 OSI Sensor Model Packaging specifies ways in which models (like e.g. environmental effect models, sensor models and logical models) using the [Open Simulation Interface (OSI)][] are to be packaged for their use in simulation environments using FMI 2.0.
 The specification can be found in the [doc/specification.rst](doc/specification.rst) document in this repository.
