2.2.5.2 Packaging layer

The OSI packaging layer specifies how components that use the OSI data layer, for example, sensor models, are packaged for exchange.

This specifies model types and their mandatory and optional OSI inputs, OSI outputs, and parameter interfaces. A model type may be, for example, a sensor model or a traffic participant model. The packaging layer also specifies component technology standards. This makes it possible to encapsulate model types in easily exchangeable component packages that can be used across platforms and implementations.

Multiple packaging layer implementations are possible within the OSI framework. The shared data layer ensures easy bridging between the different implementations. The currently defined central packaging layer is the OSI Sensor Model Packaging (OSMP) specification. It is based on FMI 2.0 cite:[fmi2.0] and uses certain additional conventions to allow packaging of OSI using models as FMUs.
