Linked Data (Paperback)

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.

萬維網使得連結文件組成的全球資訊空間成為可能。隨著網絡越來越深入我們的日常生活，人們對於無法在網絡上或者在超文本文件中獲取的原始數據的需求也越來越大。連結數據提供了一種出版範式，其中不僅文件，還有數據可以成為網絡的一等公民，從而基於開放標準擴展了全球數據空間 - 數據網絡。在這本綜合講義中，我們為讀者提供了對連結數據的詳細技術介紹。我們首先概述了連結數據的基本原則，包括相關的網絡架構方面。接下來的內容圍繞著兩個主題展開 - 連結數據的發布和使用。通過實際的連結數據場景，我們提供了有關以下方面的指導和最佳實踐：發布連結數據的架構方法；選擇用於識別和描述資源的統一資源標識符（URIs）和詞彙；在網絡上描述資源時返回哪些數據；自動連結數據集的方法和框架；以及連結數據部署的測試和調試方法。我們概述了現有的連結數據應用，然後檢視了用於從網絡中消費連結數據的架構，以及現有的工具和框架。讀者可以期望在應用開發、研究或進一步學習的基礎上獲得對連結數據基礎知識的豐富技術理解。目錄：圖表清單 / 引言 / 連結數據原則 / 數據網絡 / 連結數據設計考慮 / 發布連結數據的方法 / 使用連結數據 / 總結和展望
