Kolonnval

Kolonnval is a term encountered in some Swedish-language contexts that generally refers to the act of selecting one or more columns from a data table or dataset, or, in a broader sense, making decisions about which columns to include in a design or display. The word combines kolonn (column) and val (choice or selection). It is not a standardized term in English-language literature and may appear primarily in niche or informal discussions.

In data science and information technology contexts, kolonnval describes columnar projection: choosing a subset of columns for analysis, processing, or storage. This is equivalent to the projection operation in relational algebra or to column subsetting in data-frame libraries. Practically, kolonnval appears when analysts decide to retain only certain features, such as selecting the columns for name and date of birth before further transformation.

In architecture or design discussions, kolonnval can, in informal usage, refer to decisions about which columns in a colonnade to emphasize, space, or visually balance. However, this usage is not common or standardized and is not widely recognized as a formal term in architectural practice.

Limitations and caveats: because kolonnval is not widely standardized, its meaning is highly context-dependent and may lead to ambiguity. In formal writing, it is advisable to use more specific terminology such as column selection, projection, or colonnade planning, depending on the domain.
