple querying, it also does some attempt at subProperties, if the rdfs exists in the RDF.
