all of its users to work in a common and unified approach – leading towards high levels of interoperability.

A. Overview of Arrowhead Framework The Arrowhead Framework includes principles on how to

design SOA-based systems, guidelines for its documentation and a software framework capable of supporting its implementations.

The design guidelines provide generic “black box” design patterns on how to implement application systems to be Arrowhead Framework compliant. Furthermore, these guidelines allow making legacy systems Arrowhead Framework compliant.

The documentation guidelines include templates for service, system and, system-of-systems descriptions (to be detailed in the following sections of this paper). Due to its complexity there is also a “Cookbook” for hands-on instructions on how to use the framework.

The software framework (Fig. 2) includes a set of Core Services which are capable of supporting the interaction between Application Services. The Core Services handle the support functionality within the Arrowhead Framework to enable Application Services to exchange information. Examples are services for Discovery, Authorization, Orchestration, and System Status. An Application Service handles the data exchange between specialized devices (those that the system is special at). Examples are services for sensor reading, billing, energy consumption, weather forecasts, etc.

The Core Services (Fig. 2) are further divided into three different groups: i) Information Infrastructure (II); ii) Systems Management (SM); and, iii) Information Assurance (IA).

The II services are the set of core services and systems in charge of providing information about the services and how to connect to them. This includes services like Service Discovery, Application Installation and Setup, Service Metadata, etc. The SM services are the set of core services and systems providing support for late binding and solving system-of-systems composition. The SM provides logging, monitoring and status functionality. It also addresses orchestration, software distribution, Quality of Service (QoS), configuration and policy. Finally, such a software framework can only operate if the system is able provide adequate security and safety levels. Those functions are assured by the IA services, supporting secure information exchange. Example services include those for authorization, authentication, certificate distribution, security logging and service intrusion.

The software framework also addresses the design and prototype implementations of gateways/mediators for making legacy systems Arrowhead compliant.

Finally, the Arrowhead Framework provides a set of rules and principles to: i) address technical property requirements; ii) Arrowhead conformity requirements and, iii) a set of tool(s) for conformity test and verification.

B. The Arrowhead Framework documentation approach The Arrowhead Framework states a common approach of

how to document SOA-based systems. The documents structure is built on three levels, namely: System-of-Systems, System and Service level. These are depicted in Fig. 3, showing the links between documents, as well.

Fig. 3. The Arrowhead Framework documentation relationships

The approach is to apply the terms “black box” and “white box” only to the System level since it is well known what it means. However, these concepts are not used at the Service level, where such division is rather meant to be about technology independence/dependence.

At the System-of-Systems (SoS) level, a concrete “System-of-Systems type” is defined in the System-of-Systems Description (SoSD) document. Thus, the particular “system type” needed to fulfill our SoS goals can be implemented. The correct way of working is assured thanks to the “black box” representation of all Systems in the System Description (SysD). Therefore, each “system type” can talk to each other or identify the gateways/mediators’ needs.

In the System-of-Systems Design Description (SoSDD) a SoSD instance can be created. All the participating “white box” Systems (SysDD) must be enumerated and the entire setup must be explained, including infrastructure description (network configuration, VPNs, etc.), domain structure, startup behavior etc. This is a deployment description and it describes the SOA installations.
