• IDL: Interface Definition Language
– IDL is the means by which a particular object implementation tells its
potential clients what operations are available and how they should be
invoked.
• Language mapping: recipe how to generate stubs&skeletons from
IDL
– Clients see objects and ORB interfaces through the perspective of a
language mapping, bringing the object right up to the programmer’s
level.
• Interface Repository: where all interfaces are stored network-wide
– provides information on interfaces at run-time
• DII: Dynamic Invocation Interface
– construct a remote method call at run-time without the use of stubs
