These more specialized services must be specific to each
      application since the answers may be application dependent, but
      the basic name to address translation is application independent.

APPENDIX D

   Further Discussion of Interoperability and Protocol Translations

   The translation of protocols from one system to another is often
   quite difficult.  Following are some questions that stem from
   considering the translations of addresses between mail systems:

      What is the impact of different addressing environments (i.e.,
      environments of different address formats)?

      It is noted that the boundary of naming environment may or may not
      coincide with the boundary of different mail systems. Should the
      conversion of naming be independent of the application system?

      The boundary between different addressing environments may or may
      not coincide with that of different naming environments or
      application systems.  Some generic approach appears to be
      necessary.

      If the conversion of naming is to be independent of the
      application system, some form of interaction appears necessary
      between the interface module of naming conversion with some
      application level functions, such as the parsing and modification
      of message text.

      To accommodate encryption, conversion may not be desirable at all.
      What then can be an alternative to conversion?

GLOSSARY

   address

      An address is a numerical identifier for the topological location
      of the named entity.

   name

      A name is an alphanumeric identifier associated with the named
      entity.  For unique identification, a name needs to be unique in
      the context in which the name is used.  A name can be mapped to an
      address.

   complete (fully qualified) name

      A complete name is a concatenation of simple names representing
      the hierarchical relation of the named with respect to the naming
      universe, that is it is the concatenation of the simple names of
      the domain structure tree nodes starting with its own name and
      ending with the top level node name.  It is a unique name in the
      naming universe.

   partially qualified name
