In this upcoming world of the Internet of Things, global interconnectedness and interoperability is promised between any device at any time - all orchestrated run-time in a distributed manner. However, this grand challenge assumes new fundamentals and approaches that are far from existing let alone being proven. Creating functioning networks of smart things even in smaller scale, or for 50 billion devices [1], is still a very active research area.

Nevertheless, industrial applications are also pitching in, flexibility, interoperability and integrability of legacy and new devices is of their high interests. Creating industrial (e.g. manufacturing) processes by utilizing modern concepts and technologies while retaining e.g. QoS, safety or security is also not a minor task.

The Arrowhead Project is the vision of a consortium with the backing of the European Union [2]. It aims nothing less than to create a full-scoped framework enabling collaborative automation by networked embedded devices. It targets use cases from five business domains: production (process and manufacturing), smart buildings and infrastructures, electro mobility, energy production and virtual markets of energy.

The Arrowhead Technological Framework is aimed at providing fundamentals, concepts, guidelines and reference architecture implementations to achieve its goal. This service-oriented architecture builds upon cyber-physical systems, integrating and governing them in closed operational environments while traditional industrial technologies and restrictions are still applied.

This work discusses the various core systems and services of the framework that are providing a vast scope of funtionality for such, primarily closed industrial systems [2,3]. During operations, a certain degree of centralized governance is realized, taking into account the various levels of automony and capabilities of the involved cyber-physical systems.

To successfully handle the expectations set for this central governance framework, certain fundamentals, processes, core systems and services had to be refined or newly established . These are naturally part of this work: from the overall analysis of the given problem space within the Industrial Internet of Things worlds, through the details of the implementation up to the verification of the framework in various European pilot projects.
