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. ...

rdfDB is intended to be a simple, scalable, open-source database for RDF for systems like Semantic Web Services.

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).

This document explores some examples based around the idea of extending RSS using RDF-based modularisation, and then querying the resulting data in ways that exploit those extensions.

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.

The ICS-FORTH Validating RDF Parser (VRP v2.5) is a tool for analyzing, validating and processing RDF schemas and resource descriptions. The Parser analyses syntactically the statements of a given RDF/ XML file according to the RDF M&S Specification (more precisely, the updated syntax proposed by W3C Working Draft 23 January 2003).

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.

This document is a WorkInProgress and will be updated as new RDF examples and tests are made available.

This document describes the RDF Test Cases deliverable for the RDF Core Working Group as defined in the WG's Charter.

Automatic metadata generation may provide a solution to the problem of inconsistent, unreliable metadata describing resources on the Web. The Resource Description Framework (RDF [10]) provides a domain-neutral foundation on which extensible element sets can be defined and expressed in a standard notation. This paper describes how an automatic classifier, that classifies HTML documents according to Dewey Decimal Classification (DDC [8]), can be used to extract context sensitive metadata which is then represented using RDF.

The Resource Description Framework (RDF) is a general framework for how to describe any Internet resource such as a Web site and its content. An RDF description (such descriptions are often referred to as metadata, or "data about data") can include the authors of the resource, date of creation or updating, the organization of the pages on a site (the sitemap), information that describes content in terms of audience or content rating, key words for search engine data collection, subject categories, and so forth. The Resource Description Framework will make it possible for everyone to share Web site and other descriptions more easily and for software developers to build products that can use the metadata to provide better search engines and directories, to act as intelligent agents, and to give Web users more control of what they're viewing. The RDF is an application of another technology, the Extensible Markup Language (XML), and is being developed under the auspices of the World Wide Consortium (W3C).
