More general references on Architecture and Open Systems are available in Peter Henderson's Open Systems bibliography

There are a huge number of documents on MOSA available on the web. The US DoD, in particular (for whom MOSA means Modular Open Systems Approach, not Architecture) have published guidelines, standards and advice through their OSJTF programme over the last ten years. A selection of these Defence related papers is listed below.

The following references are listed with the most recent first.

2004 Open Systems Policies and enforcement challenges Col. Kenneth Flowers and Cyrus Azani From the preamble: The guidance contained in this paper will assist government Acquisition Program Managers, their staff, and contractors to become more familiar with the DoD Modular Open Systems Approach (MOSA) concept and policies, and better understand the steps needed to more effectively comply with the MOSA policy requirements contained in the DoDD 5000.1 and other DoD directives.

2001 The Test and Evaluation Challenges of Following an Open System Strategy - Cyrus H. Azani Senior Systems Engineer Information Technology and Systems Group TRW Corporation From the abstract: This paper elaborates on distinctions between closed and open systems and will discuss strategies for implementing open systems. The paper also reviews and discusses the test and evaluation challenges associated with open systems and proposes a number of critical developmental issues as a checklist to supplement the information gathered by testers. The paper also emphasizes that the test of openness for the interfaces within a system must only be done when operational and developmental requirements either directly or indirectly require open system implementation and the use of open standards for selected interfaces within a system.
