RIF RDF and OWL Compatibility
Abstract Rules interchanged using the Rule Interchange Format RIF may depend on or be used in combination with RDF data and RDF Schema or OWL ontologies. This document, developed by the Rule Interchange Format (RIF) Working Group, specifies the interoperation between RIF and the data and ontology languages RDF, RDF Schema, and OWL.
SPARQL vs. SQL - Intro
This lesson compares the SPARQL and SQL query languages, which are designed to query RDF and relational data, respectively. You may be reading this lesson because you know one and want to learn the other or because you need to make some decisions about which to use for some purpose. First, let's look at their data models; that is, the way we consider their data to be structured. Comparing RDF and SQL data Many people ask what can be done with SPARQL that can't be done with SQL, when in fact they care about what can be done in RDF that can't be done with relational databases. Both of these languages give the user access to create, combine, and consume structured data.

How British do you feel? Visualised
Visualising data online and in a newspaper is like the difference between speaking Spanish and conversing in French; there have the same roots and are ostensibly similar - but in practice are completely different. So it's proven with the results of our online Britishness survey, where we asked readers to rate how they felt about their nationality. The results provide a fascinating insight into how different parts of the UK really feel about the nation as a whole. Online, it works just like a Google map - where you can zoom in and see how people feel in each place, ranked by the maps of each country. It works using the Google Maps API, feeding from a spreadsheet form that readers are essentially filling in.
The Semantic Web: An Introduction

Open Linked Data Discovery, Proof and Trust
I have been giving more and more thought lately about the top two layers of the semantic web "layer cake" – "proof," and above it, "trust." The lower layers receive a lot of attention – RDF (and other data structures), OWL (and ontologies in general), SPARQL, URIs, and so forth – but trust and proof haven't been, I think, explored with the same depth as other aspects of the semantic web. I came to wondering, what if those underlying lower layers came together? What if there was widespread adoption of these technologies, and heaps of well-structured, properly-linked data became available? In this sea of linked data, wouldn't there be some resources that deliberately misrepresented their origin, the data they provided, or both?
Royal Society journal archive made permanently free to access
26 October 2011 Around 60,000 historical scientific papers are accessible via a fully searchable online archive, with papers published more than 70 years ago now becoming freely available. The Royal Society is the world’s oldest scientific publisher, with the first edition of Philosophical Transactions of the Royal Society appearing in 1665. Henry Oldenburg – Secretary of the Royal Society and first Editor of the publication – ensured that it was “licensed by the council of the society, being first reviewed by some of the members of the same”, thus making it the first ever peer-reviewed journal. Philosophical Transactions had to overcome early setbacks including plague, the Great Fire of London and even the imprisonment of Oldenburg, but against the odds the publication survived to the present day. Its foundation would eventually be recognised as one of the most pivotal moments of the scientific revolution.
How Best Buy is Using The Semantic Web
Yesterday we wrote about the increasing usage of Semantic Web technologies by large commercial companies like Facebook, Google and Best Buy. The Semantic Web is a Web of added meaning, which ultimately enables smarter and more personalized web apps to be built. In this post we explore how a leading U.S. retailer, Best Buy, is using a Semantic Web markup language called RDFa to add semantics to its webpages. This is not just an academic exercise for Best Buy. As we will see, semantic technology has already led to increased traffic and better service to its customers. We spoke to Jay Myers, Lead Web Development Engineer at BestBuy.com, to find out how.

Case Study: CRUZAR — An application of semantic matchmaking for eTourism in the city of Zaragoza
Maria Jesús Fernández, City Council of Zaragoza and Antonio Campos, CTIC Foundation, Spain August 2008 General Description The web is a big showcase for cities that want to build their tourism industry. Nowadays, many tourists plan their trips in advance using the information that is available on web pages. Cities compete against each other to offer the most attractive and complete information and services through the tourism section of their web sites.
