+    fmu_path:
+      format: uri
+      description: |
+        Specifies the URI to a FMU model
+
+    fmu_unpack_path:
+      format: uri
+      description: |
+        Specifies the URI to a directory which has the unpacked files of the FMU model (mainly the shared library and the modelDescription.xml for the model)
+
+    fmuWritefirst:
+      type: boolean
+      description: |
+        Specifies whether the model has to be writtem with input values before running. `true` denotes that the model should use the input values. `false` would make the model use default values instead.
+
+    startTime:
+      type: number
+      description: |
+        Specifies the start time for the simulation. Value has to be at least one `stepSize` lesser than `stopTime`.
+
+    stopTime:
+      type: number
+      description: |
+        Specifies the stop time for the simulation. The number of steps is calculated then by the difference between `startTime` and `stopTime` divided by the `stepSize`.
+
+    stepSize:
+      type: number
+      description: |
+        Specifies the stepSize for the simulation. Special care has to be taken to ensure that the value is equal to the value mantioned in modelDescription.xml.
