Orion is a C++ implementation of the NGSIv2 REST API binding developed as a part of the FIWARE platform that allows the management of the entire lifecycle of context information including updates, queries, registrations and subscriptions. It is an NGSIv2 server implementation to manage context information and its availability allowing subscription to context information so when some condition occurs notifications are sent. The Industrial Data Space foster secure data exchange among its participants, while at the same time ensuring data sovereignty for the participating data owners. The architecture of the Industrial Data Space does not require central data storage capabilities but follows a decentralized approach, meaning that data physically remain with the respective data owner until they are transmitted to a trusted party. Thus, the Industrial Data Space is not a cloud platform, but an architectural approach to connect various, different platforms.

The Z-Bre4k solution is based on the blackboard architectural model. This model is mainly an artificial intelligence approach, where a common knowledge base, the "blackboard", is iteratively updated by a diverse group of specialist knowledge sources, starting with a problem specification and ending with a solution. Each knowledge source updates the blackboard with a partial solution when its internal constraints match the blackboard state. In this way, the specialists work together to solve the problem. The blackboard model was originally designed as a way to handle complex, ill-defined problems, where the solution is the sum of its parts. The blackboard component acts as a central repository system. The rest of the software applications (components) act independently at the common data structure stored on the blackboard, they respond on changes and create new reactions according to changes. Interaction between components is implemented via the blackboard.

Z-BRE4K ontology supports real-time communication capabilities, by providing an agreement among a shared conceptualization, an explicit formal specification and in-between-relations of objects to support the predictive maintenance domain and data classification. Real-time data is gathered from the shop-floor and sent through the MQTT broker to be consumed by the solution’s prediction software applications in order to predict and provide suggestions. I-Like Machines provide a visualization UI and provide a real-time monitoring of relevant variables and comparison with meaningful thresholds.
Α Web API will return semantic data. The communication interface is through the SPARQL query engine. Z-BRE4K ontology is implemented with the Open Semantic Framework (OSF), an integrated software stack using semantic technologies for knowledge management. Furthermore, JSON formatted data from the shop floor is transferred through a MQTT broker, to be finally stored in I-LiKe machines internal data repository. IDS connectors are used to transform data into the NGSI format, move the data to the ORION context broker to be finally consumed by other applications. Also, the Quality Information Framework (QIF) standard guarantees interoperability since it defines an integrated set of information models that enable the effective exchange of metrology data throughout the entire manufacturing quality measurement process – from product design to inspection planning to execution to analysis and reporting. OpenCPPS (part of AUTOWARE) will provide support for selected mainstream communication protocols and will define the proper interfaces for other communication protocols to be plugged-in.
