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
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
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.
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
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. RDF is an application of the Extensible Markup Language XML.
xmlns.com is an internet domain created for the purposes of simple Web namespace management. The rationale for registering xmlns.com was to secure a short, memorable domain suitable for naming concepts for use in RDF and XML vocabularies.
FOAFCorp: Corporate Friends of Friends What is this? RDF is a great data format for describing interconnected entities. With FOAF, we have a simple fun vocabulary for describing social networks, people, organisations etc. The FOAFCorp experiment extends
This column, the third in a series, shows how to add semantic knowledge to an RDF application by incorporating WordNet synonym sets. With the added knowledge of the WordNet lexical database, you can search a set of RDF data for related concepts, not just
The basis of RDF's strength as a knowledge-management tool is that it allows you to organize, interrelate, classify, and annotate this knowledge, thereby increasing the aggregate value of the stored data. RDF has a reputation for complexity that is belied
