Industrie 4.0 service architecture Semantic interoperability in Industrie 4.0 service systems

A key-enabler for the self-organization of production systems proclaimed by the Industrie 4.0 is a standardized core service system. This requires a certain degree of interoperability between participants of the service system that allows to perform Plug and Produce on top of it. The main expectations regarding such as service system are therefore to allow for easy discovery as well as machine readable semantics of data. The service architecture serves as basis for implementing the Administration Shell as well as Industrie 4.0 compliant communication. The underlying service architecture needs to describe the static base structure of data (the Industrie 4.0 Information Meta-Model), the interactive access interfaces for browsing and modifying data (the Industrie 4.0 Information Services) as well as addressing services within their service system. Based on this architecture high-level services for organizing the actual production and handling of products (the Industrie 4.0 Application Services), as well as the self-organization of resources and assets in the automation system (the Industrie 4.0 Platform Services) can be created in a technology-independent and interoperable way.
