Tom Heath and Christian Bizer have been working on a book about Linked Data over the last months. 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 of the book below:
Abstract
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.
