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
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
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
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
This Thinking XML column shows how to combine metadata collected from multiple XML source documents into a single Resource Description Framework (RDF) model for effective querying. In this follow-up to his previous installment that introduced how to use X
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
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
FOAF facilitates the creation of the Semantic Web equivalent of the archetypal personal homepage: My name is Leigh, this is a picture of me, I'm interested in XML, and here are some links to my friends. And just like the HTML version, FOAF documents can b
Edd Dumbill explores an XML and RDF application known as Friend-of-a-Friend (FOAF). FOAF allows the expression of personal information and relationships, and is a useful building block for creating information systems that support online communities. Code
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.
DBin is general purpose Semantic Web application that enables power users (domain experts) to create "discussion groups" where users annotate any subject of interest (from "beers" as in our example to anything really). At low level, these annotatins are e
Very cool Semantic Web use case Demo via Piggy Bank's sever component called "Semantic Bank". These complimentary projects are part of the MIT SMILE project. As you can see Web 2.0 and the Semantic Web are mutually inclusive paradigms as reemphasized
RDFWeb is intended to be both fun and technically challenging. We hope that at least some of the writing here will be accessible for a general audience, although much of it will be for the rather small community familiar with the subtleties of various Sem
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
