Topic maps and RDF originate from two standards organizations, ISO and the W3C respectively, that have traditionally been regarded as competitors. This accounts to some extent for the tendency among the uninformed to regard topic maps and RDF as competitors. Our position is that it makes more sense to regard topic maps and RDF as complementary, and to look for ways of realizing the potential synergies between the two. Ontopia has clearly demonstrated this potential through its use of RDF (under the covers, as it were) in the automated generation of topic maps.

The world of the semantic web, as based on RDF, is really simple at the base. This article shows you how to get started. It uses a simplified teaching language -- Notation 3 or N3 -- which is basically equivalent to RDF in its XML syntax, but easier to scribble when getting started.

This page summarizes some current approaches to storing RDF in a relational database. THIS IS A REQUEST FOR COMMENTS, so please do contribute your ideas (www-rdf-interest@w3.org)! To goal is to come up with the best way of storing RDF in a relational database, or identify a set of solutions that are suitable for particular needs.

Let me now explain what this document is for. It isn't intended to replace either Tim's high-level explanation, or the detailed formalism of the draft. Instead, it attempts to explain RDF from the simple cases to the general cases rather than the other way around. After reading this document, you should know how to encode Properties in XML in a way that complies with RDF.

Welcome to RDFWeb's 'Friend of a Friend' (FOAF) project developer site. RDFWeb is an experimental linked information system, exploring some interconnected applications of the Semantic Web, beginning with the deployment of FOAF.

Since there is no one standardized approach for associating RDF compatible metadata with HTML, and since this is one of the most frequently asked questions on the RDF mailing lists, this document is provided as an outline of some RDF-in-HTML approaches that the author is aware of.

This note is an attempt to answer the question, "Why should I use RDF - why not just XML?". This has been a question which has been around ever since RDF started. At the W3C Query Language workshop, there was a clear difference of view between those who wanted to query documents and those who wanted to extract the "meaning" in some form and query that. This is typical. I wrote this note in a frustrated attempt to explain whatthe RDF model was for those who though in terms of the XML model.

This note specifies a Resource Description Framework (RDF) encoding of the vCard profile defined by RFC 2426 and to provide equivalent functionality to its standard format. The motivation is to enable the common and consistent description of persons (using the existing semantics of vCard) and to encode these in RDF/XML.

This is a draft of an RDF API provided for a public discussion. The API defines interfaces for parsing (org.w3c.rdf.syntax) and accessing RDF models as sets of statements (org.w3c.rdf.model). Default implementations for those interfaces are included in the org.w3c.rdf.implementation package.

Resource Description Framework (RDF) is a standard for describing resources on the web. This guide contains links to many RDF resources including examples, documents, software, tools and projects that use it.

RDF Site Summary (RSS) is a lightweight multipurpose extensible metadata description and syndication format. RSS is an XML application, conforms to the W3C's RDF Specification and is extensible via XML-namespace and/or RDF based modularization.

This document defines an XML syntax for RDF called RDF/XML in terms of Namespaces in XML, the XML Information Set and XML Base. The formal grammar for the syntax is annotated with actions generating triples of the RDF graph as defined in RDF Concepts and Abstract Syntax. The triples are written using the N-Triples RDF graph serializing format which enables more precise recording of the mapping in a machine processable form. The mappings are recorded as tests cases, gathered and published in RDF Test Cases.

This online service has been updated and now supports the Last Call Working Draft specifications issued by the RDF Core Working Group, including datatypes. Deprecated elements and attributes of the standard RDF Model and Syntax Specification are no longer supported.
