The view of a universal space of information as the (infinite) generalization of a library is an extremely useful one. It includes almost all facets the authors would like to incorporate when abstracting and modeling such an artifact. There is one crucial slant, though: the library is composed of books, let them say in Web terms, of documents. Documents (books) are artifacts produced by humans to be consumed by humans. If one replaces data in the place of books, the authors essentially have an abstract model of the "Web of Data". But this is not a minor change, bringing with it complex challenges.
