https://w3id.org/standards/isq/ontologies/core/KindOfQuantityQualified Name
isq:KindOfQuantityDefinition
A grouping of quantities that share the same dimension and can therefore be compared, ordered, and added — the most abstract level (L0) of the quantity hierarchy (Dybkaer 2010; Pendrill 2024, Table 1.1).
Scope Note
Only the quantity axis reaches level 0. Examples: space, time, temperature. Kinds are assembled from the ISO/IEC 80000 dataset by shared dimension vector.
