BS ISO/IEC 9594-1:2017 provides the directory capabilities required by OSI applications, OSI management processes, other OSI
layer entities, and telecommunications services. Among the capabilities which it provides are those of "user-friendly
naming", whereby objects can be referred to by names which are suitable for citing by human users (though not all objects
need have user-friendly names); and "name-to-address mapping" which allows the binding between objects and their
locations to be dynamic. The latter capability allows OSI networks, for example, to be "self-configuring" in the sense that
addition, removal and the changes of object location do not affect OSI network operation.
The Directory is not intended to be a general-purpose database system, although it may be built on such systems. It is
assumed, for instance, that, as is typical with communications directories, there is a considerably higher frequency of
"queries" than of updates. The rate of updates is expected to be governed by the dynamics of people and organizations,
rather than, for example, the dynamics of networks. There is also no need for instantaneous global commitment of updates;
transient conditions, where both old and new versions of the same information are available, are quite acceptable.
It is a characteristic of the Directory that, except as a consequence of differing access rights or un-propagated updates,
the results of directory queries will not be dependent on the identity or location of the inquirer. This characteristic renders
the Directory unsuitable for some telecommunications applications, for example some types of routing. For cases where
the results are dependent on the identity of the inquirer, access to directory information and updates of the Directory may
be denied.
