Tom Heath and Christian Bizer (2011) Linked Data: Evolving the Web into a Global Data Space (HTML edition). Synthesis Lectures on the Semantic Web: Theory and Technology, 1:1, 1-136. Morgan & Claypool:
"The World Wide Web has enabled the creation of a global information space comprising linked 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.""Just as hyperlinks in the classic Web connect documents into a single global information space, Linked Data enables links to be set between items in different data sources and therefore connect these sources into a single global data space."
