Towards declarative programming and querying in a distributed Cyber-Physical System: The i-VISION case

Cyber-Physical Systems that interconnect components of different vendors and knowledge domains bring together a multitude of data schemas and interaction paradigms. In the i-VISION project, we integrate Virtual Reality technologies with Human Factors analysis methods using Semantic Technologies to allow for improved aircraft cockpit design. In this paper, we present the case of the i-VISION project, specifically the software the project develops, describe its architecture and show how we allow for integrated querying by connecting a flight simulator, a Virtual Reality engine, and a Human Factors analysis tool. We use a gateway between the simulator part of the system, which follows the publish/subscribe paradigm, and the Human Factors analysis part, which follows the REST architectural style. We model the data using Semantic Web languages, make the data available using web protocols, and integrate and query the data using a rule engine for Linked Data.
