Ominaisuustasoisia

Ominaisuustasoisia is a Finnish adjectival form derived from the compound noun "ominaisuustasoinen", literally meaning "of attribute level" or "feature-level". It combines "ominaisuus" (attribute, feature) and "tasoinen" (levelled, of a certain level), with "tasoisia" representing a plural inflection used in partitive or plural contexts. The word is typically used to describe things that pertain to, operate at, or are measured at the level of individual attributes or features.

In practice, ominaisuustasoisia appears in technical, academic and bureaucratic Finnish where distinctions between levels of analysis are important. Examples include software requirements (feature-level changes), data modeling (attribute-level metadata), quality assessment (attribute-level indicators) and ontology work. As an adjective it qualifies nouns to indicate that the focus or unit of concern is the attribute rather than an aggregate or system level.

The term illustrates a productive element of Finnish word formation, where nouns are combined with "-tasoinen" to express hierarchical or comparative levels. While primarily used in Finnish-language discourse, its conceptual equivalents in English include "attribute-level" or "feature-level". Usage is generally specialized and context-dependent; outside technical registers speakers may prefer simpler expressions to convey the same idea.
