The resulting global geometry is locally defined by the links structure. An important feature of the actual Web is that links are somehow completely independent of content of objects. The links are not typed. We'll return to this important point further on. Let's focus first on two structural aspects of that links geometry.
Global geometry is defined locally.
To create or to delete a link has generally only local incidence given the general redundancy of links. But it may sometimes change drastically the wide-scale geometry by reconnecting or disconnecting huge parts of the Web. This lack of global visibility seems to be structural and irreversible. One may even ask if such a representation is necessary or even useful. A representation is a tool, not a purpose in itself, except for map collectors.
