Giant Global Graph. Well, it has been a long time since my last post here.

So many topics, so little time. Some talks, a couple of Design Issues articles, but no blog posts. To dissipate the worry of expectation of quality, I resolve to lower the bar. More about what I had for breakfast. Linked Data: Evolving the Web into a Global Data Space. This book gives an overview of the principles of Linked Data as well as the Web of Data that has emerged through the application of these principles.

Linked Data: Evolving the Web into a Global Data Space

The book discusses patterns for publishing Linked Data, describes deployed Linked Data applications and examines their architecture. The World Wide Web has enabled the creation of a global information space comprising linked documents. Semweb4j. You know Java, and now You want to use semantic technologies or build semantic web applications?

RDF - Semantic Web Standards. Overview RDF is a standard model for data interchange on the Web.

RDF - Semantic Web Standards

RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Virtuoso. Jena Semantic Web Framework. Sesame. DBpedia. DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web.

DBpedia

DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data. We hope that this work will make it easier for the huge amount of information in Wikipedia to be used in some new interesting ways. How to publish Linked Data on the Web. This document provides a tutorial on how to publish Linked Data on the Web.

How to publish Linked Data on the Web

After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web. This tutorial has been superseeded by the book Linked Data: Evolving the Web into a Global Data Space written by Tom Heath and Christian Bizer. This tutorial was published in 2007 and is still online for historical reasons. The Linked Data book was published in 2011 and provides a more detailed and up-to-date introduction into Linked Data. The goal of Linked Data is to enable people to share structured data on the Web as easily as they can share documents today.
