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
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
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
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
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.
Semanlink is a personal information management system based on RDF. It lets you add tags, as well as other RDF metadata, to files, bookmarks and short text notes that it allows to write. Providing a simple way to organize the tags in a graph, it allows yo
"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
On the Semantic Web (SemWeb), computers do the browsing (and searching, and querying, and...) for us. The SemWeb enables computers to seek out knowledge distributed throughout the Web, mesh it, and then take action based on it. Take an analogy: the curren
The Semantic Web is a web of data, in some ways like a global database. When looking at a possible formulation of a universal Web of semantic assertions, the principle of minimalist design requires that it be based on a common model of great generality.
Microformats: Recognizing the complexity of RDF and OWL, the goal of microformats is to embed basic semantics (meaningful relationships) right into HTML pages. It is not as expressive right now as RDF and OWL, but it's compact & and uses at-hand XHTML. A
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 article introduces Resource Description Framework (RDF), developed by the W3C for Web-based metadata, using XML as an interchange syntax. RDF's essential aim is to make work easier for autonomous agents, which would refine the Web by improving search
This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description
RDF--the Resource Description Framework--is a universal format for data on the Web. Using a simple relational model, it allows structured and semi-structured data to be mixed, exported and shared accross different applications. RDF data describe all sorts
