===== Discussion =====

Interface Definition Language (IDL), often referred to as OMG IDL in Object Management Group specifications, defines data types and interfaces in a language-neutral form.

In the Financial Systems [[dido:99_annexes:annex-b-terms-and-definitions:a:archetype|Archetype]] document set, IDL belongs to implementation and platform-specific mapping concerns. IDL does not define logical [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Nodes]], logical [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoints]], logical information structures, logical [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Planes]], or logical interaction patterns.

An implementation profile maps selected logical information structures and logical Communication Endpoints to IDL modules, structures, enumerations, constants, annotations, generated language bindings, and generated type-support artifacts when DDS or another IDL-based technology serves as the selected implementation technology.

===== Definition =====

//language-neutral specification language used to define data types and interfaces for implementation mapping and generated language bindings//

===== Source =====

Generalised from Object Management Group Interface Definition Language usage and its application as an implementation mapping concern in [[fxdemo:04-part:start]].

===== Note =====

IDL is not a logical information structure, logical Communication Endpoint, logical Node, Runtime Plane, DDS Topic, DDS Domain, message bus, programming language, deployment environment, governance model, or evidence model.

===== Example =====

Part 4 maps selected FX Demo logical information structures to IDL structures that support generated Python type bindings for a DDS implementation profile.
