This SAE Aerospace Standard (AS) establishes a Generic Open Architecture (GOA) Framework for application independent hardware/software systems. This document defines the interface classes for the GOA Framework. Supplemental documents define the guidelines for applying the GOA Framework to specific applications. Purpose: The purpose of this document is to provide a framework to identify interface classes for applying open systems interface standards to the design of a specific hardware/software system. This framework is used to define an abstract architecture based on a generic set of interface points. The generic set of system interface points facilitate identification of critical interfaces. It is intended that the GOA Framework be specialized for varying domains. A domain specific implementation of the GOA Framework will increase the chance that components/capabilities produced independently will ??plug and play?? and evolve affordably within the domain. The GOA Framework provides a basis for commonality for both vendors and users of components/ capabilities. Application of the GOA Framework will impose constraints on individual domains and implementations. This will increase the likelihood that independently produced products will interoperate. Application of the GOA Framework together with the appropriate open system interface standards is expected to provide the following benefits to future programs: a. Provide the basis for establishing a set of specifications@ standards and procedures that will become common to all elements of a major system. b. Ensure that future systems can be upgraded and maintained with minimal redesign impact to the existing system by establishing the interfaces required to enable modular replacement of hardware and software. c. Promote availability of multiple sources of needed software and hardware@ especially commercial off-the-shelf components. d. Provide a pool of hardware and software modules for multiple program commonality and re-use. e. Insure access to the architecture and its design documentation for any vendor or agency desiring to propose new uses and applications@ and to facilitate competition to contain cost growth. Application Guidance: This document is intended to be used by both system designers and system implementors in the development of open systems architectures. Domain specific guidelines should be developed to provide clarification for application of the GOA Framework. Document Structure: This document is structured as follows: a. Section 1 defines the scope and purpose of this document. b. Section 2 lists documents referenced within this document@ and definitions and terminology used in this document. c. Section 3 presents GOA Framework requirements. d. Section 4 provides applicable notes to the GOA Framework standard.
