This new edition of REEEP’s highly successful manual Linked Open Data: The Essentials offers a solid introduction to Linked Open Data (LOD) principles, with new case studies and updated information on how to make the most of the possibilities LOD has to offer. The manual is particularly targeted at knowledge brokers working in the climte change sector, with most of the examples and case studies focused on this area, but the general principles are broadly applicable to other disciplines and sectors.
