CAPE-OPEN

Common interfaces
Questions related to horizontal interface specification documents for handling concepts that may be required by any business interface. This collection of interfaces support basic functions and are always independent of business interfaces.

Business interfaces
Gathers questions related to vertical interface specification documents. These interfaces are domain-specific interfaces for CAPE applications. They define CAPE-OPEN components involved in a CAPE-OPEN process simulation application. Business interfaces can be roughly grouped in four categories: numerics, unit operations, thermodynamic and physical properties and others.
