From the reviews: "The book focuses on technologies and methodologies that can provide better utilization of metadata within spatial data infrastructures. ... The concepts exposed, in addition to the examples and a thorough corpus of additional bibliographic references, will bring readers to a better understanding of the design and management of future geospatial data infrastructures. This is an excellent book, which I recommend reading." (Alessandro Berni, ACM Computing Reviews, Vol. 49 (5), 2008)
