FYI ---------- Forwarded message ---------- From: Chris Bizer <chris@bizer.de> Date: Thu, Feb 17, 2011 at 4:05 PM Subject: ANN: New book about Linked Data published To: public-lod <public-lod@w3.org>, Semantic Web <semantic-web@w3.org>, semanticweb@yahoogroups.com Hi all, Tom Heath and I have been working on a book about Linked Data over the last months. We are very happy to announce today that the PDF version of the book is available from Morgan & Claypool Publishers. The 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. It discusses patterns for publishing Linked Data, describes deployed Linked Data applications and examines their architecture. The book is published by Morgan & Claypool in the series Synthesis Lectures on the Semantic Web: Theory and Technology edited by James Hendler and Frank van Harmelen. See: http://www.morganclaypool.com/doi/abs/10.2200/S00334ED1V01Y201102WBE001 The PDF version of the book is currently accessible to members of organizations that have licensed the Morgan & Claypool Synthesis Lectures collection. In addition, the PDF version of the book can be purchased for 30 US$ via the Morgan & Claypool website. Within the next two weeks, the print version of the book will be available at Amazon. A bit later, the print version will be available via other channels and can also be ordered directly from Morgan & Claypool. On March 1st, 2011, we will publish a free HTML version of the book at http://linkeddatabook.com/ We are currently still busy with producing the HTML version, so please excuse the delay. Please find the abstract and table of contents of the book below: Abstract of the Book The World Wide Web has enabled the creation of a global information space comprising linked documents. As the Web becomes ever more enmeshed with our daily lives, there is a growing desire for direct access to raw data not currently available on the Web or bound up in hypertext documents. Linked Data provides a publishing paradigm in which not only documents, but also data, can be a first class citizen of the Web, thereby enabling the extension of the Web with a global data space based on open standards - the Web of Data. In this Synthesis lecture we provide readers with a detailed technical introduction to Linked Data. We begin by outlining the basic principles of Linked Data, including coverage of relevant aspects of Web architecture. The remainder of the text is based around two main themes - the publication and consumption of Linked Data. Drawing on a practical Linked Data scenario, we provide guidance and best practices on: architectural approaches to publishing Linked Data; choosing URIs and vocabularies to identify and describe resources; deciding what data to return in a description of a resource on the Web; methods and frameworks for automated linking of data sets; and testing and debugging approaches for Linked Data deployments. We give an overview of existing Linked Data applications and then examine the architectures that are used to consume Linked Data from the Web, alongside existing tools and frameworks that enable these. Readers can expect to gain a rich technical understanding of Linked Data fundamentals, as the basis for application development, research or further study. Table of Contents 1.

Summarizing the state of the art in Linked Data was a job that needed doing -- we are glad they asked us. It has been a long process, throughout which Mike Morgan of Morgan & Claypool has shown the patience of a saint, for which we are extremely grateful. Richard Cyganiak wrote a significant portion of the 2007 tutorial How to Publish Linked Data on the Web, which inspired a number of sections of this book -- thank you Richard. Mike Bergman, Dan Brickley, Fabio Ciravegna, Ian Dickinson, John Goodwin, Harry Halpin, Frank van Harmelen, Olaf Hartig, Andreas Harth, Michael Hausenblas, Jim Hendler, Bernadette Hyland, Toby Inkster, Anja Jentzsch, Libby Miller, Yves Raimond, Matthew Rowe, Daniel Schwabe, Denny Vrandecic, and David Wood reviewed drafts of the book and provided valuable feedback when we needed fresh pairs of eyes -- they deserve our gratitude. We also thank the European Commission for supporting the creation of this book by funding the LATC -- LOD Around The Clock project (Ref. No. 256975). Lastly, we would like to thank the developers of LaTeX and Subversion, without which this exercise in remote, collaborative authoring would not have been possible.
