In an attempt to summarize the relationship among various metadata formats and how they relate to building Internet systems I wrote a glossary. I then ordered and tied the terms together with a bit of narrative to explain the relationships among the terms

"Swoogle is a search engine for the Semantic Web on the Web. Swoogle crawl the World Wide Web for a special class of web documents called Semantic Web documents, which are written in RDF."

Unlike vanilla XML, RDF vocabularies can be freely mixed together in data without prior agreement. So you often see ad-hoc combinations of Dublin Core, RSS1, MusicBrainz, RDF-calendar, FOAF, Wordnet, thesaurus, Geo-info etc etc frequently deployed togethe

Products for discovering and storing metadata, natural language processing, & more. Third link's to Geospatial Semantic Web Blog w/update on Metalink's ability to map its descriptions into RDF.

This piece speaks about the different parts of the Semantic Web and how they fit together. For a high-level interview, take a look at Sandro Hawke's The Semantic Web (Put Simply). On the other hand, if you're a Web developer who's interested in building S

The Semantic Web has promised a new era of easier data integration. This article introduces core Semantic Web concepts and standards and explains how to expose an LDAP directory as a service that Semantic Web applications can consume using the open source

Innovation in making data relevant to the one or two words that we type into a search engine is Web 2.0. Adding to the plethora of data is the advent of social networking, Ajax; shared apps across the back end internet cloud, there are already frameworks

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 th

N3 has been well received for its "scribblability", because it is much more compact and readble than XML RDF, and because it forms a good introduction into many key principles of the Semantic Web.

This is an introduction to Semantic Web ideas aimed at someone with experience in programming, perhaps with Web sites and scripting, who wants to understand how RDF is useful in practice. The aim is to give a feel for what the Semantic Web is, and allow o

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.

he Music Ontology Specification provides main concepts and properties fo describing music (i.e. artists, albums and tracks) on the Semantic Web. This document contains a detailed description of the Music Ontology.

Annotea is a W3C Semantic Web Advanced Development project that provides a framework for rich communication about Web pages through shared RDF metadata. An RDF model of bookmark classification permits multiple classification systems to be related to each

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. FOAF documents are, in

In this column, Uche Ogbuji completes his introduction to XML and semantics, setting the stage for the more practical columns that will follow. Thinking XML addresses knowledge management aspects of XML, including metadata, semantics, Resource Description

Repeat after me: "There is no syntax." In order to use and gain advantage from RDF, you do not have to use any particular syntax -- not even the syntax specified in the RDF 1.0 specification. Uche Ogbuji discusses the importance of XML/RDF interchange, of

This guide contains links to many RDF resources including examples, documents, software, tools and projects that use RDF, a standard for describing resources on the web.

Uche Ogbuji moves on to a discussion of a far more sophisticated RDF query language than the primitive API he has discussed thus far. This is the foundation for establishing the middleware for the Issue Tracker article in coming installments. So far, in
