Unambiguity

This is the requirement that a name should refer to one object and one object alone. This is a prerequisite of resolvability, but there are many systems which require unambigity and uniqueness without resolvabiolity. These systemns need to be able to that comparison of object names is equivalent to comparing the dcouments.

This allows large distributed systems to keep track of changes and replicated documents without moving the documents around.

Hardly any existing schemes allow ambiguous names, although someof course (such as filenames) aur unambiguous oinly within a local scope such as a file system.

By contrast, the property of uniqueness is much rarer.
