• check usage of removed classes: FinalProcess
• check usage of new classes: GeometryChangingProcess, LengthChangingProcess, Thinkness, TransitionPoint, TransitionPointTestingRate, ValueObject (see below)
• check usage of changed IRIs: NodeType class to NodeSeries
• Change object-properties that model a connection between a class instance and a QuantityValue to a ValueObject
• Sort specific material properties (e. g. Conductivity) into material property classes/categories (e. g. ElectricalProperty)
