Collaboration Oriented Architectures (COA) describes information architectures that comply with the COA framework, which in turn is described in the associated COA Framework paper1. COA-compliant information architectures enable enterprises that use them to operate in a secure and reliable manner in an environment of increasing information threat, and where it is the growing norm to interact without boundaries, irrespective of the location of the data or the number of collaborating parties.  This paper explains the COA concept and sets out the essential requirements that are needed in a COA-compliant information architecture. The COA Framework paper presents an architectural view of the principal components in a COA-compliant architecture. Supporting papers then describe these components as required.   While many organizations are trying to respond to the de-perimeterization issue, they often lack a framework and set of guiding principles to organize and implement specific solutions.  This paper and its associated COA Framework paper, together with the Jericho Forum “design principles” (commandments2) aims to fill this gap.  This paper focuses on the need to have business processes that operate across and between multiple organizations, probably (but not necessarily) using the Internet as the common transport mechanism.  In this environment, users and end-systems must securely interact with, or use services from, disparate systems that are outside any single locus of control or security domain. Implementing a COA entails adoption of the Jericho Forum Commandments (JFC) (specifically Jericho Forum design principles #4 to #83) covering the areas of operating in a hostile environment, trust, and authentication.
