From Mary Sue to Magnificent Bastards: TV Tropes and Spontaneous Linked Data – Kurt Cagle

“Bella was such a Mary Sue!” my teenager said in disgust after she got home from seeing the movie Twilight.
“Mary Sue?”
“Yeah, you know, she was like this little too perfect girl. Talk about epic fail!” she replied heading upstairs. “I promised my cosplay group I’d IM them when I got back and talk more about it.”


Semantic Web modeling languages like OWL offer a standard way to define domain concepts and their relationships. This alone, however, can’t fully address the need for describing executable behavior. Using the domain models for data validation, transformation and other application specific reasoning typically requires expressivity of rule languages. In this webinar we show how to use SPARQL to define efficient business rules and constraint checks that will work with any RDF database.

TopQuadrant Hosts Part Two of Webinar Series on building Dynamic Business Applications using SPARQL and SPIN

TopQuadrant will host the second of a three-part Webinar series on building Dynamic Business Applications with SPARQL and other Semantic Web technologies on Wednesday, April 1 at 2pm ET. The session will spotlight SPIN, a light-weight extension of SPARQL. SPIN allows developers to build Semantic Web models that use SPARQL to define efficient business rules and constraint checks for data validation that will work with any RDF database.

Dating Tips for the Semantic Web

I was a bit … weird … as a teenager. As part of an Air Force family we moved frequently, and like most teenagers trying to distinguish themselves from their peers, I tried to use my strengths – an active intellect and an ease at working with abstractions – as a way of establishing myself in the new schools I constantly found myself in. I was the “smart kid”, the one who took to carrying around large books with titles such as “Principia Mathematica” by Bertrand Russell and Whitehead Alfred North in order to impress people with my intelligence (okay, so perhaps my social intelligence was not quite as well developed at that stage).

High Semantics in a Down Economy – Jeff Pollock

It’s tough times out there for little companies swimming in big markets, and unlike some pundits, I don’t pretend that the Semantic Web has already “made it” as a quantifiable software market. In the Semantic Web for Dummies book, I’ve tried to offer a lot of practical advice about which uses of the Semantic Web are making people’s lives easier today.

Pointer Methods in RDF: First Draft

The Evaluation and Repair Tools Working Group at the W3C published the Pointer Methods in RDF as a First Public Working Draft. This document provides a framework for representing pointers to identify locations in content or portions of content, RDF.

David Wood – O’Reilly Media Joins the Semantic Web

O’Reilly Media (, the current name for the geek publishing giant founded by Tim O’Reilly, has finally joined the Semantic Web.  O’Reilly’s coining of the term “Web 2.0″ and early misunderstandings of the Semantic Web stack lead some to think that he didn’t see much value in machine readable information.  That seems to have changed, at least in within <a href=”“>O’Reilly Labs</a>.
