This book provides a conceptual and technical introduction to the field of Linked Data. It is intended for anyone who cares about data – using it, managing it, sharing it, interacting with it – and is passionate about the Web. We think this will include data geeks , managers and owners of data sets, system implementors and Web developers. We hope that students and teachers of information management and computer science will find the book a suitable reference point for courses that explore topics in Web development and data management. Established practitioners of Linked Data will find in this book a distillation of much of their knowledge and experience, and a reference work that can bring this to all those who follow in their footsteps.
