Table of Contents
The value of this variable is a list of the names of all currently
defined OntoLingua implementations. An OntoLingua implementation is a
CLOS object which represents a supported target representation system.
This variable should never be altered by the user. Implementations
are added to this list when back-end translators are loaded. For
example, the LOOM translator will be loaded if LOOM is around when
Ontolingua is loaded. Then the symbol :LOOM will be on the
*ALL-IMPLEMENTATIONS* list.
The current value of *ALL-IMPLEMENTATIONS* is
(:EPIKIT :CLIPS :LOOM :GENERIC-FRAME :KIF)
