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
Taxonomy of Markup · I use a taxonomy of markup which I'm pretty sure was first advanced in the seminal November 1987 CACM article Markup systems and the future of scholarly text processing, by Coombs, Renear, and DeRose, which was the first place I ever
Machines, with their rigid information processing capabilities, need everything spelled out for them. To be able to do something useful with this title and byline, a machine would need to be able to parse it correctly. It would need to know that the numbe
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.
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
This discussion of XML and semantics kicks off a column by Uche Ogbuji on knowledge management aspects of XML, including metadata, semantics, Resource Description Framework (RDF), Topic Maps, and autonomous agents. Approaching the topic from a practical p
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.
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
This document is not intended to teach you RDF via my own words, but rather to hand-hold you through the "good" parts of the same journey I took. If it looks like a big link-list with menial comments from the peanut gallery, then you're not far off the ma
"Many people have told me this week that they think 'Web 2.0' has not been very impressive so far and that they really hope for a next-generation of the Web with some more significant innovation under the hood -- regardless of what it's called. A lot of p
some time now, I’ve wanted to increase my understanding of microformats. If you’re unfamilar with the term or want to understand the basic purpose of this technology better, I suggest reading Phil Windley’s Microformats: Paving the Cowpaths. I read
Web 2.0 is a vision of the web where content and functions can be remixed and reused to create new content or new applications. Web services and the semantic web are two of the key enablers for this vision but there appears to be dual approaches to both
