RDQL is an implementation of an SQL-like query language for RDF. It treats RDF as data and provides query with triple patterns and constraints over a single RDF model. Part of the HP Labs Semantic Web resources.

RDFWeb is an experimental linked information system, where the linked items are machine-understandable documents in the World Wide Web. These documents, written in the XML, RDF and XHTML languages, are harvested by our Web indexing programs, which then merge the resulting information to form one big database. By exploiting various features of the RDF technology alongside related tools such as digital signature, we can use the Web to retrieve structured information that machines can process and act upon. RDFWeb is best understood as an exploration of the question: what would it be like if machines could read what we say in our Web homepages?

WC3 home page for RDF. The Resource Description Framework (RDF) integrates a variety of applications from library catalogs and world-wide directories to syndication and aggregation of news, software, and content to personal collections of music, photos, and events using XML as an interchange syntax. The RDF specifications provide a lightweight ontology system to support the exchange of knowledge on the Web.

The FRODO RDFSViz tool provides a visualization service for ontologies represented in RDF Schema. Status of the development and a demonstration environment are available.

MusicBrainz provides an extensive database of music related information based on RDF. Described as an open music encyclopedia. Impressive demonstration of the practical value-add of using RDF.

Comprehensive list of resources covering publications, press, discussion, contacts, editors and tools, applications and much, much more. Available in RSS format for the truly committed.

RDFWeb is an experimental linked information system. RDFWeb explores some interconnected applications of the semantic web. It features a distributed RDF-indexed photo archive, the friend-of-a-friend information linking system, and various other fun things.
