QuantityKind

VEC-Root The diagram above defines the class VecContent which is intended to be regarded as the top-level root element for VEC documents. It is the declared entry point to the information that a VEC file contains.

Multidimensional Values The MultiDimensionalValue concept is used to describe properties that are represented by multiple values across different dimensions — for example, a characteristic curve. The dimensions, e.g., tripping time and current for a fuse characteristic, of a MultiDimensionalValue are defined by referencing the corresponding QuantityKinds in which the dimensions are expressed.

A QuantityKind is any observable property that can be measured and quantified numerically. Familiar examples include physical properties such as length, mass, time, force, energy, power, electric charge, etc. A quantity (not represented as class in the VEC) would always be associated with the context of measurement (i.
