Information technology — Open Distributed Processing — Type Repository Function

The concept of “type” is fundamental to ODP systems; the interaction model of ODP-RM involves strongly-typed

interactions.

This Recommendation | International Standard:

? defines a framework for describing types of interest in ODP systems by determining what entities need to

be typed and what needs to be said about the identified types. The primary focus of this work is the

computational interface type system;

? identifies and characterizes type languages sufficient to describe the types identified above in an

informative annex;

? provides enterprise, information, and computational specifications of a generic type repository function

within the type description framework which can be specialized to select a specific type system or type

notation. The type repository function provides:

? storage and retrieval of type descriptions;

? management of type descriptions;

? management of the relationship between types including matching of types;

? naming of types (in a manner consistent with ODP Naming Framework);

? interworking and federation of different type repositories.

This Recommendation | International Standard provides a standard method of accessing type descriptions used within

open distributed processing systems, where the type descriptions can be in various concrete syntaxes and type languages

used in these open distributed processing systems. This Recommendation | International Standard also facilitates the

dynamic matching of types for interactions, binding and trading purposes.
